Product details
Overview
C164CILMCAFXUMA1 from Infineon Technologies is a 16-bit single-chip microcontroller in the C166 family, featuring a 4-stage pipeline CPU, on-chip CAN 2.0B interface with 15 message objects, 2 KB IRAM, 2 KB XRAM, and 64 KB mask-programmed ROM. It operates at up to 25 MHz with 5 V supply and supports full-function CAPCOM6 for flexible PWM generation. Used in industrial motor control systems requiring integrated real-time communication and analog acquisition.
For engineers reviewing the C164CILMCAFXUMA1 datasheet, C164CILMCAFXUMA1 pinout, C164CILMCAFXUMA1 application, or C164CILMCAFXUMA1 equivalent, key selection criteria include CAN 2.0B compliance, 10-bit ADC conversion time down to 7.8 µs, 8-channel PEC support, PLL clock multiplication (1.5×–5×), and 80-pin MQFP package compatibility with legacy C164CI designs.
Technical Context
The C164CILMCAFXUMA1 implements a high-performance 16-bit CPU core with register-based architecture, single-cycle context switching, and 16 MByte linear address space. Its peripheral set includes a dedicated CAN controller compliant with ISO 11898-1 Rev. 2.0B, supporting both Full and Basic CAN modes with programmable message object arbitration.
Timing subsystems comprise three independent general-purpose timers, an oscillator watchdog, and a programmable PLL with selectable multiplication factors (1.5×, 2×, 2.5×, 3×, 4×, 5×). The A/D converter provides 8 channels with configurable sampling time and reference voltage inputs (VAREF/VAGND), while CAPCOM6 delivers 3/6 capture/compare channels plus one dedicated compare channel for multi-phase PWM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller with integrated CAN applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-C164CI-8R25M | Same die, 64 KB ROM, identical pinout and peripheral set; differs only in ROM content and ordering code suffix | No functional difference; used interchangeably where mask ROM programming matches target firmware | Select when firmware is finalized and mask ROM cost advantage outweighs OTP flexibility |
| SAK-C164CL-8R25M | Reduced-function CAPCOM6 (no CC6POSx inputs); otherwise identical memory, CAN, and timer resources | Limited PWM phase-shift capability; unsuitable for advanced motor control topologies requiring position-synchronized events | Choose for simpler timing tasks where full CAPCOM6 features are unused, enabling lower-cost derivative sourcing |
Compared with SAK-C164CI-8R25M, C164CILMCAFXUMA1 offers identical functionality but reflects Infineon's later ordering nomenclature; versus SAK-C164CL-8R25M, it retains full CAPCOM6 for precise multi-channel PWM synchronization required in servo drives.
