Product details
Overview
SPC5604PEF0MLQ6 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, dual 10-bit ADCs (15-channel each), FlexCAN 2.0B interface, and FlexRay v2.1 - designed for electric power steering (EPS) and airbag control systems.
For engineers reviewing the SPC5604PEF0MLQ6 datasheet, SPC5604PEF0MLQ6 pinout, SPC5604PEF0MLQ6 application, or SPC5604PEF0MLQ6 equivalent, key selection criteria include functional safety support (FCU, safety port), ASIL-B-capable peripherals, 144-pin LQFP package, –40°C to 125°C operation, and AUTOSAR-compliant timer modules (STM, PIT).
Technical Context
The SPC5604PEF0MLQ6 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 low-power execution. 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 arbitration.
Functional safety is embedded at silicon level: the Fault Collection Unit (FCU) monitors system-level faults, the safety port repurposes a second FlexCAN channel for up to 7.5 Mbit/s fail-safe communication, and all memory blocks (code flash, data flash, SRAM) include ECC with single-bit correction/double-bit detection - meeting requirements for ISO 26262 ASIL-B applications.

Key Features
| Feature | Design Value |
|---|---|
| Safety Port FlexCAN | Second FlexCAN module configurable as safety-critical communication channel up to 7.5 Mbit/s - enables redundant CAN paths without external hardware |

FAQ
What is the maximum operating frequency of the SPC5604PEF0MLQ6 CPU core?
The SPC5604PEF0MLQ6 features an e200z0h core rated for up to 64 MHz operation. This frequency is achieved using the on-chip FMPLL with a 4–40 MHz external crystal or oscillator input. The core supports Variable Length Encoding (VLE) to maintain performance efficiency at lower clock rates, and its timing is validated across the full –40°C to 125°C temperature range specified for the SPC5604PEF0MLQ6.
Does the SPC5604PEF0MLQ6 support AUTOSAR-compliant software stacks?
Yes, the SPC5604PEF0MLQ6 is widely used with AUTOSAR-compliant toolchains and OS configurations. Its STM (System Timer Module), PIT (Periodic Interrupt Timer), and Nexus L2+ debug interface provide the precise timing sources and trace capabilities required for AUTOSAR OS scheduling and RTE integration. The SPC5604PEF0MLQ6's memory protection, ECC, and FCU also align with AUTOSAR safety extensions for ASIL-B applications.
What is the role of the safety port in the SPC5604PEF0MLQ6?
The safety port in the SPC5604PEF0MLQ6 is a configurable mode of the second FlexCAN module that operates at up to 7.5 Mbit/s with enhanced error handling and message filtering - intended for fail-operational communication paths in ASIL-B systems. Unlike standard FlexCAN, the safety port supports stricter timeout monitoring and dedicated message object allocation, and it can be used independently or alongside the primary FlexCAN interface without requiring PCB changes to the SPC5604PEF0MLQ6 design.
Can the SPC5604PEF0MLQ6 operate with both 3.3 V and 5 V I/O supplies?
Yes, the SPC5604PEF0MLQ6 supports either 3.3 V or 5 V for its I/O and ADC power domains (VDDIO/VDDA). The device includes an on-chip voltage regulator (VREG) that accepts a single input supply and uses an external ballast transistor to generate the required core voltage. Designers must configure the VREG settings and select appropriate external components per the SPC5604PEF0MLQ6 datasheet's power management section to ensure stable operation under both supply options.
How does the Cross Triggering Unit (CTU) enhance ADC performance in the SPC5604PEF0MLQ6?
The CTU in the SPC5604PEF0MLQ6 enables hardware-synchronized triggering of ADC conversions using events from eTimer, PIT, or other peripherals - eliminating software-induced jitter and ensuring deterministic sampling timing. For example, in motor control, the CTU can trigger ADC0 and ADC1 simultaneously upon eTimer overflow, capturing current and voltage samples within one system clock cycle. This capability is essential for field-oriented control (FOC) algorithms implemented on the SPC5604PEF0MLQ6.
