What the SPC5603BF2CLL4 is and where it fits
The NXP SPC5603BF2CLL4 is a 32-bit single-core microcontroller from the Qorivva MPC56xx family, built around the e200z0h Power Architecture core. It runs at 48 MHz and integrates 384 KB of Flash program memory, 64 KB of EEPROM, and 28 KB of RAM. The part is aimed at automotive body electronics, gateway modules, and industrial control applications that need CAN and LIN connectivity in a -40°C to 85°C environment.
Memory and peripheral mix for body-domain control
With 384 KB of Flash and 64 KB of EEPROM, this MCU can hold a substantial body-control firmware stack plus calibration data that survives power loss. The 28 KB RAM is enough for CAN message buffers and local state variables without external SRAM. On-chip DMA offloads the core during periodic sensor reads or CAN frame handling. The 79 I/O lines, along with CANbus, LINbus, I²C, SPI, and SCI interfaces, cover the typical peripheral set for door modules, seat controllers, and HVAC panels.
Supply range and temperature grade
The 3 V to 5.5 V supply range covers automotive and industrial rails. The -40°C to 85°C operating range suits passenger cabin and most industrial enclosures.
Package and lifecycle
The SPC5603BF2CLL4 comes in a 100-pin LQFP (14x14 mm) — a common, inspectable, and reworkable package.
