Product details
Overview
SPC5745BK1VMH2R from NXP Semiconductors is a dual-core automotive microcontroller featuring a 160 MHz Power Architecture® e200z4 CPU and an 80 MHz e200z2 CPU, 2 MB on-chip flash memory, 256 KB SRAM with end-to-end ECC, and integrated FlexCAN with FD support. It targets engine control units (ECUs), transmission control modules, and battery management systems requiring ASIL-B functional safety compliance.
For engineers reviewing the SPC5745BK1VMH2R datasheet, SPC5745BK1VMH2R pinout, SPC5745BK1VMH2R application, or SPC5745BK1VMH2R equivalent, key selection criteria include dual-core deterministic timing, 2 MB flash partitioning for RWW operation, 10-bit + 12-bit ADC concurrency, LINFlexD and FlexCAN3 FD channel count, and 256-pin MAPBGA package thermal performance in under-hood environments.
Technical Context
The SPC5745BK1VMH2R implements a tightly coupled dual-CPU architecture where the e200z4 core handles high-intensity real-time tasks (e.g., fuel injection timing) and the e200z2 manages background diagnostics and communication stacks. Both cores share a crossbar switch enabling concurrent access to 2 MB flash, 256 KB SRAM, and peripherals including eight FlexCAN3 FD controllers.
Its safety architecture includes System Memory Protection Unit (SMPU) with 16 region descriptors, Hardware Security Module (HSMv2), Fault Collection and Control Unit (FCCU), and ISO 26262 ASIL-B-certifiable subsystems - all validated for automotive powertrain applications operating at -40°C to +125°C ambient temperature.
