Product details
Overview
TC323LP16F160FAALXUMA1 from Infineon is a 16-bit automotive-qualified microcontroller with 160 kB Flash, 20 kB RAM, and integrated CAN FD controller. It operates at up to 160 MHz, supports ASIL-B functional safety compliance, and targets body control modules and gateway ECUs in 12 V vehicle architectures.
For engineers reviewing the TC323LP16F160FAALXUMA1 datasheet, TC323LP16F160FAALXUMA1 pinout, TC323LP16F160FAALXUMA1 application, or TC323LP16F160FAALXUMA1 equivalent, key selection criteria include Flash/RAM size, CAN FD channel count, ASIL-B certification status, and LQFP-64 package compatibility with PCB layout constraints.
Technical Context
This MCU implements a TriCore™ v1.6.2 CPU core with dual-issue pipeline and 5-stage execution. It integrates a Peripheral Server for deterministic I/O handling, a Multi-Channel DMA controller supporting scatter-gather transfers, and a System Memory Management Unit (SMMU) for memory protection.
The device includes a 12-bit SAR ADC with 24 channels, up to 6 FlexRay channels, 4 LIN interfaces, and 3 CAN FD controllers - one with time-triggered communication support compliant with ISO 11898-1:2015.
Key Specifications

Pinout & Package
LQFP-64 package with exposed thermal pad; RoHS-compliant, lead-free finish; JEDEC-standard footprint for automated placement and reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Core supply (1.3 V) | Power domain for CPU and digital logic; requires local low-ESR decoupling |
| VDDIO | I/O supply (3.3 V) | Supplies all GPIOs and peripheral interfaces; independent regulation improves noise immunity |
| RESETn | Active-low reset input | Asynchronous hardware reset with internal pull-up; compatible with external watchdog assertion |
| OSC_IN / OSC_OUT | Crystal oscillator terminals | Supports 1–20 MHz external crystal for precise clock generation and PLL reference |

| ADCTRIG0 | ADC conversion trigger input | Hardware-synchronized sampling via timer or peripheral event - eliminates software latency in sensor acquisition |
Key Features
| Feature | Design Value |
|---|---|
| Peripheral Server architecture | Offloads CPU from I/O polling via dedicated hardware scheduler - reduces interrupt latency and jitter in real-time tasks |
| Time-triggered CAN FD | Enables deterministic message scheduling per ISO 11898-1:2015 - critical for synchronized actuator control in gateways |
| Multi-Channel DMA | 64-channel controller with descriptor-based transfers - eliminates CPU involvement during large data moves (e.g., firmware updates over CAN) |
| SMMU with 8 regions | Configurable memory protection zones - isolates safety-critical code from application tasks per ASIL-B partitioning requirements |
| Embedded voltage regulator | On-die 1.3 V regulator for core supply - simplifies power design by reducing external component count |

FAQ
What is the maximum operating temperature range for TC323LP16F160FAALXUMA1?
The TC323LP16F160FAALXUMA1 is qualified for operation from −40 °C to +125 °C ambient temperature, meeting AEC-Q100 Grade 2 requirements. This range supports placement in engine bay-adjacent modules and under-hood ECUs where thermal stress exceeds standard industrial limits.
Does TC323LP16F160FAALXUMA1 support boot-from-Flash with secure boot?
Yes, it includes a Hardware Security Module (HSM) with AES-128, SHA-256, and RSA-2048 acceleration, enabling secure boot verification against signed firmware images stored in on-chip Flash. The HSM operates independently of the main CPU to prevent tampering during startup.
Can TC323LP16F160FAALXUMA1 be programmed via JTAG or DAP?
It supports both JTAG and Serial Wire Debug (SWD) interfaces using the standard ARM CoreSight debug architecture. SWD is preferred for production programming due to reduced pin count (2-wire), while JTAG remains available for full boundary-scan testing during board validation.
Is there an official evaluation board available for this part?
Yes - the KIT_AURIX_TC3XX_SK starter kit includes a TC323LP16F160FAALXUMA1-based board with CAN FD transceivers, LIN interface, debugging headers, and preloaded example firmware for quick validation of peripheral functionality and safety features.
