NXP Semiconductors SPC5668EK0MMGR

Overview

SPC5668EK0MMGR from NXP Semiconductors is a 32-bit Power Architecture automotive microcontroller featuring an e200z650 CPU core (116 MHz), 2 MB on-chip flash, 128 KB ECC SRAM, 32-channel eDMA, 5 FlexCAN modules, 32-channel eMIOS200 timers, and a Cross-Triggering Unit (CTU) for synchronized ADC triggering - deployed in engine control units and chassis domain controllers.

For engineers reviewing the SPC5668EK0MMGR datasheet, SPC5668EK0MMGR pinout, SPC5668EK0MMGR application, or SPC5668EK0MMGR equivalent, key selection criteria include its 256-ball MAPBGA package, –40 °C to 105 °C operating range, CTU-enabled ADC timing coordination, 5 FlexCAN interfaces with 64 mailboxes, and absence of Ethernet/FlexRay/MLB peripherals compared to MPC5668G variants.

Technical Context

The SPC5668EK0MMGR implements a dual-core architecture: the e200z650 main core (116 MHz, 32 KB unified cache, VLE/FP/SPE support) and e200z0 I/O processor (58 MHz). It integrates a Frequency-Modulated PLL (FMPLL) with 4–40 MHz crystal input and dedicated 16 MHz/128 kHz RC oscillators.

Its analog subsystem includes a 10-bit ADC with 32 external + 64 internal channels, directly triggered by the Cross-Triggering Unit (CTU) using eMIOS200 timers or internal events - enabling deterministic sensor sampling in real-time powertrain control loops without CPU intervention.

Key Specifications

Pinout & Package

SPC5668EK0MMGR uses a 256-ball MAPBGA package (17 mm × 17 mm, 0.8 mm pitch), Pb-free, tape-and-reel delivery. Pin assignments are defined in NXP document MPC5668X Rev. 7, Section 3.2.

Equivalent & Alternatives

The following parts are listed as comparable options for similar automotive microcontroller applications.

Compared with MPC5668GF1AVMJ4, SPC5668EK0MMGR trades Ethernet/FlexRay for CTU and MPU - making it suitable for ASIL-B powertrain control rather than networked gateways. Against SPC560P50L5CEFAR, it delivers higher performance, larger memory, and certified safety features essential for modern engine management.

FAQ

What is the maximum operating frequency of the SPC5668EK0MMGR?

The SPC5668EK0MMGR operates at a maximum static frequency of 116 MHz on its e200z650 core, enabled by its frequency-modulated phase-locked loop (FMPLL) with 4–40 MHz crystal input. This speed is guaranteed across the full –40 °C to +105 °C operating range and supports deterministic real-time execution for automotive control tasks. The e200z0 I/O processor runs at up to 58 MHz.

Does the SPC5668EK0MMGR include hardware support for functional safety standards like ISO 26262?

Yes, the SPC5668EK0MMGR includes multiple hardware features supporting ISO 26262 ASIL-B compliance: ECC protection on both flash and SRAM, a 16-entry Memory Protection Unit (MPU) for memory partitioning, built-in FMPLL monitoring, and Nexus Class 3 debug for runtime verification. These capabilities reduce the need for external safety mechanisms when implementing safety-critical engine or chassis control functions using SPC5668EK0MMGR.

How many CAN interfaces does the SPC5668EK0MMGR support, and what protocol versions are implemented?

The SPC5668EK0MMGR supports five independent FlexCAN modules, each compliant with CAN protocol specification Version 2.0B Active. Each module provides 64 configurable mailboxes (transmit or receive), supporting bit rates up to 1 Mbps. Unlike MPC5668G variants, SPC5668EK0MMGR excludes Ethernet, FlexRay, and MLB interfaces - focusing its peripheral set on CAN-centric automotive control applications.

What is the role of the Cross-Triggering Unit (CTU) in the SPC5668EK0MMGR?

The Cross-Triggering Unit (CTU) in the SPC5668EK0MMGR enables hardware-synchronized triggering of ADC conversions using events from eMIOS200 timers, other peripherals, or internal signals - eliminating software-induced latency. This allows precise, repeatable sampling aligned to PWM edges or mechanical events, which is essential for field-oriented motor control and cylinder-specific engine sensing. The CTU is exclusive to MPC5668E variants like SPC5668EK0MMGR.

What package type and pin count does the SPC5668EK0MMGR use?

The SPC5668EK0MMGR uses a 256-ball MAPBGA package (17 mm × 17 mm, 0.8 mm pitch), Pb-free, supplied in tape-and-reel format (denoted by the 'R' suffix in the part number). This package supports full pin functionality including all 5 FlexCAN interfaces, 32 eMIOS channels, 4 DSPI modules, and the CTU - distinguishing it from the 208-ball variant used in lower-feature MPC5668E derivatives.
