FX32K142HAT0MLHR operates at up to 112 MHz in HSRUN mode and 80 MHz in RUN mode. The 112 MHz frequency requires VDD ≥ 2.7 V and ambient temperature ≤ 105 °C (HSRUN thermal limit); above 105 °C, it must run at 80 MHz in RUN mode per thermal specifications. CSEc or EEPROM operations are prohibited at 112 MHz and require mode switch to RUN.
Does FX32K142HAT0MLHR support CAN-FD, and how many CAN interfaces does it have?
Yes, FX32K142HAT0MLHR supports CAN-FD through two FlexCAN modules. Each module is configurable for classical CAN or CAN-FD operation with bit rates up to 5 Mbps in FD mode. Both modules support message buffering, ID filtering, and loopback self-test - essential for automotive gateway and ECU applications.
