Product details
Overview
C167CRL33MHAKXQLA2 from Infineon Technologies is a 16-bit ROMless microcontroller based on the C167 architecture, featuring a 33 MHz CPU clock, 144-pin MQFP package, and integrated peripherals including CAPCOM6, GPTA, and on-chip RAM. It serves as a real-time control unit in industrial motor drives requiring deterministic interrupt response and high-speed I/O handling.
For engineers reviewing the C167CRL33MHAKXQLA2 datasheet, C167CRL33MHAKXQLA2 pinout, C167CRL33MHAKXQLA2 application, or C167CRL33MHAKXQLA2 equivalent, key selection criteria include CPU frequency headroom, peripheral set alignment with motion control firmware stacks, and MQFP thermal performance under continuous PWM load conditions.
Technical Context
The C167CRL33MHAKXQLA2 implements the C166S V2 core with instruction pipelining and a 3-stage execution pipeline, supporting up to 33 million instructions per second (MIPS). It integrates a 6-channel capture/compare unit (CAPCOM6) for precise PWM generation and edge-triggered input capture.
Its General Purpose Timer Array (GPTA) provides flexible timer resources for multi-axis position control loops, while the on-chip 1.5 KB RAM supports real-time stack and data buffering without external memory access latency.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon C167CS-32L | 32 MHz max clock, 100-pin QFP, no GPTA, reduced CAPCOM6 channel count (4) | Limited to single-axis or lower-bandwidth motion control | Select when cost sensitivity outweighs need for multi-axis coordination or higher PWM resolution |
| STMicroelectronics ST10F269 | 32-bit ST10 core, 40 MHz, 128-pin LQFP, integrated CAN controller, no CAPCOM6 | Better suited for networked distributed control but lacks dedicated motor control peripherals | Prefer when CAN-based system architecture dominates over local PWM precision requirements |
Compared with C167CS-32L and ST10F269, the C167CRL33MHAKXQLA2 offers superior integration of motion-specific peripherals (CAPCOM6 + GPTA) and higher clock headroom for complex control algorithms, making it optimal for standalone, high-fidelity motor control without external co-processors.

FAQ
Is C167CRL33MHAKXQLA2 pin-compatible with other C167 variants?
No. The C167CRL33MHAKXQLA2 uses a 144-pin MQFP package with unique pin assignments for its CAPCOM6 and GPTA modules. Pin compatibility is limited to the C167CR series in the same 144-MQFP variant; migration from 100-pin or 128-pin C167 derivatives requires PCB redesign due to differing I/O mapping and power pin locations.
Does this MCU include an internal oscillator or require external crystal?
The C167CRL33MHAKXQLA2 requires an external crystal or ceramic resonator for main clock generation. It does not include an internal RC oscillator capable of sustaining 33 MHz operation. A 33 MHz crystal connected between X1 and X2 pins is standard, with optional PLL multiplication for higher internal bus speeds in compatible derivatives (not supported in this ROMless version).
What debug interface does C167CRL33MHAKXQLA2 support?
This MCU supports Infineon's OCDS (On-Chip Debug Support) interface via dedicated TDI, TDO, TCK, and TMS pins. It enables full JTAG-based debugging including breakpoint setting, register inspection, and real-time memory access without halting peripheral operation-critical for validating motor control timing behavior during live testing.
Can C167CRL33MHAKXQLA2 execute code from external memory?
Yes. As a ROMless device, it boots from external memory mapped at address 0x000000. It supports external program memory via its multiplexed AD0–AD15 bus and control signals (RD, WR, CS), enabling execution from parallel Flash or SRAM. Boot mode is selected by hardware strapping pins (BS0/BS1), with no internal boot ROM to override external fetch behavior.
