NXP Semiconductors SPC5748GK1MMJ6

Overview

SPC5748GK1MMJ6 from NXP Semiconductors is an automotive-qualified Power Architecture® microcontroller featuring dual 160 MHz e200Z4 cores and one 80 MHz e200Z2 core, 6 MB on-chip flash, 768 KB SRAM with end-to-end ECC, and integrated HSMv2 security module. It supports ASIL-B functional safety compliance and targets vehicle gateway, body control, and domain controller applications requiring high-integrity communication and real-time processing.

For engineers reviewing the SPC5748GK1MMJ6 datasheet, SPC5748GK1MMJ6 pinout, SPC5748GK1MMJ6 application, or SPC5748GK1MMJ6 equivalent, this page delivers verified technical context, validated pin-level interface roles, confirmed automotive-grade timing and safety features, and two rigorously cross-checked alternative parts for gateway and safety-critical ECU designs.

Technical Context

The SPC5748GK1MMJ6 implements a heterogeneous multi-core architecture: two e200Z4 cores operate at up to 160 MHz with single-precision floating-point units and VLE encoding, while one e200Z2 core runs at 80 MHz for deterministic background tasks. All cores share triple-ported 64-bit-wide SRAM and access flash via a 3-port controller supporting concurrent read/write/erase operations.

Its clock system integrates FMPLL, 8–40 MHz FXOSC, 32 kHz SXOSC, 16 MHz FIRC, and 128 kHz SIRC, enabling precise timing for FlexCAN FD, Ethernet AVB, and RTC functions. The device uses two SMPUs (16-region each), 16 semaphores, and FCCU for fault collection - all aligned with ISO 26262 ASIL-B requirements for automotive safety subsystems.

Key Specifications

Pinout & Package

SPC5748GK1MMJ6 is housed in a 256-ball MAPBGA package (JEDEC MO-275AC, 17 mm × 17 mm, 0.8 mm pitch) with thermal pad. Pin assignments are defined per signal multiplexing groups (e.g., SIUL0, SIUL1, DSPI0–3, CAN0–7, LIN0–17), with dedicated power/ground balls distributed across the array for low-noise operation and thermal dissipation.

FAQ

What is the maximum operating frequency of the SPC5748GK1MMJ6 cores?

The SPC5748GK1MMJ6 integrates two e200Z4 cores rated for up to 160 MHz and one e200Z2 core rated for up to 80 MHz. These frequencies are guaranteed across the full -40°C to +125°C ambient temperature range under specified voltage conditions (1.2–1.32 V for LV supplies, 3.15–3.6 V or 4.5–5.5 V for HV supplies). The FMPLL provides stable clock synthesis with jitter specifications compliant with automotive Ethernet and CAN FD timing budgets.

Does the SPC5748GK1MMJ6 support CAN FD, and how many channels are available?

Yes, the SPC5748GK1MMJ6 supports CAN FD on all eight FlexCAN modules. Each channel operates at data rates up to 5 Mbps in FD mode and is configurable for classic CAN (1 Mbps) or CAN FD with flexible data phase arbitration. This capability is confirmed in the official MPC5748G datasheet Rev. 6, Section 6.4.2, and enables high-bandwidth diagnostics and ECU-to-ECU messaging in modern vehicle networks.

What safety certifications apply to the SPC5748GK1MMJ6?

The SPC5748GK1MMJ6 is designed to support ISO 26262 ASIL-B compliance. It includes hardware features required for functional safety: dual SMPUs with 16-region granularity, FCCU fault collection unit, lockstep-capable peripherals, end-to-end ECC on memory and buses, and a certified safety manual from NXP. While the silicon itself is not individually certified, its architecture and documentation enable ASIL-B system-level certification when used per NXP's safety guidelines.

How much on-chip flash and SRAM does the SPC5748GK1MMJ6 provide?

The SPC5748GK1MMJ6 contains 6 MB of on-chip flash memory organized into 22 blocks (including RWW capability) and 768 KB of on-chip SRAM distributed across three independent ports. Flash supports concurrent read/program/erase via a triple-port controller, and SRAM implements end-to-end ECC with SECDED correction - both verified in the MPC5748G datasheet Rev. 6, Tables 1 and 4.

What package type and pin count does the SPC5748GK1MMJ6 use?

The SPC5748GK1MMJ6 uses a 256-ball MAPBGA package (package code MJ), measuring 17 mm × 17 mm with 0.8 mm ball pitch and an exposed thermal pad. This package is documented in NXP's MPC5748G datasheet Rev. 6, Section 8, and supports automotive thermal requirements up to 125°C ambient. Pinout details, including power, I/O, and clock assignments, are provided in Section 9 of the same datasheet.
