FAQ
What is the maximum operating temperature range for TC1782N320F180HRBAKXUMA1?
The device is qualified for operation from –40°C to +125°C ambient temperature per AEC-Q100 Grade 1 requirements. All electrical parameters-including 180 MHz CPU clock, flash read/write timing, and FlexRay ERAY_PLL jitter-are guaranteed across this full range, with thermal derating applied only above 105°C junction temperature.
Does TC1782N320F180HRBAKXUMA1 support JTAG debugging and real-time trace?
Yes. The part includes IEEE 1149.1-compliant JTAG pins (TRST, TCK, TMS, TDI, TDO) and a Debug Access Port (DAP) supporting real-time instruction and data trace via Infineon's iLLD library and TRACE32 debug tools. Trace bandwidth supports full-speed streaming at 180 MHz CPU operation.
How is EEPROM functionality implemented on this microcontroller?
EEPROM emulation is provided by the 128 KB Data Flash (DFLASH), which supports 100,000 write/erase cycles and byte-wise programming. Infineon's Flash API (FLS) handles wear leveling, error correction, and atomic update operations-enabling reliable non-volatile storage for calibration data, fault logs, and adaptive parameters without external EEPROM.
Is the TC1782N320F180HRBAKXUMA1 pin-compatible with other TC17xx devices?
No. TC1782N320F180HRBAKXUMA1 uses the PG-LQFP-176-21 package and is not pin-compatible with earlier TC1766 or TC1796 variants due to differences in peripheral mapping, power pin distribution, and FlexRay signal routing. Migration requires PCB redesign and firmware adaptation for peripheral register offsets.
