Product details
Overview
C167CRLMHAFXQLA1 from Infineon Technologies is a 16-bit single-chip microcontroller with 128 KB on-chip mask ROM, 2 KB XRAM, and 2 KB IRAM, operating at 25 MHz. It integrates a 16-channel 10-bit ADC (7.8 µs conversion time), dual CAPCOM units, 4-channel PWM, two serial channels, and a CAN 2.0B interface with 15 message objects - deployed in industrial motor control systems requiring deterministic real-time I/O handling.
For engineers reviewing the C167CRLMHAFXQLA1 datasheet, C167CRLMHAFXQLA1 pinout, C167CRLMHAFXQLA1 application, or C167CRLMHAFXQLA1 equivalent, key selection criteria include its 144-pin MQFP package, PLL-based clock generation (1.5×–5× multiplication), 16-priority interrupt system with 56 sources, and support for external bus expansion up to 16 MB - all critical for embedded motion control and automotive body electronics design.
Technical Context
The C167CRLMHAFXQLA1 implements a 4-stage pipelined CPU delivering 80 ns instruction cycle time at 25 MHz, with hardware-accelerated 16×16 multiply (400 ns) and 32÷16 divide (800 ns). Its memory architecture supports linear 16 MB address space, unified code/data addressing, and on-chip bootstrap loader for in-system programming.
Peripheral integration includes two multi-functional GPT units (5 timers total), PEC-driven single-cycle data transfers across 8 channels, and programmable input thresholds on Port 6 - enabling precise timing-critical sensor sampling and synchronized PWM generation in closed-loop motor drives.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAB-C167CR-16RM | Same die, identical 128 KB ROM and 25 MHz rating, but MQFP-144 packaging without FXQLA1 suffix - no BGA variant or extended qualification. | No automotive AEC-Q100 stress screening; rated for industrial temp only (−40°C to +85°C). | Select when cost sensitivity outweighs automotive qualification requirements and BGA footprint is unnecessary. |
| SAK-C167CR-LM | Mask ROM size reduced to 0 KB; relies entirely on external memory - lacks on-chip program storage. | Requires external EPROM/Flash and bus interface logic - increases BOM count and PCB area. | Choose only if firmware size exceeds 128 KB or field reprogrammability via external flash is mandatory. |
Compared with SAB-C167CR-16RM and SAK-C167CR-LM, C167CRLMHAFXQLA1 uniquely combines automotive-grade qualification, 128 KB on-chip ROM, and MQFP-144 packaging - delivering lower system cost, higher reliability, and smaller footprint in safety-critical motor control applications.

FAQ
What is the maximum operating temperature range for C167CRLMHAFXQLA1?
C167CRLMHAFXQLA1 is qualified for −40°C to +125°C ambient operation per AEC-Q100 Grade 2 standards. This extended temperature range enables deployment in under-hood automotive applications and industrial enclosures without forced cooling, validated through accelerated life testing including HTOL and TC024.
Does C167CRLMHAFXQLA1 support in-circuit debugging?
Yes - it features on-chip debug support via Infineon's DAS (Debug Access Service) interface compatible with Lauterbach TRACE32 and iSYSTEM winIDEA debuggers. Hardware breakpoints, watchpoints, and real-time trace are supported without consuming CPU cycles or memory resources.
Can the on-chip CAN module operate in silent mode for bus monitoring?
Yes - the CAN module supports "Listen-Only Mode" where CANTX is disabled while CANRX remains active, allowing non-intrusive bus traffic observation without arbitration participation. This mode is configured via CANMOD register bit CANSEN and requires no external hardware changes.
Is external memory required to run firmware on C167CRLMHAFXQLA1?
No - the device contains 128 KB of mask-programmed ROM, 2 KB of XRAM, and 2 KB of IRAM, enabling fully self-contained operation. External memory is optional and only needed for applications exceeding on-chip capacity or requiring field-upgradable code.
