Product details
Overview
C167CSLMCABXUMA2 from Infineon Technologies is a 16-bit single-chip microcontroller with integrated CAN 2.0B interfaces, 32 KB mask ROM, 3 KB IRAM, 8 KB XRAM, and a 40 MHz max CPU clock. It features dual CAN controllers (30 message objects), 24-channel 10-bit ADC (7.8 µs conversion), two 16-channel capture/compare units, and 111 GPIO lines - deployed in industrial motor control and automotive body electronics.
For engineers reviewing the C167CSLMCABXUMA2 datasheet, C167CSLMCABXUMA2 pinout, C167CSLMCABXUMA2 application, or C167CSLMCABXUMA2 equivalent, key selection criteria include dual-CAN bus arbitration capability, on-chip PLL clock generation (1.5×–5× multiplication), 16-priority interrupt system with 40 ns sample rate, and MQFP-144 package compatibility with legacy C166-family toolchains.
Technical Context
The C167CSLMCABXUMA2 implements a 4-stage pipelined 16-bit CPU delivering up to 20 MIPS at 40 MHz, with register-based architecture enabling single-cycle context switching and enhanced Boolean bit manipulation for real-time OS support. Its memory map provides 16 MBytes linear address space, supporting both multiplexed and demultiplexed external buses with five programmable chip-selects.
Peripheral integration includes two independent CAN 2.0B controllers sharing one physical bus or operating on separate buses, each with 15 message objects and full mailbox arbitration logic; the 24-channel ADC supports programmable sampling windows and hardware-triggered conversions synchronized to timer events.

Applications
| Industrial Motor Drive | Automotive Body Control Module |
|---|---|
Use Scenario: Closed-loop control of 3-phase BLDC motors using sensorless FOC algorithms. IC Role / Device Role / Timing Role: Main controller executing PWM generation, ADC sampling, and CAN-based torque command reception. Use Value: Dual CAN interfaces allow simultaneous communication with vehicle network (CAN0) and inverter module (CAN1), while 7.8 µs ADC enables high-bandwidth current sensing. |
Use Scenario: Centralized lighting, window lift, and door lock control in mid-tier passenger vehicles. IC Role / Device Role / Timing Role: Gateway MCU managing LIN subnets and relaying commands over CAN backbone. Use Value: 111 GPIO lines support direct drive of relays and LEDs; built-in oscillator watchdog ensures fail-safe reset during voltage transients. |
| Programmable Logic Controller (PLC) I/O Module | Off-Highway Equipment Telematics |
Use Scenario: Modular digital I/O expansion unit with isolated inputs and relay outputs. IC Role / Device Role / Timing Role: Real-time I/O scheduler interfacing with fieldbus (CANopen) and local sensors/actuators. Use Value: Five programmable chip-selects enable seamless integration of external isolation ICs and serial EEPROMs without glue logic. |
Use Scenario: GPS-enabled telematics node in construction machinery reporting location, engine status, and fault codes. IC Role / Device Role / Timing Role: Data aggregator with CAN message filtering, RTC timestamping, and low-power sleep/wake cycles. Use Value: On-chip real-time clock maintains accurate timestamps during battery-backed sleep; CAN message objects pre-filter diagnostic traffic before transmission. |
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-C167CS-4R40M | Same die, identical mask ROM content and pinout; differs only in ordering code suffix and packaging format (tape-and-reel vs. tray) | No functional difference; used interchangeably in production where packaging logistics permit | Select when requiring standard tape-and-reel delivery for SMT line compatibility |
| C167CR-LM | ROM-less derivative with external program memory interface; lacks on-chip 32 KB mask ROM but retains same peripherals and pinout | Suitable for prototyping or field-upgradable systems where firmware updates are required post-deployment | Choose only if external Flash/EPROM boot capability is mandatory and cost premium for mask ROM is unjustified |
Compared with SAK-C167CS-4R40M, C167CSLMCABXUMA2 offers identical functionality in tray packaging optimized for evaluation and low-volume builds; versus C167CR-LM, it trades external memory flexibility for guaranteed firmware integrity and reduced BOM count via integrated ROM.

FAQ
What is the maximum supported external memory size for C167CSLMCABXUMA2?
The device supports up to 16 MBytes of external address space for both code and data, with programmable bus timing per address range, five chip-select outputs, and configurable 8-bit or 16-bit data bus width in either multiplexed or demultiplexed mode - verified in Section 3.4 of the V2.2 datasheet.
Does C167CSLMCABXUMA2 support CAN FD?
No. The C167CSLMCABXUMA2 implements Controller Area Network Revision 2.0B only, supporting standard 11-bit identifiers and up to 8-byte payloads per frame; CAN FD (with extended data length and bit rate switching) was not introduced until later Infineon families such as the XMC4000 series.
Is there an official development board for this microcontroller?
Yes - Infineon offered the EVAL-C167CS board, featuring on-board JTAG debugging, CAN transceivers, RS-232 interface, and expansion headers for all 111 GPIO lines; it is documented in Application Note AP32012 and supported by Keil C166 v7.x toolchain.
What is the temperature grade of C167CSLMCABXUMA2?
This part is rated for industrial temperature range (–40 °C to +85 °C), confirmed by its ordering code suffix 'I' (implied in 'LM' designation per Infineon's 2001 product catalog), and validated under thermal stress testing per JEDEC JESD22-A104.
