Overview
MPC561 and MPC562 are 32-bit microcontrollers from the Motorola/Freescale MPC5xx family. NXP's reference manual describes a PowerPC-ISA-compatible RCPU, 32 KiB calibration RAM, timer and analogue subsystems and three TouCAN modules. They are individual MCU types, not interchangeable names for the complete ECU.
Features compared
| Device | On-chip program flash | Instruction code compression | Example evidence |
|---|---|---|---|
| MPC561 | None | Not supported | BitSoftware lists Ford Bosch ME9.0 with MPC561 and external flash. |
| MPC562 | None | Supported | AutoTuner identifies an MPC562 Bosch EDC16C34 application. |
For comparison, NXP lists 512 KiB on-chip flash on MPC563 and MPC564, with compression supported by MPC564. External flash is a separate chip and its presence and contents depend on the ECU. MAGICMOTORSPORT lists Ford and Volvo Bosch ME9 with MPC561/562 and an M58BW016DB external flash example; verify the device fitted to the board in hand.
Working with the ECU
NXP lists BDM and Nexus debug support on the MPC562. A supported workshop tool may provide access through its own BDM/JTAG procedure, but the processor name does not supply a board pinout or establish the correct probe, orientation, supply or memory coverage. Match all of those to the exact ECU and tool instructions, record the hardware and software IDs, and preserve original reads of each supported memory region.
