FFF CompatibilityShares an identical physical 144-pin MQFP package and near-identical pinout assignments. However, Pin 84 serves as OWE (Oscillator Watchdog Enable) on the Infineon part vs RPD on the ST part, requiring a minor schematics check.Both parts utilize the 144-pin MQFP/PQFP package with a 28mm x 28mm body size and 0.65mm lead pitch.Matches the 25 MHz maximum speed, ROMless memory configuration, 4KB RAM, 10-bit ADC, and CAN bus interface of the original part.
AI Summary

ST10R167-Q3 by STMicroelectronics: ST10 ST10 Microcontroller IC 16-Bit 25MHz ROMless 144-PQFP (28x28).

The SAK-C167CR-LM series from Infineon is the direct architectural equivalent of the ST10R167, sharing the same C166 instruction set and near-identical pinout mapping. It represents the closest second-source alternative for legacy compatibility.

  • Architectural sibling sharing the C166 CPU core instructions
  • Matching 144-pin MQFP/PQFP physical package footprint (28x28mm)
  • Identical operating supply voltage range of 4.5V to 5.5V
  • Pin 84 function differs slightly (OWE on Infineon vs RPD on STMicroelectronics)

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
