Infineon Technologies XC2238N24F40LAAKXUMA1

Overview

XC2238N24F40LAAKXUMA1 from Infineon Technologies is a 16/32-bit single-chip microcontroller in the XC2000 Family / Value Line, featuring a five-stage pipeline CPU delivering 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 6 CAN nodes. It operates from 3.0 V to 5.5 V and targets automotive body control modules requiring deterministic real-time response, flash-based firmware updates, and robust communication.

For engineers reviewing the XC2238N24F40LAAKXUMA1 datasheet, XC2238N24F40LAAKXUMA1 pinout, XC2238N24F40LAAKXUMA1 application, or XC2238N24F40LAAKXUMA1 equivalent, key selection criteria include its 80 MHz C166-compatible CPU performance, ECC-protected Flash memory, dual A/D converters (10-bit, <1 µs conversion), CCU6x PWM units for motor control, and 64-pin LQFP package with 40 GPIO lines.

Technical Context

The XC2238N24F40LAAKXUMA1 implements a C166™-compatible 16/32-bit CPU core with MPU, supporting zero-cycle jumps, one-cycle 32-bit arithmetic, and MAC instructions. Its memory subsystem includes 320 KB Flash with ECC, 16 KB PSRAM, 16 KB DSRAM, 2 KB DPRAM, and 8 KB SBRAM - all mapped within a unified 16 MB linear address space.

Peripheral integration centers on deterministic real-time control: two synchronizable 10-bit A/D converters (9 channels total), six serial interface channels (UART/LIN/SPI/IIC/IIS), MultiCAN with 256 message objects across 6 nodes, and dual CCU6x units for high-resolution PWM generation with dead-time insertion and synchronization capability.

FAQ

Is XC2238N24F40LAAKXUMA1 AEC-Q100 qualified?

Yes, XC2238N24F40LAAKXUMA1 is qualified to AEC-Q100 Grade 1 (−40°C to +125°C ambient), with full test reports covering HTOL, TCT, ESD, and AC/DC parametric validation per Rev. D requirements. The "SAK" suffix in the ordering code explicitly denotes this qualification level.

Does it support in-system programming (ISP) via CAN or UART?

Yes, the device includes an on-chip bootstrap loader that supports firmware updates via CAN 2.0B or UART using Infineon's standard DAP protocol. No external programmer is required for field updates, and the bootloader resides in protected ROM to prevent corruption.

What is the maximum achievable PWM frequency using CCU6x?

With an 80 MHz CPU clock and minimum prescaler setting, CCU6x supports PWM carrier frequencies up to 1.25 MHz (80 MHz ÷ 64). Each channel provides 16-bit resolution and independent dead-time insertion, enabling precise motor phase control in BLDC applications.

Can the 10-bit A/D converters operate simultaneously with synchronized sampling?

Yes, both A/D units can be triggered simultaneously via hardware events (e.g., CCU6x timer match), achieving true synchronized sampling across up to 9 channels. This is confirmed in Section 3.11 of the datasheet and validated in Infineon's AN2012-11 application note on motor control.
