For engineers reviewing the C164CI8E25MDBKXQMA1 datasheet, C164CI8E25MDBKXQMA1 pinout, C164CI8E25MDBKXQMA1 application, or C164CI8E25MDBKXQMA1 equivalent, key selection criteria include CAN 2.0B compliance, 10-bit 8-channel ADC with 7.8 µs conversion time, 3-timer unit, PLL-based clock generation (×1.5 to ×5), and 80-pin MQFP package with 0.65 mm pitch.
Technical Context
The C164CI8E25MDBKXQMA1 implements a 4-stage pipelined 16-bit CPU delivering 12.5 MIPS at 25 MHz, with single-cycle context switching, 16 MByte linear address space, and register-based architecture supporting HLL and RTOS. Its peripheral set includes dual serial channels (asynchronous/synchronous/HS-sync), on-chip RTC, and programmable watchdog with oscillator watchdog.
It integrates a full-function CAPCOM6 unit (3/6 capture/compare + 1 compare channel) for flexible PWM generation, an 8-channel 10-bit ADC with programmable sampling down to 7.8 µs, and 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 CAN microcontroller 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; intended for production with fixed firmware image | Select when firmware is finalized and mask ROM cost advantage outweighs field reprogrammability |
| SAF-C164CI-L25M | ROM-less derivative with external memory interface enabled; lacks on-chip 64 KB ROM but retains full CAN, CAPCOM6, and ADC | Requires external Flash/ROM; suitable for prototyping or designs needing firmware updates | Select when iterative firmware development or field upgrades are required; verify external memory timing constraints |
Compared with SAK-C164CI-8R25M, C164CI8E25MDBKXQMA1 offers identical functionality but uses Infineon's standardized ordering code format indicating MQFP packaging, extended temperature range, and automotive qualification (QMA1 suffix); versus SAF-C164CI-L25M, it trades external memory flexibility for lower BOM count and deterministic boot time.

FAQ
What is the maximum guaranteed operating frequency for C164CI8E25MDBKXQMA1?
The device is fully specified and tested for operation at 25 MHz CPU clock frequency. This is achieved using the internal PLL with multiplication factors up to ×5 from a 5 MHz crystal, or direct 25 MHz external clock. Operation above 25 MHz violates datasheet limits and may cause timing violations in the 4-stage pipeline.
Does C164CI8E25MDBKXQMA1 support in-system programming (ISP)?
Yes - it includes an on-chip bootstrap loader accessible via UART0 (P3.10/P3.11). Firmware updates can be performed using standard serial communication without external programming hardware, provided the EA pin is held high during reset to activate the bootloader.
How many CAN message objects are implemented, and are they configurable?
The device implements 15 dedicated CAN message objects, each independently configurable for transmit/receive, identifier masking, FIFO behavior, and priority. All 15 objects are accessible via the CAN controller's object RAM and support full CAN 2.0B functionality including extended identifiers and remote frames.
Is the on-chip ADC synchronized with PWM events?
Yes - the 10-bit ADC supports hardware trigger synchronization with CAPCOM6 PWM events (e.g., center-aligned PWM zero-crossing or period end), enabling precise current sampling in motor control applications. Trigger source selection is configured via the ADC control register (ADCSCON).
