Infineon Technologies XC2361E136F128LAAKXUMA1

Overview

XC2361E136F128LAAKXUMA1 from Infineon Technologies is a 32-bit TriCore™ microcontroller featuring 128 KB Flash, 16 KB RAM, and integrated CAN 2.0B controller, designed for real-time automotive body control modules requiring deterministic interrupt response and ASIL-B capable safety features.

For engineers reviewing the XC2361E136F128LAAKXUMA1 datasheet, XC2361E136F128LAAKXUMA1 pinout, XC2361E136F128LAAKXUMA1 application, or XC2361E136F128LAAKXUMA1 equivalent, key selection criteria include Flash endurance (100k write/erase cycles), on-chip debug support via DAP interface, CAN bus timing accuracy (±1% at 8 MHz), and qualification to AEC-Q100 Grade 2 (−40 °C to +105 °C).

Technical Context

This MCU implements the TriCore V1.6.1 architecture with a 3-stage pipeline, supporting both real-time control and embedded software execution. It integrates a Peripheral Event Controller (PEC) for autonomous DMA-like peripheral coordination and a System Timer (STM) with 32-bit resolution and programmable prescaler.

The device includes a 12-bit SAR ADC with 16 channels, conversion time ≤1.2 μs, and hardware-triggered sequencing. Its power management unit supports five low-power modes (Standby, Sleep, Idle, Power-down, and Deep Power-down), with wake-up latency as low as 1.5 μs from Sleep mode.

Key Specifications

Pinout & Package

FAQ

What debug interface does XC2361E136F128LAAKXUMA1 support?

XC2361E136F128LAAKXUMA1 supports both JTAG and DAP (Debug Access Port) interfaces via dedicated pins (TCK/TMS/TDI/TDO/TRST). It is fully compatible with Infineon's DAS-2 debugger and third-party tools like Lauterbach TRACE32, enabling real-time tracing, flash programming, and breakpoint debugging without halting peripheral operation.

Is XC2361E136F128LAAKXUMA1 qualified for automotive use?

Yes - it is AEC-Q100 qualified to Grade 2 (−40 °C to +105 °C ambient), with built-in safety mechanisms including Flash ECC, RAM parity, watchdog timers, and voltage monitoring. It supports ISO 26262 ASIL-B development workflows through documented FMEDA reports and safety manual availability from Infineon.

Does this MCU include hardware CRC calculation?

Yes - it integrates a dedicated CRC unit compliant with CRC-32 IEEE 802.3, supporting both memory checksum verification and message integrity checking for CAN frames. The unit operates independently of the CPU and can process up to 32 bits per clock cycle, reducing firmware overhead in safety-critical data validation.

Can XC2361E136F128LAAKXUMA1 operate without external crystal?

Yes - it includes an internal RC oscillator (10 MHz ±2%) usable for boot and low-speed operation. However, for CAN timing compliance (±1% tolerance), an external 8 MHz crystal is required. The device supports automatic failover to internal RC if the crystal fails, maintaining basic functionality with degraded timing accuracy.
