Tri-core architecture and clock domains
The SPC5747GBK1VMJ6 is a 32-bit Tri-Core microcontroller from the MPC57xx series, built around one e200z2 core clocked at 80 MHz and two e200z4 cores at 160 MHz. This asymmetric multiprocessing arrangement lets the slower core handle safety-monitoring and real-time housekeeping while the faster pair run the application logic and communications stack.
Memory budget and program storage
On-chip program memory is 4 MB of flash (4M x 8), paired with 768 KB of SRAM. The flash holds the firmware image and calibration data; the RAM budget must accommodate the AUTOSAR or safety stack, communication buffers, and the application heap. With 178 I/O lines, the device can drive parallel memory buses or a wide sensor array without external GPIO expanders.
Connectivity and analog front-end
The peripheral set includes CANbus, Ethernet, USB OTG, I²C, LINbus, SAI, and SPI — covering both automotive in-vehicle networks and industrial fieldbus interfaces. The analog subsystem provides 80 channels of 10-bit ADC and 64 channels of 12-bit ADC, enough to read multiple sensor inputs without external multiplexing.
