Product details
Overview
C164CI8EMDBFXQMA1 from Infineon Technologies is a 16-bit single-chip microcontroller in the C166 family, featuring an on-chip 64 KB OTP program memory, full-function CAN 2.0B interface with 15 message objects, 2 KB IRAM + 2 KB XRAM, and operation up to 25 MHz at 5 V supply. It integrates CAPCOM6 for flexible PWM generation, an 8-channel 10-bit ADC (7.8 µs conversion), three general-purpose timers, dual serial channels, and real-time clock functionality - deployed in industrial motor control and automotive body electronics.
For engineers reviewing the C164CI8EMDBFXQMA1 datasheet, C164CI8EMDBFXQMA1 pinout, C164CI8EMDBFXQMA1 application, or C164CI8EMDBFXQMA1 equivalent, key selection criteria include OTP-based field-programmability, full CAN 2.0B support with dedicated message RAM, 80 ns instruction cycle time, and 80-pin MQFP package compatibility with legacy C164CI-8R/8EM designs.
Technical Context
The C164CI8EMDBFXQMA1 implements a 4-stage pipelined 16-bit CPU delivering 12.5 MIPS at 25 MHz, with register-based architecture enabling single-cycle context switching and 16 MByte linear address space. Its peripheral event controller (PEC) supports interrupt-driven single-cycle data transfers across eight channels.
On-chip clock generation uses a programmable PLL (1.5× to 5× multiplication), prescaler, or direct external clock input; power management includes Idle, Sleep, and Power Down modes with oscillator watchdog and programmable watchdog timer. The CAN module complies with ISO 11898 and supports both Full CAN and Basic CAN operation.

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-C164CI-8R25M | 64 KB mask ROM instead of OTP; identical pinout, peripherals, and CAN functionality | Fixed firmware only; no field updates possible - suitable for high-volume, stable-code deployments | Select when firmware is finalized and volume justifies mask cost; avoid if calibration or regional variants needed |
| SAK-C164CL-8R25M | Reduced-function CAPCOM6 (no CC16–CC19 outputs); otherwise identical memory, CAN, and timer resources | Limited PWM channel count restricts use in multi-phase motor control requiring >3 independent outputs | Select only for simpler timing tasks (e.g., LED dimming, fan control) where full CAPCOM6 is unnecessary |
Compared with SAK-C164CI-8R25M and SAK-C164CL-8R25M, the C164CI8EMDBFXQMA1 uniquely combines field-programmable OTP with full CAPCOM6 and CAN 2.0B - making it optimal for prototyping, low-to-mid volume production, and applications requiring post-deployment firmware adaptation.

FAQ
Does C164CI8EMDBFXQMA1 support in-system programming (ISP) via UART?
Yes. The device includes an on-chip bootstrap loader that enables UART-based in-system programming without external hardware programmers. Firmware updates are performed using standard serial communication with predefined command sequences defined in Infineon Application Note AP32012, supporting both code and configuration data writes to OTP memory.
What is the maximum operating frequency and corresponding instruction throughput?
The C164CI8EMDBFXQMA1 operates at up to 25 MHz CPU clock, achieving 12.5 million instructions per second (MIPS) with an 80 ns instruction cycle time. This performance level is sustained across the full industrial temperature range (–40°C to +85°C) under 5.0 V ±10% supply conditions.
How many CAN message objects are implemented, and are they fully configurable?
The device implements 15 dedicated CAN message objects in hardware, each independently configurable for transmit/receive mode, identifier masking, FIFO behavior, and interrupt generation. All objects support standard (11-bit) and extended (29-bit) identifiers per ISO 11898-1, with automatic retransmission and error confinement.
Is the 10-bit ADC capable of simultaneous sampling across all 8 channels?
No. The 8-channel 10-bit ADC uses a single SAR converter with multiplexed inputs; channels are sampled sequentially. Minimum conversion time is 7.8 µs per channel, and total 8-channel scan time is ≤62.4 µs. Simultaneous sampling requires external analog front-end hardware or higher-end derivatives like C167CS.
