ETAS Hardware Description
4 Hardware Description
In this chapter, the function blocks and the interfaces of the ETK-T2.2G are
explained in detail.
4.1 ETK-T2.2G Versions
The ETK-T2.2G can only be ordered in current variant "G". It is prepared for
different functional and mechanical versions, which can be released as new
products (name and order no.) on request.
The PCB is prepared for following improvements
• The LFBGA292 adapter could be replaced by an LFBGA516 adapter to fit
into an LFBGA516 socket for an TC1798
• The DPR could be extended to 2 MByte per page.
4.2 Architecture
Fig. 4-1 "ETK-T2.2G Architecture" shows the block diagram of the ETK-T2.2G.
The connection to the ECU is made by an LFBGA connector.
Fig. 4-1 ETK-T2.2G Architecture
The microcontroller can read via the BGA connector from one of the two pages
of the data emulation memory and can write its data directly to the measure-
ment data memory. These two memories (data emulation memory, measure-
ment data memory) are using the same address space and are realized inside the
same DPRs. Through the BGA connector the microcontroller can communicate
with other external memories or peripheral components too. All microcontroller
signals are accessible on the BGA connector.
While the microcontroller accesses the program data (not the program code) out
of the data emulation memory, the content of the data emulation memory can
simultaneously be modified by the calibration and development system through
the serial ETK-interface. This process enables adjustments of parameters, charac-
teristic lines and maps through the calibration and development system. Using

ETAS Hardware Description
an additional measurement data memory area, the ECU microcontroller can send
data to the calibration and development system which receives, buffers and pro-
cesses this measured data. A flash memory is available for permanent storage of
the adjusted parameters (program data).
The 100 MBit/s serial interface provides communication with the calibration and
development system.
The ETK-T2.2G uses a 3 V technology. The power supply for the ETK-T2.2G is
provided by a switched power supply, to minimize power dissipation.
4.3 BGA Connector
The BGA connector interfaces the ETK-T2.2G with the ECU. All signals from the
inner ring of the microcontroller TC1798 are connected to the BGA connector
with some exceptions.
As the ECU target is prepared for the TC1791, all bonding differences and
incompatibilities between TC1791 and TC1798 have to be compensated. The
following exceptions are necessary to let the TC1798 run in a TC1791 are con-
nected to the BGA connector.
• All power supply lines are connected to their regarding planes in the inner
ring (Tab. 4-1 on page 17)
• All VAGND are connected together, VAREF3 is connected to VAREF2 (Tab.
4-2 on page 18)
• The fast A/D converter AN64 to AN71 are connected to AN24 to AN31
(Tab. 4-3 on page 18)
• Instead of the 21 data bus from the inner ring, 21 not used port pins from
the outer ring are connected to the BGA connector (Tab. 4-4 on page 19)

Also the clock signal must be provided through the connector to the microcon-
troller.
4.4 Microcontroller Interface
The whole microcontroller interface to the calibration and development system
memories has a 32 bit wide data bus and uses only one chip select for read and
write accesses.
The microcontroller can read and write its data directly from or to the data emu-
lation and measurement data memory. Fig. 4-2 on page 19 shows an overview
of the system with "on chip" Flash and RAM and external Flash and RAM mem-
ory. It also show the possibilities to access the different memories with its chip
selects. The chip select of the data emulation and measurement data memory
can be choosen (/CS1, /CS2, /CS3 or /CSCOMB) by soldering the respective
bridge on the PCB (see 4.15 "Chip Select Configuration Bridge").

ETAS Hardware Description
4.5 Data Emulation and Data Measurement
The complete data emulation and measurement data memory consists of two
1024 kByte pages (Fig. 4-3 "Data Emulation and Measurement Data Memory: 2
Pages with 1024 kByte each"). The address range of the used chip select to
address the data emulation and measurement memory must be 1024 kByte and
it must be defined at a 1024 kByte boundary.
Data emulation memory and measurement data memory must be located inside
this 1024 kByte address range. The segmentation of this address range between
both memory parts is variable. The measurement data memory and data emula-
tion memory can have variable size and offset addresses inside this fixed address
range.
4.5.1 Data Emulation Memory
During operation of the ECU, only program data, not program code, can be
modified by using the data emulation memory. Modification of program code
would inevitably lead to a system crash. The program code is continuously pro-
cessed out of the internal or external memory.
Fig. 4-3 Data Emulation and Measurement Data Memory: 2 Pages with
1024 kByte each
Reference data can be stored on one page ("Reference page") while the data on
the other page ("Working page") can be modified. It is possible to switch
between the two pages during operation through the application software.
4.5.2 Measurement Data Memory
The measurement data memory must be located within the address space of the
data emulation and measurement data memory. It can have variable size.
The measured data stored here can be transferred to the calibration and devel-
opment system via the serial ETK interface.
Note
Because there is no write protection of the data emulation memory possible,
care must be taken not to override emulation data.
