FAQ
What is the maximum operating temperature range for TC334LP32F200FAALXUMA1?
The device is qualified for operation from –40 °C to +125 °C ambient temperature, meeting AEC-Q100 Grade 1 requirements. This rating applies to the full LQFP-176 package variant and is validated across all core, memory, and peripheral functions under sustained thermal stress conditions.
Does TC334LP32F200FAALXUMA1 support JTAG debugging?
Yes, it supports IEEE 1149.1 JTAG boundary scan and debug access via the DAP (Debug Access Port) interface. Debug functionality includes halt/resume control, breakpoint setting, and memory/register inspection, fully compatible with Infineon's iLLD and Aurix Development Studio toolchains.
How many CAN FD interfaces does TC334LP32F200FAALXUMA1 integrate?
The device integrates six independent CAN FD controllers compliant with ISO 11898-1:2015, each supporting data rates up to 5 Mbit/s and frame payloads up to 64 bytes. All six interfaces share dedicated message RAM and support flexible filtering, loopback testing, and error confinement modes.
Is TC334LP32F200FAALXUMA1 pin-compatible with other AURIX™ TC3xx devices?
It shares the same LQFP-176 footprint and pin assignment with TC332 and TC333 variants, enabling hardware reuse across safety-level variants. However, pin functions for HSM, TTC, and certain peripheral clocks differ - schematic and layout must be verified against the specific variant's pinout table.
