Product details
Overview
XC2238N40F80LAAKXUMA1 from Infineon Technologies is a 16/32-bit single-chip microcontroller in the XC2000 Family / Value Line, featuring a C166-compatible CPU with 80 MHz operation (12.5 ns instruction cycle), 320 KB on-chip Flash memory, 16 KB PSRAM, and integrated MultiCAN Rev. 2.0B interface with up to 256 message objects. It operates from 3.0 V to 5.5 V and targets automotive body control modules requiring deterministic real-time response.
For engineers reviewing the XC2238N40F80LAAKXUMA1 datasheet, XC2238N40F80LAAKXUMA1 pinout, XC2238N40F80LAAKXUMA1 application, or XC2238N40F80LAAKXUMA1 equivalent, key selection criteria include Flash ECC protection, dual-port RAM for concurrent access, CCU6x PWM timing precision, 10-bit ADC conversion time <1 µs, and JTAG/DAP debug support for safety-critical firmware validation.
Technical Context
The XC2238N40F80LAAKXUMA1 implements a five-stage pipelined C166 CPU core with MPU, supporting 16 Mbyte linear address space and fast context switching via two local register banks. Its memory subsystem includes ECC-protected Flash, SBRAM, DPRAM, and PSRAM - all accessible with single-cycle data transfer via Peripheral Event Controller (PEC).
Peripheral integration centers on deterministic real-time I/O: two synchronizable 10-bit ADCs with broken-wire detection, six serial channels (UART/LIN/SPI/I²C/IIS), six CAN nodes with hardware message filtering, and CCU6x units enabling high-resolution complementary PWM generation with dead-time insertion for motor control.

FAQ
What is the maximum operating temperature range for XC2238N40F80LAAKXUMA1?
The XC2238N40F80LAAKXUMA1 is rated for operation from -40°C to +125°C, as indicated by the "LAA" suffix in the ordering code (SAK-temperature grade). This rating is validated per Infineon's qualification standards for automotive applications and includes full functionality of Flash, RAM, ADC, and CAN modules across the range.
Does XC2238N40F80LAAKXUMA1 support in-system programming via CAN?
Yes - the device includes an on-chip bootstrap loader that supports firmware updates over CAN using standardized UDS (ISO 14229) diagnostic services. The bootloader resides in protected ROM and validates Flash write operations using CRC before committing, ensuring update integrity even during power interruption.
How many independent CAN nodes does the MultiCAN module support?
The MultiCAN module in XC2238N40F80LAAKXUMA1 supports up to six independent CAN nodes, each configurable as Full CAN or Basic CAN. Each node has dedicated message object RAM (up to 256 total objects), hardware acceptance filtering, and automatic retransmission - enabling simultaneous communication with multiple vehicle domains without CPU intervention.
Is the 8 KB stand-by RAM (SBRAM) retained during STOP mode?
Yes - the 8 KB SBRAM retains full data content during STOP mode, powered by the VBAT supply (typically 3.0–5.5 V). This enables rapid wake-up with preserved context for RTC alarms, CAN wake events, or GPIO interrupts, reducing restart latency to under 5 µs while consuming <10 µA typical current.
