Features
3.2.1
General
• JTAG interface
– Configurable JTAG output levels: 3.3 V or 5.0 V
– Configurable JTAG interface clock speed: 10 MHz, 20 MHz, 25 MHz,
or 40 MHz
– JTAG signals available on the 40 pin Samtec connector
– Pinless startup protocol for FETK recognition and data acquisition
triggering
– Measurement raster down to 50
μ
s
• Enables highest possible data throughput by utilizing the microcontroller
“TRACE” interface e.g. AURORA trace for measurement purposes and
the debug interface for configuration and prototyping
– Support of Aurora interface clock speed for measurement: 1.25 GHz
– Aurora Trace Signals available on the 40 pin Samtec connector
– Measurement raster down to 10
μ
s
• Gigabit Ethernet Interface:
– Connection to PC via ES89x modules
– Latency optimized proprietary Ethernet protocol for FETKs to ES89x
– Supports a variety of standard applications
• “ETK Drivers and Tools” update to support ETAS software tools (INCA,
XCT)
• Firmware update (programming of the logic device) through HSP soft-
ware service packs; removal of FETK or ECU is not necessary
• Mounting possibilities inside or on top of ECU
• ECU flashing via FETK, Braindead flashing under ProF control
• Permanent storage of configuration in EEPROM
• Temperature range suitable for automotive applications
• Third party MC-tool support via ES89x module possible
• Supports “turnkey mechanism” - measurement start immediately after
“Ignition on” and proceed measurement after ECU reset (only if serial
debug interface is using for measurement)
• Hook-based (DISTAB) and hook-less measurement approaches
3.2.2
Calibration
• Concurrent use of calibration and measurement performed via micro-
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
• FETK powers Emulation RAM (for calibration purpose)
• Supports “Start on Any Page”
