Product details
Overview
C167CRLMHAFXUMA2 from Infineon Technologies is a 16-bit ROMless microcontroller based on the C167 architecture, featuring a 25 MHz CPU clock, 64 KB on-chip RAM, and a 144-pin MQFP package. It integrates a 10-bit ADC with 16 channels, six capture/compare units, and a high-speed general-purpose timer array for real-time control in industrial motor drives.
For engineers reviewing the C167CRLMHAFXUMA2 datasheet, C167CRLMHAFXUMA2 pinout, C167CRLMHAFXUMA2 application, or C167CRLMHAFXUMA2 equivalent, key selection criteria include its ROMless execution capability via external program memory interface, deterministic interrupt latency under 1.2 µs, and support for synchronous serial communication (SSC) and CAN 2.0B controller.
Technical Context
The C167CRLMHAFXUMA2 implements the C166 v2 core with register-based architecture and instruction set optimized for embedded control. It supports external program memory access via 16-bit address/data multiplexed bus with programmable wait-state generation and burst-mode read capability.
Its peripheral set includes a multi-channel PWM unit with dead-time insertion, a watchdog timer with windowed mode, and an on-chip oscillator circuit supporting crystal or external clock input up to 25 MHz. The device operates over –40°C to +85°C and requires a single 5 V supply.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit ROMless microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| C167CR-LM HAXUMA2 | Same die, but 128-pin LQFP package; lacks P2.0–P2.7 pins required for full A16–A23 addressing | Not suitable for >64 KB external code memory mapping due to reduced address bus width | Select only if external memory footprint ≤64 KB and PCB layout favors LQFP |
| C167CS-LM HAXUMA2 | Includes 256 KB on-chip ROM; removes need for external program memory but increases BOM cost and limits field updates | Preferred for fixed-function, high-volume products where firmware immutability is acceptable | Choose when boot reliability and reduced board area outweigh flexibility and upgradeability needs |
Compared with C167CR-LM HAXUMA2, the C167CRLMHAFXUMA2 supports full 24-bit addressing for larger program images; versus C167CS-LM HAXUMA2, it trades internal ROM for field-programmability and lower initial tooling cost.

FAQ
Does C167CRLMHAFXUMA2 require an external crystal to operate?
Yes - it includes an on-chip oscillator circuit but requires an external 1–25 MHz crystal or clock source connected to X1/X2 pins. No internal RC oscillator is provided, so timing accuracy and stability depend entirely on the external resonator's specification and PCB layout.
Can C167CRLMHAFXUMA2 execute code directly from external Flash memory?
Yes - with EA pin held low, the device fetches instructions from external memory mapped at 0x000000–0xFFFFFF. The parallel bus supports 16-bit data width, programmable wait states, and burst reads, enabling efficient execution from standard 5V NOR Flash devices such as Intel StrataFlash or Spansion GL series.
What is the maximum ADC sampling rate achievable with hardware synchronization?
When triggered by GPTA compare events, the ADC achieves a sustained sampling rate of 100 kSPS across all 16 channels. Each conversion completes in ≤10 µs, and the hardware trigger eliminates software overhead, ensuring jitter below ±20 ns between sample instances.
Is the CAN controller compatible with ISO 11898-1 physical layer?
No - the integrated CAN 2.0B controller handles protocol layer only (data link and application). An external CAN transceiver (e.g., Infineon TLE6250 or TI SN65HVD230) is required to implement ISO 11898-1 differential signaling, bus termination, and fault protection.
