Product details
Overview
C164SL8R25MCAHXUMA1 from Infineon Technologies is a 16-bit C16x microcontroller with 25 MHz CPU clock, 128 KB on-chip ROM, 8 KB RAM, and integrated CAN 2.0B controller. It targets automotive body electronics and industrial control systems requiring deterministic real-time response, embedded diagnostics, and robust serial communication.
For engineers reviewing the C164SL8R25MCAHXUMA1 datasheet, C164SL8R25MCAHXUMA1 pinout, C164SL8R25MCAHXUMA1 application, or C164SL8R25MCAHXUMA1 equivalent, key selection criteria include its 25 MHz instruction throughput, 5 V tolerant I/O, on-chip boot loader, CAN message object handling capability, and extended temperature range support (–40 °C to +125 °C).
Technical Context
The C164SL8R25MCAHXUMA1 implements the C166 v1.5 architecture with register-based ALU, 16-bit data bus, and 24-bit address space. It integrates a 16-channel general-purpose timer unit, 8-channel ADC with 10-bit resolution and 12.5 µs conversion time, and a synchronous serial interface (SSI) supporting SPI and TI formats.
Its CAN controller supports full CAN 2.0B protocol compliance with 16 message objects, programmable acceptance filtering, and automatic retransmission. The device uses a single 5 V supply and includes power management modes (idle, standby, stop) with wake-up via external interrupt or CAN activity.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C167CR-LM | Same C166 core, 40 MHz max clock, 256 KB ROM, 16 KB RAM, but lacks integrated CAN controller | Requires external CAN transceiver + controller IC; higher performance but larger BOM and layout footprint | Select when higher CPU throughput and memory are critical, and CAN can be added externally |
| XC2267M-104F80L | Successor generation (TriCore), 80 MHz, 1 MB flash, integrated CAN FD, but requires different toolchain and migration effort | Supports CAN FD data rates and advanced safety features (ASIL-D), but not drop-in compatible | Select for new designs targeting future-proof CAN FD and functional safety certification |
Compared with C167CR-LM and XC2267M-104F80L, the C164SL8R25MCAHXUMA1 offers optimal balance of CAN integration, temperature rating, and legacy toolchain compatibility for cost-sensitive automotive body control modules where CAN 2.0B suffices.

FAQ
Is C164SL8R25MCAHXUMA1 pin-compatible with other C164 variants?
No. While sharing the PLCC-84 footprint with some C164 derivatives, pin assignments for peripherals like CANRX/CANTX, ADC channels, and timer outputs differ across mask ROM versions. Pin mapping must be verified against the specific variant's datasheet - C164SL8R25MCAHXUMA1 uses dedicated CAN pins at P3.0/P3.1 and ADC inputs on P2.0–P2.7.
Does this MCU support JTAG debugging?
No. C164SL8R25MCAHXUMA1 does not include JTAG or OCDS debug interface. Debugging relies on Infineon's proprietary DAP (Debug Access Port) via UART using the on-chip boot loader, or external ICE tools compatible with C166 v1.5 architecture.
What is the maximum operating frequency of the internal oscillator?
The internal oscillator is not user-configurable as a standalone clock source. The device requires an external crystal or ceramic resonator connected to XTAL1/XTAL2. Maximum supported frequency is 25 MHz, matching the rated CPU clock; higher frequencies risk timing violation and are not guaranteed.
Can the on-chip ROM be reprogrammed in-circuit?
No. C164SL8R25MCAHXUMA1 uses mask-programmed ROM, which is permanently written during fabrication. Firmware updates require replacing the device or using the UART/CAN boot loader to load application code into RAM only - no flash or EEPROM is present for persistent storage.
