Product details
Overview
C164SL8RMCAKXQMA1 from Infineon Technologies is a 16-bit CISC microcontroller with on-chip 512 KB ROM, 32 KB RAM, and integrated CAN 2.0B controller. It operates at up to 40 MHz, supports industrial temperature range (−40°C to +125°C), and features a 5 V supply voltage. It is used in automotive body control modules for centralized door/window/lock management.
For engineers reviewing the C164SL8RMCAKXQMA1 datasheet, C164SL8RMCAKXQMA1 pinout, C164SL8RMCAKXQMA1 application, or C164SL8RMCAKXQMA1 equivalent, key selection factors include its CAN interface compliance, ROM/RAM allocation, extended temperature rating, and legacy C166-family instruction set compatibility.
Technical Context
The C164SL8RMCAKXQMA1 implements the C166 v2 core architecture with 16-bit data bus and 24-bit address bus, enabling direct access to up to 16 MB memory space. It integrates a 16-channel general-purpose timer unit, 8-channel ADC with 10-bit resolution, and hardware multiplier for real-time arithmetic.
Its on-chip peripheral set includes a synchronous serial interface (SSI), UART with LIN support, and two capture/compare units for PWM generation. The device uses a single 5 V supply and includes brown-out detection and watchdog timer for automotive-grade reliability.
Key Specifications

Pinout & Package
Package: PG-LQFP-144-17 (144-pin Low-Profile Quad Flat Package, 20 × 20 mm, 0.5 mm pitch).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Power supply and ground | Dual 5 V supply pins with dedicated analog/digital ground separation |
| P0.0–P0.15 | Port 0 bidirectional I/O | 16-bit multiplexed address/data bus during external memory access |
| P2.0–P2.7 | Port 2 general-purpose I/O | Configurable as input/output with pull-up enable; used for CAN TX/RX when enabled |
| CANRX, CANTX | CAN physical layer interface | Differential signal pair routed to external transceiver (e.g., TLE6250) |
| AD0–AD7 | ADC input channels | Analog inputs mapped to Port 2 pins P2.0–P2.7; shared function |
Key Features
| Feature | Design Value |
|---|---|
| On-chip CAN 2.0B controller | Enables direct integration into vehicle body networks without external protocol IC |
| Hardware multiplier unit | Executes 16×16 signed multiply in one cycle - critical for motor control loops |
| 16-channel programmable timer unit | Supports input capture, output compare, and PWM generation with dead-time insertion |
| Brown-out detection (BOD) | Triggers reset if VDD drops below 4.5 V - prevents erratic operation in automotive power dips |
| Watchdog timer with window mode | Ensures software liveness; window violation causes immediate reset - required for ASIL-B systems |
Applications
| Automotive Body Control Module | Central Door Lock System |
|---|---|
Use Scenario: Centralized control of power windows, mirrors, locks, and interior lighting across all vehicle doors. IC Role / Device Role / Timing Role: Main system controller executing CAN-based command arbitration and local actuator sequencing. Use Value: Integrates CAN, ADC, and PWM peripherals in one die - reduces BOM count and PCB area vs. multi-chip solutions. | Use Scenario: Synchronized locking/unlocking of all doors via key fob or interior switch with anti-theft timeout logic. IC Role / Device Role / Timing Role: Real-time state machine managing solenoid drivers, tamper detection, and secure CAN message filtering.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C167CR-LM | Same C166 v2 core, but 1 MB ROM, 64 KB RAM, and enhanced CAN FIFO; no LIN support | Targeted at higher-complexity gateways requiring larger firmware and deeper message buffering | Select when >512 KB code space or >15 concurrent CAN messages are required |
| SAK-C164CS-32L | Legacy C164 variant with 32 KB ROM, 2 KB RAM, and no on-chip CAN - requires external CAN controller | Suitable for cost-sensitive entry-level modules where CAN traffic is minimal or offloaded | Choose only if firmware size <32 KB and external CAN IC is acceptable for BOM flexibility |
Compared with C164SL8RMCAKXQMA1, the C167CR-LM offers greater memory and CAN depth for gateway roles, while the SAK-C164CS-32L trades integration for lower cost and simpler layout - neither matches its balance of CAN integration, memory, and temperature rating for mid-tier body controllers.

FAQ
What is the maximum operating frequency of the C164SL8RMCAKXQMA1?
The C164SL8RMCAKXQMA1 runs at a maximum CPU clock frequency of 40 MHz, achieved using an external crystal or oscillator connected to the XTAL1/XTAL2 pins. Its instruction throughput is 25 MIPS at this speed, with most instructions executing in one or two cycles due to the C166 v2 pipeline architecture.
Does the C164SL8RMCAKXQMA1 support LIN communication?
Yes - the device supports LIN 2.0 via its UART peripheral, which can be configured for LIN master or slave operation using the built-in LIN break detection and synchronization capabilities. No external LIN transceiver is required beyond the standard physical layer driver.
Is there on-chip debug support for this microcontroller?
The C164SL8RMCAKXQMA1 includes an on-chip debug interface compatible with Infineon's DAS (Debug Access Service) protocol. It supports full JTAG-based debugging including breakpoints, watchpoints, and real-time register/memory inspection through the TDI/TDO/TCK/TMS pins.
What packaging and moisture sensitivity level (MSL) does this part have?
C164SL8RMCAKXQMA1 is supplied in PG-LQFP-144-17 package with MSL 3 rating per JEDEC J-STD-020. The "A1" suffix in the OPN confirms standard dry-pack shipping with humidity indicator card and desiccant in sealed moisture barrier bag.
