NXP Semiconductors SPC5604BF2MLH6

Overview

SPC5604BF2MLH6 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 for body electronics control in vehicle door modules, seat controllers, and lighting systems.

For engineers reviewing the SPC5604BF2MLH6 datasheet, SPC5604BF2MLH6 pinout, SPC5604BF2MLH6 application, or SPC5604BF2MLH6 equivalent, key selection criteria include its LQFP-144 package, FMPLL clock generation, Nexus 2+ debug interface, real-time counter with 1 ms wakeup resolution, and support for AUTOSAR-compliant timing via STM and PIT modules.

Technical Context

The SPC5604BF2MLH6 implements a single-issue e200z0h CPU with Variable Length Encoding (VLE) for reduced code footprint and operates at up to 64 MHz using an FMPLL with programmable frequency modulation. 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 (including 18 external wakeup sources), and boot assist via CAN or SCI. The device includes dedicated voltage regulation (VREG), low-voltage detection, and hardware-based error correction for all memory blocks.

FAQ

What is the maximum operating frequency of the SPC5604BF2MLH6?

The SPC5604BF2MLH6 operates at a maximum frequency of 64 MHz, achieved via its Frequency-Modulated Phase-Locked Loop (FMPLL). This speed is validated across the full AEC-Q100 Grade 2 temperature range (−40 °C to +105 °C) and supports deterministic real-time execution for automotive body control tasks without exceeding thermal limits.

Does the SPC5604BF2MLH6 support AUTOSAR-compliant timing services?

Yes, the SPC5604BF2MLH6 supports AUTOSAR timing requirements through its System Timer Module (STM) and six Periodic Interrupt Timers (PIT) with 32-bit resolution. These modules provide precise, jitter-free timing events for OS tick generation, watchdog supervision, and time-triggered communication scheduling - all verified in NXP's AUTOSAR MCAL layer.

How many CAN interfaces does the SPC5604BF2MLH6 integrate?

The SPC5604BF2MLH6 integrates six enhanced FlexCAN modules, each supporting configurable message buffers, bit-rate independence, and error confinement. All six are fully functional in the LQFP-144 package and accessible via dedicated pins - enabling direct connection to multiple vehicle sub-networks without external CAN transceivers or protocol converters.

What debug interface does the SPC5604BF2MLH6 provide?

The SPC5604BF2MLH6 provides a Nexus 2+ development interface compliant with IEEE-ISTO 5001-2003 Class Two Plus. This includes real-time trace, hardware breakpoints, register visibility, and memory access during active execution - supported by industry-standard tools including Lauterbach TRACE32 and PLS UDE.

Is the SPC5604BF2MLH6 qualified for automotive use?

Yes, the SPC5604BF2MLH6 is AEC-Q100 qualified to Grade 2 (−40 °C to +105 °C ambient), with built-in ECC for all memory blocks, MPU-enforced memory isolation, and FMPLL-based EMI reduction - meeting ISO 26262 ASIL-B requirements for body electronics control applications.
