Overview
TC324LP16F160FAAKXUMA1 from Infineon is a 16-bit automotive microcontroller unit (MCU) based on the TriCore™ architecture, operating at 160 MHz, featuring 1.5 MB embedded Flash, 192 KB SRAM, and integrated CAN FD and LIN interfaces. It targets engine control units (ECUs) in gasoline and diesel powertrain systems.
For engineers reviewing the TC324LP16F160FAAKXUMA1 datasheet, TC324LP16F160FAAKXUMA1 pinout, TC324LP16F160FAAKXUMA1 application, or TC324LP16F160FAAKXUMA1 equivalent, key selection criteria include ASIL-B compliance, real-time interrupt latency ≤ 1.2 µs, Flash ECC protection, and dual-core lockstep support for safety-critical functions.
Technical Context
This MCU implements a TriCore™ V1.6.2 CPU core with MMU, supporting deterministic real-time execution and hardware-based memory protection. It integrates a Peripheral Control Unit (PCU) for autonomous peripheral management and a Safety Management Unit (SMU) with configurable error injection and diagnostic coverage monitoring.
The device includes a 12-bit SAR ADC with 48 channels, 4x GPT12 timers, and 2x SENT interfaces for sensor signal acquisition. Its communication stack supports up to 4 CAN FD channels (with bit rates up to 5 Mbit/s) and 2 LIN channels compliant with LIN 2.2A/ISO 17987-4.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TC334LP16F180FABKXUMA1 | Higher clock speed (180 MHz), 2 MB Flash, added Ethernet MAC - no additional CAN FD channels | Targeted at gateway ECUs requiring network bridging, not powertrain-specific real-time control | Select when Ethernet connectivity and larger code space outweigh cost and thermal constraints |
| TC275TP16F200NACXUMA1 | TriCore™ V1.6.1, 200 MHz, 2 MB Flash, but only 2 CAN FD channels and no SENT interface | Designed for chassis domain controllers; lacks torque-sensor analog front-end and SENT support | Prefer for brake-by-wire or ADAS sensor fusion where SENT and torque sensing are not required |
Compared with TC334LP16F180FABKXUMA1 and TC275TP16F200NACXUMA1, TC324LP16F160FAAKXUMA1 offers optimized balance of CAN FD bandwidth, SENT sensor interface, and thermal envelope for under-hood powertrain control - without over-provisioning Ethernet or unused Flash capacity.

FAQ
What is the maximum junction temperature rating for TC324LP16F160FAAKXUMA1?
The device is rated for a maximum junction temperature of 150 °C, validated per AEC-Q100 Grade 1 qualification. This allows operation in under-hood environments where ambient temperatures reach 125 °C, provided PCB thermal design maintains θJA ≤ 35 °C/W using the exposed thermal pad and 6-layer board stack-up with internal copper planes.
Does TC324LP16F160FAAKXUMA1 support bootloader updates over CAN FD?
Yes, it includes a ROM-based bootloader supporting secure firmware updates over CAN FD at up to 5 Mbit/s, with AES-128 encryption and signature verification using public-key infrastructure. The bootloader resides in immutable ROM and validates firmware images before writing to Flash sectors with ECC enabled.
How many independent PWM channels does TC324LP16F160FAAKXUMA1 provide for motor control?
The MCU provides 12 independent PWM channels via its GPT12 timer units, each configurable for center-aligned or edge-aligned output with dead-time insertion and fault input capture. These support three-phase inverter control for EPS and EGR stepper motors with synchronized ADC triggering on PWM zero-crossing events.
Is external RAM required for running AUTOSAR OS on TC324LP16F160FAAKXUMA1?
No, the integrated 192 KB SRAM with parity is sufficient to host AUTOSAR OS 4.3.x, including memory protection unit (MPU) configuration, scheduler stacks, and COM module buffers. External RAM is unnecessary unless custom middleware or large diagnostic log buffers are implemented beyond standard AUTOSAR configurations.
