Product details
Overview
SPC5673KF0VMM1R from NXP Semiconductors (formerly Freescale) is a dual-core Qorivva 32-bit automotive MCU based on Power Architecture® e200z7d cores, operating up to 150 MHz with 1 MB flash, 256 KB SRAM, and hardware lock-step safety redundancy for ISO 26262 ASIL-D chassis control applications including radar-based ADAS sensor fusion.
For engineers reviewing the SPC5673KF0VMM1R datasheet, SPC5673KF0VMM1R pinout, SPC5673KF0VMM1R application, or SPC5673KF0VMM1R equivalent, key selection criteria include dual-core lock-step operation, 257-pin MAPBGA package, integrated FlexCAN/FlexRay/Ethernet peripherals, ECC-protected memory, and SafeAssure functional safety enablement for automotive chassis systems.
Technical Context
The SPC5673KF0VMM1R implements two e200z7d cores in lock-step or decoupled mode with shared 16 KB I-cache and 16 KB D-cache, both with error detection coding (EDC), and includes redundant CPU core, interrupt controller, crossbar switch, memory protection units, and ECC-protected flash/SRAM controllers. It supports Harvard architecture execution and variable-length encoding (VLE) for code density optimization.
Its safety architecture features sphere-of-replication (SoR) for critical subsystems-CPU, DMA, timers, watchdog, and bus bridges-with lock-step checking units at each SoR output. The device integrates dual crossbar interconnects, MMU with 64 entries, and Nexus Class 3+ debug support for real-time trace and fault injection testing.

FAQ
What is the maximum operating frequency of the SPC5673KF0VMM1R?
The SPC5673KF0VMM1R operates at a maximum core frequency of 150 MHz with ±2% frequency margin, validated across its full AEC-Q100 Grade 1 temperature range (−40°C to +125°C). This frequency is achieved using the on-chip frequency-modulated PLL with external crystal reference, and supports deterministic real-time execution for ASIL-D control tasks. The SPC5673KF0VMM1R does not support the 180 MHz mode available in higher variants like the SPC5675KF0VMM1R.
Does the SPC5673KF0VMM1R support FlexRay communication?
Yes, the SPC5673KF0VMM1R includes one FlexRay module with 64 message buffers, supporting time-triggered communication for high-integrity chassis networks such as brake-by-wire and active suspension systems. The FlexRay controller is integrated into the safety sphere-of-replication and supports built-in CRC, header check, and synchronization gap monitoring. This capability is confirmed in the official MPC567XKUPDTFS specification document.
What safety certifications apply to the SPC5673KF0VMM1R?
The SPC5673KF0VMM1R is developed under NXP's SafeAssure functional safety program and is designed to support ISO 26262 ASIL-D compliance. It includes hardware safety mechanisms such as lock-step dual cores, ECC memory, redundant interrupt controllers, and clock/voltage monitors. While the device itself is not individually certified, NXP provides FMEDA reports, safety manuals, and diagnostic software libraries to enable system-level ASIL-D certification. The SPC5673KF0VMM1R is not rated for IEC 61508 SIL3 out-of-the-box.
Is the SPC5673KF0VMM1R pin-compatible with other MPC567xK variants?
No, the SPC5673KF0VMM1R is not pin-compatible with SPC5674KF0VMM1R or SPC5675KF0VMM1R. All three share the 257-pin MAPBGA package, but the SPC5674K and SPC5675K are only offered in 473-pin packages. The SPC5673KF0VMM1R uses the 257-pin variant exclusively, and its pin mapping-including power domains, peripheral assignments, and debug signals-is unique to this configuration. Board-level reuse requires verification against the specific SPC5673KF0VMM1R pinout diagram.
What development tools are supported for the SPC5673KF0VMM1R?
The SPC5673KF0VMM1R is supported by Freescale CodeWarrior IDE, Green Hills MULTI, and Wind River Diab compilers, along with P&E Micro and Lauterbach debug probes featuring Nexus Class 3+ trace. Runtime software includes AUTOSAR-compliant MCU abstraction layer, Flash/ECC drivers, and software core self-test libraries-all part of the SafeAssure enablement suite. These tools are validated for use with the SPC5673KF0VMM1R and documented in the MPC567XKUPDTFS release notes.
