Introduction
ST SPC58 (Chorus) H Line Emulation Adapter primary use case is providing Nexus trace func-
tionality for the SPC58 H Line devices in the:
·
144-pin
·
176-pin
·
302-pin
where Nexus trace port is not available.
The Emulation Adapter might differ in some peripherals from the target device; there-
fore, the device datasheet should be checked.
Alternative use case is a Standalone operation, where you can start developing and testing the
application while his target may not be available yet.
ST SPC58 H Line Emulation Adapter is based on the "superset" SPC58NH92C5 device in the
BGA386 package on which the Nexus trace port is also exposed and available (P1 connector).
It’s a "superset" device with 10MB program flash and can emulate all ST SPC58 H Line devices
in smaller packages.
Complete Emulation Adapter is split into individual parts which makes it flexible when support
for different target packages is required. A typical setup in conjunction with the target contains:
·
IEA-SPC58NH (Microcontroller part)
·
Conversion board
·
Solder part

BGA Adaptation: The Target can have electronic components placed around the Micro-
controller within the Emulation Adapter (EA) "ground floor", which impede connecting
the EA to the Target. In such cases the distance of the EA from the Target can be op-
tionally increased in steps of 3.25 mm by inserting the optional Extender. Not more
than two Extenders should be used since every connector affects signal integrity.
·
With no Extender the lowest point of the EA is approx. 4.35 mm away from the Tar-
get.
·
With one Extender the lowest point of the EA is approx. 7.6 mm away from the Tar-
get.
·
With two Extenders the lowest point of the EA is approx. 10.85 mm away from the
Target.
Note that by adding the Extender or two, makes the whole setup less robust. Use cau-
tion with Extenders to prevent breaking of the hardware setup or just part of it.
Fixed Adaptation
The adaptation is elivered with a slot screw, which can be used to achieve a more solid and
stable fixing of the Conversion board and the Solder part.

Screws
Slot screw
The Slot screw (30mm) is used to fix the Conversion board to the Solder part. The setup be-
comes mechanically more robust.Screw the Conversion board to the Solder part first, before the
Emulation Adapter is attached on top and watch out not to break out the Solder part, e.g., if you
accidentally hit the Emulation Adapter from the side.
Short Hexagon socket screw
Short Hexagon socket screw, which comes with the Solder part, is not applicable with this Emu-
lation Adapter setup.
Configuration
J1: Target reset configuration
Jumper J1 connects the reset line and the target reset line. By default, J1 is populated.
When having problems establishing the initial debug session with the Emulation Adapter (EA),
try to remove J1 and see if it makes any difference.
J2 and J3: Clock source configuration
Jumpers J2 and J3 select external clock source (XOSC) for the emulation device. Per default,
both jumpers are set to position 1-2, which yields the external clock (XOSC) source being used
from the Target board.
If an oscillator in the Target is not an option and the target crystal doesn’t oscillate in conjunc-
tion with the EA, the EA can also provide the external clock (XOSC) source by setting jumpers J2
and J3 in position 2-3. In this case, a crystal circuit must be built on the EA.
Note that the EA may not operate when crystal circuit is used in the target. Typical
design guideline is that the crystal should be as close as possible to the microcontrol-
ler.
It can happen that the target crystal does not oscillate in conjunction with the EA since
clock lines (XTAL, EXTAL) between the target crystal and the emulation device on the
EA become too long, inevitably too much affecting the impedance of the crystal cir-
cuit. If a “standalone” oscillator is used instead of the crystal circuit, no problems are
expected.
The crystal packed separately in the antistatic bag comes along the Emulation Ad-
apter. It can be used to feed an external clock source (XOSC) to the emulation device
by inserting the crystal into the Q1 socket. If a different clock frequency is required, use
suitable crystal and insert it into the Q1 socket.
The emulation adapters of revision A1 were delivered with a 40 MHz crystal, while the
adapters of revision A2 or higher are delivered with a 20 MHz crystal.
Crystal Q1 is located in the corner of the EA, next to the 38-pin Mictor connector P1 and per de-
fault not populated:
Capacitors C85 and C86, for which pads are provided on
the EA PCB, are not populated since the microcontroller
provides already the internal load capacitors for 40MHz
crystal oscillator operation.
J4 and J5: GND connecting points
Real target microcontroller in the 176-pin package provides an exposed GND pad in the middle
of the microcontroller at the bottom side of the package. This provides GND connection between
the microcontroller and the target.
In case of the EA usage, the solder part is soldered instead of the microcontroller. Note that
available solder parts until the introduction of this EA, haven't provided support for the exposed
GND pad.
Ensure a replacement GND connection between the EA and the target using a dedicated GND
wire. Without this connection, the system will not work. Use provided GND wire which comes
along the EA and plug it to the pin J5 (see picture above) on the EA. Connect the other side to
the ground potential on the target - as close as possible to the microcontroller respectively
solder part being soldered instead of the microcontroller. This connection must be quality and
reliable otherwise debugging and tracing over the Nexus trace port may not work. Alternatively,
GND connection can be also established over the J4 ground bridge.
J6 and J7: RTC Clock source
Jumpers J6 and J7 select the RTC Clock source (32,768 kHz XTAL) for the emulation device. Per
default, both jumpers are set to position 1-2, which yields the clock source being used from the
target.
If an oscillator in the target is not an option and the target crystal doesn’t oscillate in conjunc-
tion with the EA, the EA can also provide the clock source (XTAL) by setting jumpers J6 and J7
in position 2-3. In this case, a crystal circuit must be built on the EA.
Note that the Emulation Adapter may not operate when crystal circuit is used in the
target. Typical design guideline is that the crystal should be as close as possible to the
microcontroller.
It can happen that the target crystal does not oscillate in conjunction with the Emula-
tion Adapter since clock lines (XTAL, EXTAL) between the target crystal and the emula-
tion device on the Emulation Adapter become too long, inevitably too much affecting
the impedance of the crystal circuit. If a “standalone” oscillator is used instead of the
crystal circuit, no problems are expected.

KEY
P2 Signal description
Refer to the microcontroller user’s manual for more details which power supply designation in
the above table belongs to which power supply.
By default, all jumpers are set and connect target power supply coming from the target to the
microcontroller residing on the Emulation Adapter. In principle, pins 1-2, 3-4, 5-6, 7-8, 9-10, 11-12
and 13-14 must be bridged only but for the convenience and ease of use all jumpers are set, ex-
cept for pins 25-26. Pin 26 is the polarizer key preventing incorrect connection of the IEA-PS
power supply, when being connected.
If a different power source is to be used (e.g., in case of a standalone operation), all jumpers
must be removed and power source must be applied to:
·
VDD_HV_OSC (pin 2),
·
VDD_HV_ADR_S (pin 4),
·
VDD_HV_ADV_S (pin 6),
·
VDD_HV_FLA (pin 8),
·
VDD_HV_IO_MAIN (pin 10),
·
VDD_HV_IO_ETH (pin 12),
·
VDD_HV_IO_EMMC (pin 14),
·
GND (pins 22, 24, 26) signals.
The Emulation Adapter comes delivered together with the IEA-PS emulation adapter power sup-
ply, which simply plugs into the P2 header row, providing the necessary power supply for Emula-
tion Adapter standalone operation. Double check that the power supply is configured properly
for this particular Emulation Adapter.

Be aware that debug and trace signals from the Emulation adapter superset device are
not connected to the target board. They are exposed only to the connectors on the
Emulation adapter.
P3 – P6: Emulation device pinout
Connectors P3, P4, P5 and P6 on the top side of the EA expose all emulation device signals to-
ward the Conversion board through which the EA adapts to different pin count packages.
Conversion board configuration
IEA-SPC58NH-BGA302
Conversion board IEA-SPC58NH-BGA302 consist of 39 DIP switches, which define which altern-
ate port is connected to a specific CPU pin.
With the original microcontroller in the BGA302 package, this is configured through the applica-
tion software. However, when using the Emulation Adapter based on the BGA386 "superset"
device, this configuration has to be performed manually through jumpers DIP1-DIP39 since for
some reason each of the alternate ports is routed to an individual physical pin on the BGA386
device without the possibility for controlling routing by means of application software.
For example, with the original microcontroller in the BGA302 package, the application software
can route either port PQ[15] or port PA[0] to pin A17. However, with the “superset” microcontrol-
ler in the BGA386 package, port PQ[15] is fixed connected to pin L22 and port PA[0] to pin B18.
Hence with the Emulation Adapter you can define with the jumper DIP1 whether port PQ[15] or
port PA[0] is routed to target pin A17 on the 302-pin conversion board.
Set all the DIPs accordingly to exactly match with your application software configura-
tion. Any mismatch in configuration will yield application not operating properly!
DIPs are by default in position 1-2 (enabled).

IEA-SPC58NH-TQ176
Conversion board IEA-SPC58NH-TQ176 consist of 36 jumpers which define which alternate port
is connected to a specific CPU pin.
With the original microcontroller in the QFP176 package this is configured through the applica-
tion software. However when using the Emulation Adapter based on the BGA386 "superset"
device, this configuration has to be performed manually through jumpers J1-J36 since for some
reason each of the alternate ports is routed to an individual physical pin on the BGA386 device
without the possibility for controlling routing by means of application software.
For example, with the original microcontroller in the QFP176 package, the application software
can route either port PQ[15] or port PA[0] to pin 137. However, with the “superset” microcontrol-
ler in the BGA386 package, port PQ[15] is fixed connected to pin L22 and port PA[0] to pin B18.
Hence with the Emulation Adapter you can define with the jumper J1 whether port PQ[15] or
port PA[0] is routed to target pin 137 on the 176-pin conversion board.
Set all the jumpers accordingly to exactly match with your application software configura-
tion. Any mismatch in configuration will yield application not operating properly!
Jumpers are by default set to position 1-2.
