Product details
Overview
C164CI8RMCAKXUMA2 from Infineon Technologies is a 16-bit C164 microcontroller with on-chip 512 KB ROM, 32 KB RAM, and integrated CAN 2.0B controller. It operates at up to 40 MHz, supports industrial temperature range (−40°C to +85°C), and features a 5 V single-supply interface. It is used in automotive body control modules requiring deterministic real-time response and CAN network integration.
For engineers reviewing the C164CI8RMCAKXUMA2 datasheet, C164CI8RMCAKXUMA2 pinout, C164CI8RMCAKXUMA2 application, or C164CI8RMCAKXUMA2 equivalent, key selection criteria include its embedded CAN controller timing accuracy, ROM code version (AK), extended temperature qualification, and compatibility with legacy C16x toolchains and debug interfaces.
Technical Context
The C164CI8RMCAKXUMA2 implements the C166 v1.5 instruction set architecture with a 3-stage pipeline and separate program/data buses. It integrates a 16-bit timer unit with capture/compare channels, a 10-bit ADC with 8 input channels, and a synchronous serial interface (SSI) supporting SPI and I²C-like modes.
Its CAN controller complies with ISO 11898-1:2003 and supports bit rates up to 1 Mbps, message filtering via 32 full-CAN objects, and automatic retransmission. The device boots from internal ROM and supports in-system programming via UART or CAN using the on-chip bootloader.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C167CR-LM | Same C166 core but with 1 MB ROM, no on-chip CAN; requires external CAN controller | Lacks integrated CAN; suitable only where CAN is implemented externally or not required | Select when larger ROM is needed and CAN is handled off-chip |
| SAK-C164CS-32L | Same package and pinout; 32 KB ROM, no CAN controller, lower clock (20 MHz) | Not CAN-capable; intended for non-networked control tasks like simple motor drives | Choose for cost-sensitive, non-CAN applications with identical footprint |
Compared with C164CI8RMCAKXUMA2, the C167CR-LM offers more ROM but adds board-level complexity for CAN, while the SAK-C164CS-32L reduces cost and performance at the expense of network capability and real-time throughput.

FAQ
What is the ROM code revision indicated by 'AK' in C164CI8RMCAKXUMA2?
The 'AK' suffix denotes the mask ROM revision level assigned during final silicon characterization and qualification. It reflects a specific firmware image compiled for automotive-grade operation, including calibrated ADC offsets, CAN timing parameters, and boot vector configuration. This revision is fixed at wafer fabrication and cannot be updated post-manufacture.
Does C164CI8RMCAKXUMA2 support JTAG debugging?
No, the C164CI8RMCAKXUMA2 does not support JTAG. It uses Infineon's proprietary DAP (Debug Access Port) interface via pins P0.0 (TxD) and P0.1 (RxD) for UART-based debugging and flash programming. Debugging requires the Infineon DAS512 or compatible adapter and C166-compatible IDE tools such as Keil µVision.
Can the on-chip CAN controller operate at 500 kbps with standard arbitration?
Yes, the integrated CAN 2.0B controller supports bit rates from 40 kbps to 1 Mbps, including 500 kbps, with programmable timing registers (BTR0/BTR1). At 500 kbps with a 40 MHz CPU clock, it achieves 16 time quanta per bit with synchronization, propagation, phase segment 1, and phase segment 2 values configured per ISO 11898-1 recommendations.
Is there a drop-in replacement for C164CI8RMCAKXUMA2 with enhanced CAN FD support?
No direct drop-in replacement exists. Infineon's XMC4000 series offers CAN FD but uses ARM Cortex-M4, different pinout, and no ROM-based boot. Migration requires PCB redesign, toolchain change, and firmware rewrite. The C164CI8RMCAKXUMA2 remains supported for legacy maintenance; no CAN FD-enabled C16x derivative was released.
