120 MHz Cortex-M3 with Ethernet and CAN — drive-selection memo
The 120 MHz core speed and dedicated motor-control PWM peripheral (with dead-time generation and fault inputs) make this a natural fit for a three-phase induction or BLDC drive controller running field-oriented control loops. The on-chip 12-bit ADC bank — eight channels — samples current-sense and position feedback without an external converter.
Memory and peripheral allocation
256 KB of Flash and 80 KB of SRAM sit in the mid-range tier for a Cortex-M3 — sufficient for an Ethernet/IP or Modbus TCP stack with a modest application layer, but not sized for a full embedded Linux or heavy GUI framebuffer. The 4 KB of on-chip EEPROM holds calibration constants and failsafe boot parameters without requiring an external serial EEPROM. The external bus interface (EBI/EMI) can map additional SRAM or Flash in the 208-pin package variant.
Lifecycle and sourcing reality
This part carries an Active product status — no last-time-buy notice, no obsolescence risk for new BOM introductions. It remains a standard catalog item through NXP's distribution network. We source and quote it to order against an RFQ; availability and current pricing are confirmed at quote time.
