Product details
Overview
C164CI8E25MDBFXQMA1 from Infineon Technologies is a 16-bit single-chip microcontroller 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 an 8-channel 10-bit ADC with 7.8 µs conversion time. It targets industrial motor control and embedded automation systems requiring deterministic real-time response and integrated CAN communication.
For engineers reviewing the C164CI8E25MDBFXQMA1 datasheet, C164CI8E25MDBFXQMA1 pinout, C164CI8E25MDBFXQMA1 application, or C164CI8E25MDBFXQMA1 equivalent, key selection criteria include its 80 ns instruction cycle time, 3-timer unit with capture/compare (CAPCOM2/CAPCOM6), PLL-based clock generation (×1.5 to ×5), and 59 GPIO lines with selectable input thresholds - all in an 80-pin MQFP package.
Technical Context
The C164CI8E25MDBFXQMA1 implements a 4-stage pipelined C166-core CPU delivering 12.5 MIPS at 25 MHz, with hardware support for 16×16-bit multiply (400 ns) and 32÷16-bit divide (800 ns). Its memory architecture includes linear 16 MB address space, programmable external bus interface (4 MB), and on-chip bootstrap loader for in-system programming.
Peripheral integration centers on deterministic real-time control: CAPCOM6 provides 3/6 capture/compare channels plus 1 dedicated compare channel for flexible PWM generation; the 8-channel PEC enables single-cycle data transfers; and the dual serial channels support synchronous/asynchronous and high-speed synchronous protocols alongside the CAN controller.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit industrial microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-C164CI-8R25M | Same die, 64 KB ROM, identical peripherals and pinout; differs only in ROM content and marking | No functional difference - used where factory-programmed firmware is required instead of OTP | Select when firmware is finalized and volume production demands mask-ROM cost efficiency |
| C167CR-LM | Higher clock (40 MHz), 8 KB IRAM, no on-chip CAN; requires external CAN controller | Better compute throughput but increased BOM and layout complexity for CAN-enabled designs | Select only if >25 MHz performance is mandatory and CAN can be implemented externally |
Compared with SAK-C164CI-8R25M, this part offers identical functionality with field-programmable OTP instead of mask ROM; compared with C167CR-LM, it trades raw speed for integrated CAN and lower system-level design effort.

FAQ
What is the maximum operating frequency and corresponding instruction cycle time?
The C164CI8E25MDBFXQMA1 operates at up to 25 MHz with a 4-stage pipeline, achieving an 80 ns instruction cycle time. This timing is guaranteed under specified 5 V ±10% supply and industrial temperature range (–40°C to +85°C), enabling deterministic execution of real-time control loops.
Does this microcontroller support in-system programming (ISP)?
Yes - it includes an on-chip bootstrap loader accessible via serial interface (P3.10/P3.11), allowing firmware updates without external programming hardware. The OTP memory is programmed once during manufacturing; subsequent updates require reprogramming only if the device supports field reprogramming via the loader, which this variant does.
Is the CAN interface fully compliant with ISO 11898 and CAN 2.0B?
Yes - the integrated CAN controller implements full CAN 2.0B protocol compliance, supporting both standard (11-bit) and extended (29-bit) identifiers, 15 message objects with configurable acceptance filtering, and automatic retransmission. It requires an external CAN transceiver (e.g., TJA1040) for physical layer connection.
What are the power supply requirements and voltage tolerances?
The device requires a single 5 V ±10% supply (4.5 V to 5.5 V) for digital and analog sections, with separate VDD and VAGND pins. Analog reference voltage (VAREF) is internally derived from VDD and supports external override. No 3.3 V operation is supported - level-shifting is required for interfacing with modern low-voltage peripherals.
