Product details
Overview
SPC5673KFF0VMM1R from NXP Semiconductors (formerly Freescale) is a Qorivva 32-bit dual-core automotive MCU based on Power Architecture e200z7d cores, operating up to 150 MHz with 1 MB flash, 256 KB SRAM, and hardware lock-step redundancy for ISO 26262 ASIL-D safety-critical chassis control applications including radar-based ADAS sensor fusion.
For engineers reviewing the SPC5673KFF0VMM1R datasheet, SPC5673KFF0VMM1R pinout, SPC5673KFF0VMM1R application, or SPC5673KFF0VMM1R equivalent, key selection criteria include dual-core lock-step operation, 1 MB ECC flash, 256 KB ECC SRAM, quad 12-bit ADC, four FlexCAN interfaces, and MAPBGA-257 packaging with functional safety support per SafeAssure program.
Technical Context
The SPC5673KFF0VMM1R implements two e200z7d cores in lock-step or decoupled parallel mode, each with 16 KB I-cache and 16 KB D-cache with error detection, MMU with 64 entries, and VLE/PowerPC instruction set compatibility. It integrates dual crossbar switches, memory protection units, and hardware monitoring for CPU, DMA, interrupt controller, and memory subsystems.
Safety architecture includes sphere-of-replication (SoR) for critical components-CPU cores, DMA, crossbar, flash/RAM controllers-with lock-step checking units at all SoR outputs. Clocking uses dual FM-PLLs, 16 MHz IRCOSC, and external crystal support from 4–40 MHz.

The SPC5673KFF0VMM1R includes safety manuals, FMEDA reports, and diagnostic software libraries to accelerate functional safety certification.
Does the SPC5673KFF0VMM1R support AUTOSAR-compliant software stacks?
Yes, the SPC5673KFF0VMM1R is supported by NXP's AUTOSAR Basic Software (BSW) stack, including MCU Abstraction Layer, OS, and CAN/LIN drivers. The SPC5673KFF0VMM1R's dual-core lock-step mode and memory protection units meet AUTOSAR requirements for safety partitions and memory isolation in ASIL-D configurations.
What is the maximum operating frequency of the SPC5673KFF0VMM1R?
The SPC5673KFF0VMM1R operates at up to 150 MHz with ±2% frequency margin, delivering a nominal platform frequency of 75 MHz in 1:1 clock mode. This frequency is validated across the full automotive temperature range (−40°C to 125°C) and supports deterministic real-time execution for chassis control tasks.
How many CAN interfaces does the SPC5673KFF0VMM1R integrate?
The SPC5673KFF0VMM1R integrates four independent FlexCAN modules, each with 32 message buffers and full ISO 11898-1/2 compliance. These interfaces support concurrent communication with radar, camera, gateway, and actuator ECUs without software arbitration, making the SPC5673KFF0VMM1R ideal for distributed ADAS architectures.
Is the SPC5673KFF0VMM1R pin-compatible with other MPC567xK family members?
No, the SPC5673KFF0VMM1R uses a 257-pin MAPBGA package and is not pin-compatible with the 473-pin variants (e.g., SPC5674K/SPC5675K). Pin count, ball layout, and power delivery requirements differ significantly; migration requires PCB redesign and signal integrity revalidation.
