Overview

XC2238N40F80LRABKXUMA1 from Infineon Technologies is a 16/32-bit single-chip microcontroller in the XC2000 Family Value Line, featuring an 80 MHz CPU clock (12.5 ns instruction cycle), 320 KB on-chip Flash memory, 16 KB PSRAM, and integrated MultiCAN Rev. 2.0B with up to 6 CAN nodes - deployed in automotive body control modules for real-time sensor actuation and networked ECU coordination.

For engineers reviewing the XC2238N40F80LRABKXUMA1 datasheet, XC2238N40F80LRABKXUMA1 pinout, XC2238N40F80LRABKXUMA1 application, or XC2238N40F80LRABKXUMA1 equivalent, key selection considerations include its 80 MHz C166-compatible CPU core, 64-pin LQFP package with 40 GPIOs, dual 10-bit ADCs (<1 µs conversion), CCU6x PWM units, and industrial-grade -40°C to 110°C operation.

Technical Context

The XC2238N40F80LRABKXUMA1 implements a five-stage pipelined C166-compatible CPU with MPU, supporting 16 Mbyte linear address space and fast context switching via two local register banks. It integrates a hardware CRC checker with programmable polynomial for memory integrity verification across SRAM and Flash regions.

Its peripheral set includes two synchronizable 10-bit ADCs (9 channels total), six USIC channels configurable as UART/LIN/SPI/I²C/IIS, and a MultiCAN module with 256 message objects - all coordinated by a Peripheral Event Controller enabling zero-wait-state, interrupt-driven data transfers using 24-bit address pointers.

FAQ

What is the maximum operating frequency and corresponding instruction cycle time?

The XC2238N40F80LRABKXUMA1 operates at a maximum CPU clock frequency of 80 MHz, delivering a 12.5 ns instruction cycle time. This is achieved using the on-chip PLL with external crystal input (1–20 MHz). All arithmetic instructions-including 32-bit addition and 16×16 multiplication-execute in one cycle under this clock configuration, as verified in Section 1.1 and Table 4.7.2.1 of the datasheet.

Does this microcontroller support CAN FD or only Classical CAN?

The XC2238N40F80LRABKXUMA1 implements MultiCAN Revision 2.0B only, supporting Classical CAN (up to 1 Mbit/s) with Full CAN and Basic CAN modes. It does not support CAN FD features such as flexible data rate or extended data length. CAN FD capability was introduced in later XC2000 derivatives like the XC2267 and TriCore-based TC2xx series.

How many independent PWM channels can be generated using CCU6x units?

The device integrates two CCU6x modules (CCU60 and CCU61), each providing three complementary PWM output pairs (6 total channels), with independent dead-time insertion, emergency shutdown inputs, and center-aligned modulation. These are fully hardware-controlled and do not require CPU intervention during runtime, as detailed in Section 3.8 of the datasheet.

Is there hardware support for memory integrity checking beyond Flash ECC?

Yes - in addition to Flash ECC, the XC2238N40F80LRABKXUMA1 includes a programmable hardware CRC checker supporting 8-, 16-, and 32-bit polynomials. It can verify arbitrary memory blocks (e.g., boot code in PSRAM, calibration tables in DSRAM) at startup or runtime, and is explicitly documented in Section 1.1 and Section 3.4 of the datasheet as a dedicated peripheral module.
