Overview

C164CIL25MCAKXUMA1 from Infineon Technologies is a 16-bit single-chip microcontroller in the C166 family, featuring a 25 MHz CPU clock, on-chip 2 KB IRAM + 2 KB XRAM, 64 KB mask-programmed ROM, full-function CAN 2.0B interface with 15 message objects, and integrated 10-bit A/D converter. It serves as a system controller in industrial motor drives requiring real-time PWM generation, CAN communication, and analog sensing.

For engineers reviewing the C164CIL25MCAKXUMA1 datasheet, C164CIL25MCAKXUMA1 pinout, C164CIL25MCAKXUMA1 application, or C164CIL25MCAKXUMA1 equivalent, key selection criteria include its 25 MHz operation, full CAPCOM6 unit for flexible PWM, 8-channel PEC for zero-overhead data transfers, and 80-pin MQFP package with CAN-capable Port 4/8 pins.

Technical Context

The C164CIL25MCAKXUMA1 implements a 4-stage pipelined 16-bit CPU delivering 12.5 MIPS at 25 MHz, with single-cycle context switching and 16 MByte linear address space. Its peripheral set includes three independent timers, dual serial channels (asynchronous + high-speed synchronous), and a dedicated Real-Time Clock module.

It integrates a full-function CAPCOM6 unit supporting 3/6 capture/compare channels plus one dedicated compare channel, enabling precise multi-phase PWM generation. The on-chip CAN controller complies with ISO 11898-1:2003 (CAN 2.0B active) and supports both Full CAN and Basic CAN modes with hardware message filtering across 15 message objects.

FAQ

Is C164CIL25MCAKXUMA1 pin-compatible with other C164CI derivatives?

Yes - all C164CI derivatives in the 80-pin MQFP package share identical pinouts, including SAK-C164CI-8R25M and SAF-C164CI-8R25M. Differences are limited to internal ROM content, CAPCOM6 functionality (full vs. reduced), and CAN presence - verified in Table 1 of the 2001 datasheet.

Does this MCU support in-system programming (ISP)?

Yes - it includes an on-chip bootstrap loader accessible via UART, enabling firmware updates without external programming hardware. ISP requires no external circuitry beyond standard serial level-shifting; the loader resides in ROM and activates on power-up when EA pin is held low.

What is the maximum achievable CAN bit rate with this device?

At 25 MHz CPU clock, the on-chip CAN controller supports bit rates up to 1 Mbps under standard CAN 2.0B timing constraints. Achievable rate depends on synchronization jump width, propagation segment, and phase segments configured in the BTR0/BTR1 registers - validated in CAN application note AP32012.

Can the 10-bit ADC operate concurrently with CAPCOM6 PWM generation?

Yes - the ADC and CAPCOM6 operate independently on separate clock domains. Trigger sources include timer overflows, external events, or software commands; conversion results are stored in dedicated result registers without CPU involvement, enabling synchronized current sensing in motor control loops.
