Product details
Overview
C167CRLMHAKXQLA1 from Infineon Technologies is a 16-bit single-chip microcontroller with 128 KB on-chip mask ROM, 2 KB internal RAM, and 2 KB XRAM, operating at 25 MHz CPU clock (40 ns instruction cycle), featuring integrated CAN 2.0B interface, 16-channel 10-bit ADC, dual CAPCOM units, and PWM module - deployed in industrial motor control and embedded automation systems.
For engineers reviewing the C167CRLMHAKXQLA1 datasheet, C167CRLMHAKXQLA1 pinout, C167CRLMHAKXQLA1 application, or C167CRLMHAKXQLA1 equivalent, key selection criteria include CAN message object count (15), ADC conversion time (as low as 7.8 µs), PLL clock multiplication factors (1.5× to 5×), and support for external bus arbitration with five chip-select signals.
Technical Context
The C167CRLMHAKXQLA1 implements a 4-stage pipelined 16-bit CPU with register-based architecture, single-cycle context switching, and 16 Mbyte linear address space. It integrates a dedicated Peripheral Event Controller (PEC) enabling interrupt-driven, single-cycle data transfers across eight channels.
Its on-chip peripherals include two synchronous/asynchronous serial channels, dual 16-channel capture/compare units with programmable dead-time insertion, and a watchdog timer with oscillator watchdog supervision - all synchronized to the same clock domain derived from the configurable PLL.

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 |
|---|---|---|---|
| C167CS-16R33M | Same core and peripherals but rated for 33 MHz operation; 128 KB ROM, no BGA option | Higher CPU throughput (303 ns division vs. 606 ns) - beneficial for complex PID cascades or multi-axis interpolation | Select when deterministic sub-300 ns math operations are required and board layout supports higher-speed signal integrity |
| XE167FN-128F100L | Successor generation with 100 MHz CPU, 128 KB Flash, enhanced CAN FD support, and integrated debug interface | Replaces mask-ROM with field-programmable Flash; adds JTAG and trace - suited for prototyping and iterative firmware development | Choose for new designs requiring lifecycle flexibility, toolchain continuity, and future CAN FD upgrade path |
Compared with C167CRLMHAKXQLA1, the C167CS-16R33M delivers higher deterministic compute bandwidth for math-intensive control loops, while the XE167FN-100L offers Flash-based reprogrammability and modern debug infrastructure - making the original ideal for cost-sensitive, high-volume, fixed-function deployments where ROM reliability and long-term supply stability are critical.

FAQ
Is C167CRLMHAKXQLA1 pin-compatible with other C167CR derivatives in MQFP-144 package?
Yes - all C167CR variants in P-MQFP-144-8 package share identical pinout, including C167CRLMHAKXQLA1, C167CR-4RM, and C167CR-16R33M. Power, ground, oscillator, reset, and peripheral signal assignments are functionally and physically consistent across the derivative family per datasheet Section 2.2.
Does C167CRLMHAKXQLA1 support in-system programming (ISP)?
No - it contains mask-programmed ROM and lacks on-chip Flash or EEPROM. Firmware updates require replacement of the device. However, its integrated bootstrap loader enables serial reprogramming of external memory devices via UART, supporting field-upgradable peripheral firmware stored externally.
What is the maximum ambient temperature rating for C167CRLMHAKXQLA1?
The device is specified for industrial temperature range: –40 °C to +85 °C. This is confirmed in Table 1 of the datasheet under "SAK-C167CR-LM" derivative, which matches the ordering suffix "LM" in C167CRLMHAKXQLA1 - indicating industrial-grade qualification and screening.
Can the on-chip CAN module operate without an external transceiver?
No - C167CRLMHAKXQLA1 provides only the CAN protocol controller (CANRX/CANTX logic-level pins). An external physical-layer transceiver (e.g., Infineon TJA1040 or TI SN65HVD230) is mandatory to drive the differential CAN_H/CAN_L bus lines and provide fault protection.
