Product details
Overview
SPC5604PEF1MLQ6R from NXP Semiconductors (formerly Freescale) is an automotive-grade 32-bit Power Architecture MCU with e200z0h core, 512 KB on-chip code flash (ECC), 40 KB SRAM (ECC), and 64 MHz max CPU frequency. It integrates FlexCAN 2.0B (32 message objects), FlexRay V2.1 (dual/single channel, up to 10 Mbit/s), and dual 10-bit ADCs (15-channel each, <1 µs conversion). Designed for electric power steering (EPS) and airbag control systems.
For engineers reviewing the SPC5604PEF1MLQ6R datasheet, SPC5604PEF1MLQ6R pinout, SPC5604PEF1MLQ6R application, or SPC5604PEF1MLQ6R equivalent, key selection criteria include functional safety support (FCU, safety port), ASIL-B-capable peripherals, dual CAN/FlexRay coexistence, and 144-pin LQFP package compatibility with automotive thermal requirements (–40 to 125 °C).
Technical Context
The SPC5604PEF1MLQ6R implements a single-issue, in-order e200z0h CPU core compliant with Power Architecture embedded category and supports Variable Length Encoding (VLE) for compact code footprint. Its crossbar switch (XBAR) enables concurrent instruction fetch from flash and data transfers via eDMA across four master ports-including e200z0 instruction/data, eDMA, and FlexRay-while managing arbitration between three slave ports (flash, SRAM, peripheral bridge).
Real-time determinism is enforced by a 147-source interrupt controller (INTC) with 16 priority levels and hardware vectored interrupts, paired with fail-safe mechanisms including programmable software watchdog timer (SWT), non-maskable interrupt (NMI), and fault collection unit (FCU). Clocking relies on dual sources: 4–40 MHz external crystal oscillator and 16 MHz internal RC oscillator, both feeding a software-configurable FMPLL capable of 64 MHz system clock output with triangle-wave frequency modulation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPC5606B | Same e200z0h core, 64 MHz, but includes integrated voltage regulator (VREG) and enhanced ADC resolution (12-bit); lacks FlexRay module | Better suited for cost-sensitive EPS variants where FlexRay is unnecessary and integrated power management simplifies BOM | Select MPC5606B when FlexRay is not required and board space/power design favors integrated regulation over external ballast transistor |
| SPC564A70L7 | Successor Qorivva family part with e200z4 core, 120 MHz, 1 MB flash, dual FlexRay, and ASIL-D ready safety features; pinout incompatible | Targets next-gen ADAS-integrated chassis controllers requiring higher compute, larger memory, and certified safety architecture | Choose SPC564A70L7 for new designs targeting ASIL-D compliance and future scalability; SPC5604PEF1MLQ6R remains optimal for established ASIL-B EPS/ACU platforms |
Compared with MPC5606B, SPC5604PEF1MLQ6R provides FlexRay and safety port capabilities essential for chassis domain networking, while SPC564A70L7 offers higher performance and safety certification at the cost of migration effort and increased BOM cost - making SPC5604PEF1MLQ6R the balanced choice for production-ready ASIL-B automotive control.

Does the SPC5604PEF1MLQ6R support AUTOSAR-compliant software stacks?
Yes, the SPC5604PEF1MLQ6R supports AUTOSAR-compliant software stacks through its system timer module (STM), 147-source interrupt controller (INTC), and Nexus L2+ debug interface. NXP provides official AUTOSAR Basic Software (BSW) modules and MCAL drivers validated for SPC5604PEF1MLQ6R, enabling seamless integration with commercial and open-source AUTOSAR runtimes for EPS and ACU deployments.
How does the safety port functionality work on the SPC5604PEF1MLQ6R?
The safety port on the SPC5604PEF1MLQ6R is implemented as a dedicated FlexCAN channel with hardware-enforced isolation, supporting bit rates up to 7.5 Mbit/s and 32 message objects. It operates independently from the primary FlexCAN interface and includes dedicated error counters, FIFOs, and CRC checking - enabling redundant communication paths for ISO 26262 ASIL-B diagnostics without software overhead or shared resource contention.
What are the flash memory endurance and retention specifications for the SPC5604PEF1MLQ6R?
The SPC5604PEF1MLQ6R specifies 100,000 program/erase cycles for code flash memory and 100,000 cycles for data flash (EEPROM emulation mode), with data retention guaranteed for 20 years at 125 °C junction temperature.
