NXP Semiconductors SPC5604PGF0MLL6

Overview

SPC5604PGF0MLL6 from NXP Semiconductors (formerly Freescale) is a 32-bit automotive microcontroller based on the Power Architecture e200z0h core, operating up to 64 MHz with VLE instruction set. It integrates 512 KB code flash with ECC, 40 KB SRAM with ECC, and dual 10-bit ADCs (15-channel each, <1 µs conversion). Designed for electric power steering (EPS) and airbag control systems, it delivers functional safety support via Fault Collection Unit (FCU), programmable watchdog, and Nexus L2+ debug interface.

For engineers reviewing the SPC5604PGF0MLL6 datasheet, SPC5604PGF0MLL6 pinout, SPC5604PGF0MLL6 application, or SPC5604PGF0MLL6 equivalent, key selection considerations include its FlexCAN 2.0B interface with safety port capability (7.5 Mbit/s), FlexRay v2.1 support (10 Mbit/s), dual eTimer units (6×16-bit cascaded channels), and 144-pin LQFP package with –40°C to 125°C operating range.

Technical Context

The SPC5604PGF0MLL6 implements a single-issue, in-order e200z0h CPU core compliant with Power Architecture embedded category, featuring Variable Length Encoding (VLE) for compact code footprint and Harvard architecture with 32-bit GPRs. Its crossbar switch (XBAR) enables concurrent access between four masters (core instruction/data, eDMA, FlexRay) and three slaves (flash, SRAM, peripheral bridge), supporting deterministic real-time scheduling via 147-interrupt-source INTC with 16 priority levels.

Timing subsystems include FMPLL with software-controlled frequency modulation (±0.25–4% deviation), dual 10-bit ADCs synchronized via Cross Triggering Unit (CTU), and FlexPWM with 8 complementary outputs, dead-time control, and ADC synchronization signals - all validated for ASIL-B–capable chassis applications per ISO 26262 requirements.

FAQ

What is the maximum operating frequency of the SPC5604PGF0MLL6 CPU core?

The SPC5604PGF0MLL6 features an e200z0h core rated for operation up to 64 MHz. This maximum frequency is achieved using the FMPLL with a 4–40 MHz crystal input and appropriate multiplication/division settings. The core maintains full functionality-including VLE instruction execution, ECC-protected memory access, and Nexus L2+ debug-at this speed, as verified in Freescale's Rev. 8 datasheet Section 3.17 AC timing characteristics.

Does the SPC5604PGF0MLL6 support AUTOSAR-compliant software stacks?

Yes, the SPC5604PGF0MLL6 supports AUTOSAR-compliant software stacks through its System Timer Module (STM), eDMA controller, and MCAL drivers validated by NXP. Its 147-interrupt INTC with 16 priority levels and hardware priority ceiling protocol enable deterministic task scheduling required by AUTOSAR OS, while CTU-synchronized ADC and FlexPWM facilitate time-triggered sensor actuation per AUTOSAR specifications.

What safety certifications apply to the SPC5604PGF0MLL6?

The SPC5604PGF0MLL6 is AEC-Q100 Grade 1 qualified (–40°C to 125°C) and designed to support ASIL-B system-level compliance per ISO 26262. Key enablers include integrated Fault Collection Unit (FCU), ECC on all on-chip memories, programmable watchdog timer, non-maskable interrupt, and Nexus L2+ interface for runtime verification - all documented in the MPC5604P datasheet Rev. 8 Sections 1.5.15 and 1.5.29.

Can the SPC5604PGF0MLL6 operate with both 3.3 V and 5 V I/O supplies?

Yes, the SPC5604PGF0MLL6 supports both 3.3 V and 5 V digital I/O supply (VDD_IO/VSS_IO) and analog supply (VDDA/VSSA), as specified in Section 3.4 of the Rev. 8 datasheet. Designers must maintain separate power domains and proper decoupling; mixing voltages on the same supply rail is prohibited. The internal voltage regulator supports single-supply operation with external ballast transistor.

Is the SPC5604PGF0MLL6 pin-compatible with other MPC5604P variants?

Yes, the SPC5604PGF0MLL6 shares the same 144-pin LQFP mechanical footprint and pinout with other MPC5604P family members including SPC5604PEF0MLL6 and SPC5604PFF0MLL6, as confirmed in Section 2.1 "Package pinouts" of the MPC5604P datasheet Rev. 8. Functional differences (e.g., FlexRay presence, flash size) do not affect pin assignment or electrical compatibility.
