Product details
Overview
C164CI8EMCBFXUMA1 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, and a PLL-based clock generator supporting up to 25 MHz operation. It integrates 4 KB on-chip RAM (2 KB IRAM + 2 KB XRAM), an 8-channel 10-bit ADC (7.8 µs min conversion time), CAPCOM2/CAPCOM6 PWM units, three general-purpose timers, two serial channels, and a real-time clock - deployed in industrial motor control and automotive body electronics.
For engineers reviewing the C164CI8EMCBFXUMA1 datasheet, C164CI8EMCBFXUMA1 pinout, C164CI8EMCBFXUMA1 application, or C164CI8EMCBFXUMA1 equivalent, key selection considerations include OTP memory configurability, full CAN 2.0B compliance, 80 ns instruction cycle timing at 25 MHz, and support for single-cycle context switching in real-time deterministic firmware.
Technical Context
The C164CI8EMCBFXUMA1 implements a 4-stage pipelined 16-bit CPU with register-based architecture, enabling 12.5 MIPS at 25 MHz and hardware-accelerated 16×16 multiply (400 ns) and 32÷16 divide (800 ns). Its interrupt system supports 32 sources across 16 priority levels with 40 ns sample rate, coordinated via a Peripheral Event Controller (PEC) for zero-overhead data transfers.
On-chip peripherals include a full-function CAPCOM6 unit (3/6 capture/compare channels + 1 compare channel) for flexible PWM generation, a dedicated CAN controller licensed from Robert Bosch GmbH (Rev. 2.0B active), and programmable external bus interface supporting up to 4 MB address space with multiplexed/demultiplexed 8-/16-bit data paths and four chip-select signals.

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 peripheral set and pinout | Fixed firmware only; no field updates possible | Select when production volume justifies ROM NRE cost and firmware is fully validated |
| C167CR-LM | Enhanced C166 core (100 MHz max), 128 KB flash, but no integrated CAN controller | Requires external CAN transceiver and protocol stack implementation | Select when higher CPU throughput is needed and CAN can be implemented externally |
Compared with SAK-C164CI-8R25M and C167CR-LM, the C164CI8EMCBFXUMA1 uniquely balances OTP flexibility, integrated CAN 2.0B, and deterministic real-time performance - making it optimal for mid-volume automotive and industrial control where firmware iteration and bus integration are both essential.

FAQ
What is the maximum guaranteed operating frequency for C164CI8EMCBFXUMA1?
The device is rated for up to 25 MHz CPU clock with PLL enabled, delivering an 80 ns instruction cycle time. This frequency is fully characterized across the industrial temperature range (–40°C to +85°C) and supported by all on-chip peripherals including CAN, ADC, and timers without derating.
Does C164CI8EMCBFXUMA1 support in-system programming of its OTP memory?
No - the 64 KB OTP memory must be programmed once during final test using Infineon's dedicated programming equipment (e.g., Data I/O PS-290). Unlike flash devices, it does not support in-circuit reprogramming; however, the on-chip bootstrap loader enables firmware updates via serial interface to RAM-executed code.
How many CAN message objects are implemented, and are they configurable?
The device implements 15 dedicated message objects in its on-chip CAN controller, each independently configurable for ID masking, direction (TX/RX), and acceptance filtering. All objects support full CAN 2.0B functionality including extended identifiers and remote frame handling - no software arbitration required.
Is the C164CI8EMCBFXUMA1 qualified for automotive applications per AEC-Q100?
No - this specific variant (C164CI8EMCBFXUMA1) is specified for industrial temperature range (–40°C to +85°C) and lacks AEC-Q100 qualification documentation. For automotive use, Infineon offers the SAK-C164CI-8R25M derivative with automotive-grade screening and qualification reports available upon request.
