Overview
C164CM4EFABKXUMA1 from Infineon Technologies is a 16-bit single-chip microcontroller in the C166 family, featuring a 4-stage pipeline CPU, 32 KB on-chip OTP program memory, 2 KB internal RAM, integrated CAN 2.0B interface with 15 message objects, and 10-bit A/D converter with 7.8 µs minimum conversion time - deployed in industrial motor control and automotive body electronics.
For engineers reviewing the C164CM4EFABKXUMA1 datasheet, C164CM4EFABKXUMA1 pinout, C164CM4EFABKXUMA1 application, or C164CM4EFABKXUMA1 equivalent, key selection criteria include OTP programmability, CAN 2.0B compliance, 20 MHz max operating frequency, 64-pin TQFP package, and peripheral integration including CAPCOM6 PWM unit and PEC-driven DMA.
Technical Context
The C164CM4EFABKXUMA1 implements a register-based 16-bit CPU with single-cycle context switching support and 16 MByte linear address space. Its on-chip PLL supports clock multiplication factors of 1.5× to 5×, enabling flexible system timing from external crystal or oscillator inputs.
It integrates dual serial interfaces (asynchronous/synchronous/HS-synchronous), a real-time clock, and a 12-channel CAPCOM2 unit plus dedicated CAPCOM6 for multi-phase PWM generation - all managed via a 32-source, 16-priority interrupt system with 40 ns sample rate.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-C164CM-4R25F | 32 KB mask ROM instead of OTP; 25 MHz max frequency | Fixed firmware only; higher performance but no field updates | Select when production volume justifies mask ROM NRE and speed >20 MHz is required |
| C167CR-LM | Enhanced C167 core, 64 KB flash, 2x CAN, 12-bit ADC | Higher integration, flash-based reprogramming, extended temperature grade | Select for new designs requiring flash flexibility, dual CAN, or extended temp operation |
Compared with SAK-C164CM-4R25F and C167CR-LM, the C164CM4EFABKXUMA1 offers field-programmable OTP at 20 MHz with proven CAN 2.0B implementation - balancing cost, update capability, and industrial reliability where flash endurance or dual CAN are not mandatory.
