Product details
Overview
C164CI8EMCBKXQMA1 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, 8-channel 10-bit ADC (7.8 µs conversion time), and a 25 MHz CPU clock supporting 12.5 MIPS. It integrates CAPCOM6 for flexible PWM generation, three general-purpose timers, two serial channels, and real-time clock functionality - deployed in industrial motor control and automotive body electronics.
For engineers reviewing the C164CI8EMCBKXQMA1 datasheet, C164CI8EMCBKXQMA1 pinout, C164CI8EMCBKXQMA1 application, or C164CI8EMCBKXQMA1 equivalent, key selection criteria include OTP-based firmware immutability, CAN 2.0B compliance with full message object support, 80-pin MQFP package constraints, and compatibility with Infineon's C166 toolchain including macro-assembler and HLL debuggers.
Technical Context
The C164CI8EMCBKXQMA1 implements a 4-stage pipelined 16-bit CPU with register-based architecture, single-cycle context switching, and 16 MByte linear address space. Its peripheral event controller (PEC) enables 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. The CAN interface complies with ISO 11898 Rev. 2.0B and supports both Full CAN and Basic CAN modes via 15 dedicated message objects with priority arbitration.
Key Specifications

Pinout & Package
80-pin MQFP package (0.65 mm pitch), thermally optimized for industrial ambient temperatures up to +85 °C. Pin assignments follow Infineon's standardized C164CI pinout layout with multiplexed address/data bus (P0L/P0H), dedicated CAN signal routing on Port 4/Port 8, and dual power/ground pairs for noise suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| P0L.0–P0L.7 / P0H.0–P0H.7 | Multiplexed AD0–AD15 bus | Lower/upper byte of 16-bit address/data bus - used for external memory access with ALE strobe synchronization |
| P4.5–P4.6 / P8.0–P8.3 | CAN TX/RX and message object I/O | Configurable as CANL/CANH physical layer signals or CC16IO–CC19IO for CAPCOM6 PWM output |
| RSTIN / RSTOUT | Reset input/output | Asynchronous reset assertion (RSTIN); open-drain reset status output (RSTOUT) for system-level reset chaining |
| VAREF / VAGND | Analog reference inputs | Provide precision 5 V reference and analog ground return for 10-bit ADC - must be decoupled locally |
Key Features
| Feature | Design Value |
|---|---|
| OTP Program Memory | 64 KB one-time programmable ROM - eliminates need for external boot EEPROM and prevents runtime firmware tampering |
| Full CAN 2.0B Controller | 15 hardware message objects with individual ID masking, transmit/receive FIFOs, and automatic retransmission on error |
| Peripheral Event Controller (PEC) | 8-channel DMA-like transfer engine - moves data between peripherals and memory without CPU intervention |
| Flexible Clock System | On-chip PLL with selectable multiplication factors (1.5×–5×) and bypass mode - enables precise timing across variable load conditions |
| Power Management Modes | Idle, Sleep, and Power Down states with configurable wake-up sources - reduces active current to <100 µA in Sleep mode |
Applications
| Industrial Motor Control | Automotive Body Electronics |
|---|---|
Use Scenario: Closed-loop speed and position control of 3-phase BLDC motors in HVAC blowers and pump drives. IC Role / Device Role / Timing Role: Primary motion controller executing FOC algorithms, sampling current/voltage via 10-bit ADC, generating 6-channel PWM via CAPCOM6, and communicating fault status over CAN. Use Value: Integrated CAN 2.0B and deterministic 25 MHz execution enable synchronized multi-node motor coordination without external protocol ICs. | Use Scenario: Central body controller managing door locks, window lifts, mirror adjustment, and interior lighting in mid-tier vehicles. IC Role / Device Role / Timing Role: System-on-chip host managing LIN/CAN gateway functions, analog sensor interfacing (potentiometers, temp sensors), and high-side switch drivers. Use Value: 59 GPIOs with selectable hysteresis and 8-channel ADC allow direct connection to diverse automotive sensors and actuators - reducing BOM count. |
| Energy Metering Interface | Programmable Logic Controller (PLC) I/O Module |
Use Scenario: Tamper-resistant electricity meter front-end capturing voltage/current waveforms and computing kWh using on-chip math units. IC Role / Device Role / Timing Role: Real-time waveform acquisition node with 10-bit ADC oversampling, RTC-stamped event logging, and secure OTP-stored calibration constants. Use Value: OTP memory ensures calibration data integrity; watchdog and oscillator watchdog prevent meter drift due to clock failure. | Use Scenario: DIN-rail mounted digital I/O expansion module for industrial PLCs requiring isolated inputs and relay-driven outputs. IC Role / Device Role / Timing Role: Local intelligence unit polling opto-isolated inputs, debouncing signals, driving solid-state relays, and reporting status via CAN bus. Use Value: Three independent timers and PEC enable precise input sampling intervals and jitter-free output pulse widths - critical for safety-rated I/O cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller with integrated CAN applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-C164CI-8R25M | 64 KB mask ROM instead of OTP; identical CAN, ADC, timer, and pinout specs | Suitable only for high-volume production where firmware is finalized pre-mask; no field updates possible | Select when firmware is immutable and cost-per-unit optimization outweighs programming flexibility |
| SAK-C164CL-8R25M | Reduced-function CAPCOM6 (no PWM output capability); otherwise identical memory, CAN, and ADC | Cannot generate complex PWM waveforms - unsuitable for motor control but adequate for simple timing and capture tasks | Select only if CAPCOM6 PWM features are unused and lower cost is prioritized |
Compared with SAK-C164CI-8R25M and SAK-C164CL-8R25M, C164CI8EMCBKXQMA1 uniquely combines OTP programmability with full CAPCOM6 PWM and CAN 2.0B - making it the sole option among these three for prototyping, low-volume production, and applications requiring both motor control and field firmware updates.

FAQ
Is C164CI8EMCBKXQMA1 pin-compatible with other C164CI derivatives?
Yes - all C164CI variants, including SAK-C164CI-8R25M and SAK-C164CL-8R25M, share the identical 80-pin MQFP package and pin mapping. Signal functions may differ on shared pins (e.g., CAPCOM6 vs. GPIO), but mechanical and PCB footprint compatibility is guaranteed across the derivative family.
Does this microcontroller support in-system programming (ISP)?
No - C164CI8EMCBKXQMA1 uses OTP (One-Time Programmable) memory, which is programmed during final wafer test and cannot be reprogrammed after soldering. Firmware updates require replacement of the MCU; no bootloader-based ISP or JTAG flash reprogramming capability exists.
What is the maximum operating temperature range for this part?
C164CI8EMCBKXQMA1 is rated for industrial temperature operation from –40 °C to +85 °C. This range is validated per Infineon's qualification standards and applies to all electrical specifications in the datasheet - no derating required within this envelope.
Can the on-chip CAN controller interface directly with a standard CAN transceiver?
Yes - the C164CI8EMCBKXQMA1's CAN module outputs differential logic-level signals compliant with ISO 11898 physical layer requirements. It requires an external CAN transceiver (e.g., Infineon TLE6250 or TI SN65HVD230) to drive the CAN bus, but all protocol handling (arbitration, error framing, message filtering) is performed internally.
