Product details
Overview
C167SRLMHAKXUMA2 from Infineon Technologies is a 16-bit single-chip microcontroller featuring a 25 MHz CPU clock, 2 KB on-chip XRAM, 2 KB IRAM, and integrated CAN 2.0B interface with 15 message objects. It includes dual 16-channel CAPCOM units, 4-channel PWM, 10-bit 16-channel ADC (7.8 µs conversion), and supports external memory expansion up to 16 Mbytes. Designed for real-time industrial control systems requiring deterministic interrupt response and embedded networking.
For engineers reviewing the C167SRLMHAKXUMA2 datasheet, C167SRLMHAKXUMA2 pinout, C167SRLMHAKXUMA2 application, or C167SRLMHAKXUMA2 equivalent, key selection criteria include its 144-pin MQFP package, 16-priority-level interrupt system (40 ns sample rate), PLL-based clock generation (×1.5–×5), and mask-ROM-free architecture enabling field-programmable bootstrap loading.
Technical Context
The C167SRLMHAKXUMA2 implements a 4-stage pipelined 16-bit CPU with register-based design, single-cycle context switching, and 16 Mbyte linear address space. Its peripheral set centers on deterministic real-time I/O: two CAPCOM units support encoder interfacing and time-stamped event capture, while the 4-channel PWM unit delivers independent duty-cycle and frequency control for motor drive stages.
Integrated CAN 2.0B controller operates at up to 1 Mbps with hardware message filtering across 15 dedicated objects, eliminating host-CPU overhead for protocol handling. The 10-bit ADC features programmable sampling windows and automatic channel sequencing-critical for synchronized sensor acquisition in closed-loop control loops.

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, 25 MHz, identical pinout-but includes 32 KB mask ROM instead of ROMless configuration | Requires pre-programmed firmware image; unsuitable for field-upgradable designs | Select when boot code is fixed and flash programming infrastructure is unavailable |
| C167CR-16RM | Same package and speed, but adds 128 KB on-chip mask ROM and retains 2 KB XRAM | Supports larger embedded applications (e.g., protocol stacks) without external memory | Choose when application size exceeds 8 KB and external memory access latency is unacceptable |
Compared with C167CR-LM and C167CR-16RM, the C167SRLMHAKXUMA2 offers ROMless flexibility for bootloader-driven field updates and reduced NRE cost, trading off on-chip program storage for adaptability in evolving industrial firmware deployments.

FAQ
What is the maximum operating temperature range for C167SRLMHAKXUMA2?
The C167SRLMHAKXUMA2 is rated for industrial temperature operation from –40 °C to +85 °C, validated per Infineon's qualification standards for extended thermal cycling and high-temperature storage. This range supports deployment in motor control enclosures, under-hood automotive modules, and outdoor energy metering housings without derating.
Does C167SRLMHAKXUMA2 support external memory expansion?
Yes-it provides a full 16 Mbyte external address space with programmable bus timing, five chip-select outputs, and configurable multiplexed/demultiplexed 8- or 16-bit data bus modes. External SRAM, Flash, or peripherals can be mapped into distinct address regions with independent wait-state settings per CS signal.
Is the CAN module compatible with ISO 11898-2 physical layer?
No-the C167SRLMHAKXUMA2 integrates only the CAN protocol controller (Rev. 2.0B). An external ISO 11898-2 compliant transceiver (e.g., Infineon TLE6250 or TI SN65HVD230) must be used between CANTX/CANRX pins and the differential bus to meet physical layer requirements.
How is the 10-bit ADC calibrated for precision measurements?
The ADC includes factory-trimmed offset/gain calibration values stored in on-chip SFRs. Users apply these coefficients in software post-conversion; no external calibration hardware is required. Typical INL is ±1 LSB and DNL is ±0.5 LSB across the full 0–VREF range at 25 °C.
