Product details
Overview
C164CI8EMCBFXQMA1 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 operation up to 25 MHz at 5 V supply. It integrates 2 KB IRAM, 2 KB XRAM, an 8-channel 10-bit ADC (7.8 µs conversion), CAPCOM2/6 units for PWM and capture/compare, and a 3-timer unit-used in industrial motor control and embedded automation systems.
For engineers reviewing the C164CI8EMCBFXQMA1 datasheet, C164CI8EMCBFXQMA1 pinout, C164CI8EMCBFXQMA1 application, or C164CI8EMCBFXQMA1 equivalent, key selection criteria include CAN 2.0B compliance, OTP programmability, 80-pin MQFP package compatibility, 16-priority interrupt latency down to 40 ns, and support for external bus expansion up to 4 MB.
Technical Context
The C164CI8EMCBFXQMA1 implements a 4-stage pipelined 16-bit CPU delivering 12.5 MIPS at 25 MHz, with single-cycle context switching and register-based architecture optimized for real-time OS execution. Its peripheral event controller (PEC) enables interrupt-driven, single-cycle data transfers across 8 channels independent of CPU load.
On-chip clock generation uses a programmable PLL (1.5×–5× multiplication), prescaler, or direct XTAL input; power management includes Idle, Sleep, and Power Down modes with oscillator watchdog and programmable watchdog timer. The CAN interface supports Full CAN mode with 15 dedicated message objects and automatic retransmission.

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 | 64 KB mask ROM instead of OTP; identical CAN, ADC, and timer specs | Fixed firmware only - unsuitable for field updates or prototyping iterations | Select when production volume justifies ROM NRE cost and firmware is fully validated |
| C167CS-LM | Enhanced C166 core (100 ns @ 40 MHz), 128 KB ROM, no on-chip OTP, same CAN/ADC peripherals | Higher performance but requires external programming infrastructure; lacks OTP convenience | Choose for throughput-critical applications where 40 MHz execution outweighs OTP flexibility |
Compared with SAK-C164CI-8R25M and C167CS-LM, the C164CI8EMCBFXQMA1 uniquely balances field-programmable OTP, full CAN 2.0B, and deterministic real-time response - making it optimal for low-to-mid volume industrial controllers requiring firmware agility without sacrificing protocol compliance.

FAQ
What is the maximum operating frequency and required supply voltage for C164CI8EMCBFXQMA1?
The C164CI8EMCBFXQMA1 operates at up to 25 MHz with a nominal supply voltage of 5 V ±10%. Its internal PLL supports multiplication factors from 1.5× to 5×, enabling precise clock synthesis from low-frequency crystals. The device is rated for industrial temperature range (−40°C to +85°C) and maintains timing integrity across this range under specified VDD conditions.
Does C164CI8EMCBFXQMA1 support in-system programming of its OTP memory?
No - OTP programming requires dedicated high-voltage (12.5 V) VPP applied to the EA/VPP pin and a specific programming sequence executed via the bootstrap loader or external programmer. In-system programming is not supported; programming must occur before final PCB assembly or in a controlled test environment with appropriate voltage sequencing.
How many CAN message objects does the on-chip CAN controller support, and what protocol version is implemented?
The on-chip CAN controller supports exactly 15 dedicated message objects and implements CAN protocol revision 2.0B active, supporting both standard (11-bit) and extended (29-bit) identifiers. It operates in Full CAN mode with hardware message filtering, automatic retransmission, and error confinement - compliant with ISO 11898-1.
Can the C164CI8EMCBFXQMA1's ADC operate concurrently with PWM generation without CPU intervention?
Yes - the 10-bit ADC can be triggered by CAPCOM6 PWM events (e.g., center-aligned edge), and conversion results can be transferred via the Peripheral Event Controller (PEC) to RAM without CPU involvement. This enables synchronized current sensing in motor control loops with jitter-free sampling aligned to PWM carrier edges.
