Introduction
ST SPC58 (Chorus) 4B Line Emulation Adapter primary use case is providing Nexus trace
functionality for the SPC58 4B Line devices in the QFP packages, where Nexus trace port is not
available. It is based on the 176-pin "superset" device with 2MB program and provides the
adaptation to:
· 64-pin
· 100-pin and
· 144-pin Target package.
The Emulation Adapter might differ in some peripherals from the target device;
therefore, the device datasheet should be checked.
Alternative use case is also a Standalone operation. In this case customer can start developing
and testing the application while his target may not be available yet.
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-SPC584B (Microcontroller part)
· Conversion board
· Solder part

Screws
Slot screw
The Slot screw (30mm) is used to fix the Conversion board to the Solder part. The setup
becomes 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
Emulation Adapter setup.

Configuration
J1: Target reset configuration
Jumper J1 connects the reset line between the emulation device and the target. By default J1 is
populated.
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.
If an oscillator in the target is not an option and the target crystal doesn’t oscillate in
conjunction with the emulation adapter, the emulation adapter 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 emulation adapter.
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 Emulation
Adapter since clock lines (XTAL, EXTAL) between the target crystal and the emulation
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.
The crystal packed separately in the antistatic bag comes along the Emulation Adapter. 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 A2 or lower were delivered with a 40 MHz crystal,
while the adapters of revision A3 or higher are delivered with a 20 MHz crystal.
Crystal Q1 is located in the corner of the emulation adapter, next to the 38-pin Mictor connector
P1 and per default not populated.

Capacitors C50 and C51, for which pads are provided on
the emulation adapter PCB, are not populated since the
microcontroller provides already the internal load
capacitors for 20MHz/40MHz crystal oscillator operation.
J4 and J5: GND connecting points
Real target microcontroller in the QFP 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 emulation adapter usage, the solder part (IA100TQ-SOLDER or IA64ATQ-SOLDER)
is soldered instead of the microcontroller. Note that the available solder parts at the
introduction of this emulation adapter, did not provide support for the exposed GND pad. For
this reason, user must ensure replacement GND connection between the emulation adapter and
the target using a dedicated GND wire. Without this connection, the system will not work. Use
provided GND wire which comes along the emulation adapter and plug it to the pin J5 (see
picture above) on the emulation adapter. 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

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 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, except
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:
· CVDD_HV_OSC (pin 4),
· CVDD_HV_ADV (pin 6),
· CVDD_HV_ADR_S (pin 8),
· CVDD_HV_IO_MAIN (pin 10),
· CVDD_HV_FLA (pin 12),
· CVDD_HV_IO_FLEX (pin 14),
· GND (pins 22, 24, 26) signals.
The EA comes delivered together with the IEA-PS emulation adapter power supply, which simply
plugs into the P2 header row, providing the necessary power supply for Emulation 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.

Power supply package
A Power supply package, which is delivered with the Emulation Adapter, is required when:
· The Emulation Adapter is used as a standalone device .
· The target board doesn’t provide an accurate supply voltage.
· The target board doesn’t provide sufficient current for the Emulation Adapter operation.
The Power converter can supply either 3.3 V or 5 V. Array of jumpers J0 – J9 select 3.3 V or 5 V
voltage on the P3 connector, which connects to the Emulation Adapter.

P3 connector and J0-J9 jumper correlation table
For example, when J2 is in the 3V3 position, it supplies 3.3 V to pin 6 of the P3 connector. When
J2 is in 5V position, it supplies 5 V to pin 6 of the P3 connector pin.
Be careful not to supply 5 V to the microcontroller power supply pin which has
declared maximum voltage 3.3 V! Refer to microcontroller documentation for detailed
information.

Power supply
Use enclosed IEA-PS Emulation Adapter Power converter.

Measurement board
With the Measurement board you gain easy access to all MCU pins respectively, because
modern targets do not have accessible all the MCU pins / connected signals to connect with a
measurement equipment (oscilloscope, logic analyzer).
The Measurement board is optional and connects between the Emulation Adapter and the
Conversion Board. It comes together with an applicable Layout board (black panel where all the
CPU signals are nicely marked) that matches your order. The black panel is placed over the
Measurement board.

Solder parts
In case of soldering the Solder part manually, it’s highly recommended prolonging the solder
pad E on the outer side (e.g., for 1.5-2 mm) during the PCB design. Note that without this
modification, it’s very difficult to solder the Solder part manually.
