NXP Semiconductors SPC5604BF2MLQ6

Overview

SPC5604BF2MLQ6 from NXP Semiconductors is a 32-bit automotive microcontroller based on the Power Architecture® e200z0h core, operating up to 64 MHz with 512 KB code flash, 64 KB data flash, and 48 KB SRAM - all featuring ECC protection. It integrates six FlexCAN modules, four LINFlex interfaces, three DSPI controllers, and a 10-bit ADC with 36 channels, targeting body control modules and gateway ECUs in 12 V automotive systems.

For engineers reviewing the SPC5604BF2MLQ6 datasheet, SPC5604BF2MLQ6 pinout, SPC5604BF2MLQ6 application, or SPC5604BF2MLQ6 equivalent, key selection criteria include its LQFP-144 package, FMPLL clock generation, Nexus 2+ debug interface, real-time counter with autonomous wakeup, and support for AUTOSAR-compliant timing via STM and PIT modules.

Technical Context

The SPC5604BF2MLQ6 implements the e200z0h CPU core with Variable Length Encoding (VLE) for reduced code footprint and operates at up to 64 MHz using its frequency-modulated PLL (FMPLL). Its crossbar switch enables concurrent access to flash, SRAM, and peripherals by multiple bus masters including eMIOS, FlexCAN, and DSPI.

It features a Memory Protection Unit (MPU) with eight region descriptors and 32-byte granularity, an Interrupt Controller (INTC) supporting 148 vectors, and a Boot Assist Module (BAM) enabling flash programming over CAN or SCI. The device includes dedicated hardware blocks for safety-critical functions: ECSM for error reporting, CTU for ADC-timer synchronization, and WKPU with 18 external wakeup sources.
