Product details
Overview
C167SRLMHABXUMA2 from Infineon Technologies is a 16-bit single-chip microcontroller with 2 kB on-chip XRAM, 25 MHz CPU clock, CAN 2.0B interface, and 10-bit 16-channel A/D converter. It integrates dual CAPCOM units, 4-channel PWM, two general-purpose timers, and supports external memory expansion up to 16 Mbytes. Used in industrial motor control systems requiring real-time I/O handling and deterministic communication.
For engineers reviewing the C167SRLMHABXUMA2 datasheet, C167SRLMHABXUMA2 pinout, C167SRLMHABXUMA2 application, or C167SRLMHABXUMA2 equivalent, key selection criteria include CAN message object count (15), A/D conversion time (as low as 7.8 µs), interrupt latency (down to 40 ns), and support for PLL-based clock multiplication (×1.5 to ×5).
Technical Context
The C167SRLMHABXUMA2 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 8 channels, reducing CPU overhead in high-speed I/O applications.
It features an on-chip CAN 2.0B controller with full CAN capability (15 message objects), hardware-supported arbitration and error handling, and integrated oscillator watchdog for clock failure detection. The A/D converter supports programmable sampling time and automatic channel sequencing without CPU intervention.

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 |
|---|---|---|---|
| C167CR-LM | Same core, identical package, but includes 32 KB mask ROM instead of ROMless configuration | Requires pre-programmed firmware; not suitable for bootloader-based field updates | Select when fixed application code is finalized and ROM cost advantage outweighs flexibility |
| C167SR-L33M | Same feature set with 33 MHz max CPU clock (vs. 25 MHz); otherwise pin- and code-compatible | Higher throughput for compute-intensive tasks; requires tighter timing validation on external bus | Select when system demands >20% higher instruction throughput and board layout supports 33 MHz timing margins |
Compared with C167CR-LM and C167SR-L33M, the C167SRLMHABXUMA2 offers optimal balance of deterministic real-time performance, CAN integration, and field-upgradable flexibility-making it preferred for evolving industrial firmware deployments where ROM size and clock headroom are secondary to configurability and proven qualification.

FAQ
Does C167SRLMHABXUMA2 include on-chip flash or ROM memory?
No. The C167SRLMHABXUMA2 is a ROMless variant: it contains 2 kB IRAM and 2 kB XRAM but no on-chip non-volatile program memory. Firmware must be loaded externally via bootstrap loader using UART or parallel port, or executed from external EPROM/Flash via the multiplexed bus interface.
What is the maximum external memory bandwidth supported by the C167SRLMHABXUMA2?
The external bus supports up to 16 Mbytes address space with programmable wait states per chip-select region. At 25 MHz CPU clock, maximum theoretical bandwidth is ~12.5 MB/s for 16-bit demultiplexed accesses with zero wait states, though practical throughput depends on external device timing and bus arbitration overhead.
Can the on-chip CAN module operate in Basic CAN mode only?
No. The CAN module fully supports CAN 2.0B Active specification, including both Basic CAN (11-bit ID) and Full CAN (29-bit ID) modes. All 15 message objects are individually configurable for ID masking, direction (TX/RX), and acceptance filtering-enabling mixed-ID network participation without external protocol translation.
Is the C167SRLMHABXUMA2 qualified for automotive applications?
While widely used in automotive body electronics, this specific part (C167SRLMHABXUMA2) carries industrial temperature grade (–40°C to +85°C) and is not AEC-Q100 qualified. For automotive-grade deployment, Infineon offers pin-compatible derivatives such as SAF-C167CR-LM with extended qualification testing and automotive-specific documentation.
