To access the ECU the FETK-T1.1 has to be connected via ES89x modules.
The system can be used for high speed Measurement, Calibration and ECU
flash programming. Support of high speed and high band width applications
e.g. functional prototyping - bypass depends on the functionality of the con

Features
3.3.1
General
• Enables highest possible data throughput by utilizing the microcontroller
“TRACE” interface e.g. AURORA for measurement purposes and the
debug interface for configuration and prototyping
• Gigabit Ethernet Interface:
– Connection to PC via ES89x modules
– Latency optimized proprietary Ethernet protocol for FETKs to ES89x
– Supports a variety of standard applications
• Calibration tool access performed via the microcontroller DAP interface
– 3.3
V DAP output levels, 5.0
V tolerant DAP input
– Configurable DAP interface mode and clock speed:
2-pin DAP mode (50
MHz, 100
MHz)
3-pin DAP mode, wide mode (100
MHz, 160
MHz)
• Permanent storage of configuration
• Third party MC-tool support via ES89x module possible
3.3.2
Measurement
• Fast measurements: ECU raster not faster than 15
µs
• Supports “turnkey mechanism” - measurement start immediately after
“Ignition on” and proceed measurement after ECU reset (only if serial
debug interface is using for measurement)
• Pin-less ECU handshake and trigger mechanism
• Hook-based (DISTAB) and hook-less measurement approaches

controller
• Working Page & Reference Page (2 page concept) realized by microcon
-
troller overlay mechanism
• Direct access to parameters, curves, and maps in internal RAM
• Microcontroller capability of internal Flash emulation can be used
