Product details
Overview
SPC5674KFF0MMS2R from NXP Semiconductors (formerly Freescale) is a dual-core Qorivva 32-bit automotive MCU based on Power Architecture e200z7 cores, operating up to 180 MHz with 1.5 MB flash, 384 KB SRAM, and hardware lock-step redundancy for ISO 26262 ASIL-D safety-critical chassis control and ADAS radar imaging systems.
For engineers reviewing the SPC5674KFF0MMS2R datasheet, SPC5674KFF0MMS2R pinout, SPC5674KFF0MMS2R application, or SPC5674KFF0MMS2R equivalent, this page delivers verified core architecture, memory mapping, safety features, peripheral integration, and real-world deployment context for functional safety validation and system-level timing-critical design.
Technical Context
The SPC5674KFF0MMS2R implements two e200z7d cores in lock-step or decoupled parallel mode, each with 16 KB I-cache and 16 KB D-cache, MMU (64 entries), SPE2, VLE, and Harvard architecture. It supports nominal platform frequencies of 0–90 MHz in 1:1/1:2/1:3 modes with ±2% frequency modulation tolerance.
Hardware safety mechanisms include crossbar-based SoR (Sphere of Replication) covering CPU, DMA, interrupt controller, flash/RAM controllers, and watchdogs, with lock-step checking units at all SoR outputs and dual ECC-protected memory subsystems (flash, SRAM, EEPROM).

FAQ
What is the maximum operating frequency of the SPC5674KFF0MMS2R?
The SPC5674KFF0MMS2R operates at a maximum core frequency of 180 MHz with ±2% frequency modulation tolerance. This rating applies to both e200z7d cores in lock-step or decoupled mode and is validated across the full industrial temperature range. The nominal platform frequency is 90 MHz in 1:1 mode, supporting deterministic timing for safety-critical ADAS tasks. SPC5674KFF0MMS2R achieves this performance while maintaining full ECC protection and SoR integrity checks.
Does the SPC5674KFF0MMS2R support ISO 26262 ASIL-D compliance?
Yes, the SPC5674KFF0MMS2R is designed to support ISO 26262 ASIL-D compliance as part of NXP's SafeAssure program. Its hardware safety features-including lock-step dual cores, SoR replication of critical peripherals, ECC on all memory blocks, and hardware fault collection units-reduce software safety case burden. SPC5674KFF0MMS2R documentation, FMEDA reports, and safety manuals are provided to aid system-level certification.
What package type and pin count does the SPC5674KFF0MMS2R use?
The SPC5674KFF0MMS2R uses a 473-pin MAPBGA package (19 mm × 19 mm, 0.8 mm pitch) with exposed thermal pad. This package supports full I/O routing for its 4×FlexCAN, FlexRay, MDDR, PDI, and quad ADC interfaces. Pin definitions follow NXP's MPC567XKUPDTFS Rev 0 specification, and the device is not offered in smaller pin-count variants like the 257-pin version used by lower-memory derivatives.
How much on-chip flash and SRAM does the SPC5674KFF0MMS2R include?
The SPC5674KFF0MMS2R integrates 1.5 MB of on-chip flash memory and 384 KB of SRAM, both with full ECC protection. The flash includes dedicated EEPROM emulation sections (4×16 KB), and the SRAM is partitioned to support lock-step monitoring and safety partitioning. These capacities are fixed for this specific variant and differ from the 1 MB/256 KB (MPC5673K) and 2 MB/512 KB (MPC5675K) configurations.
Which development tools are officially supported for the SPC5674KFF0MMS2R?
NXP officially supports the SPC5674KFF0MMS2R with CodeWarrior Development Studio for Power Architecture, Green Hills MULTI IDE, and Wind River Diab Compiler. Debugging is enabled via Nexus Class 3+ interface using P&E Micro or Lauterbach TRACE32 probes. AUTOSAR-compliant drivers (MCAL), SafeAssure safety libraries, and flash self-test software are included in the SPC5674KFF0MMS2R SDK.
