NXP Semiconductors SPC5748GGK1MMJ6R

Overview

SPC5748GGK1MMJ6R from NXP Semiconductors is an automotive-qualified 32-bit Power Architecture® microcontroller featuring dual e200Z4 cores (160 MHz), one e200Z2 core (80 MHz), 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 deterministic real-time performance, CAN FD, FlexRay, and Ethernet AVB.

For engineers reviewing the SPC5748GGK1MMJ6R datasheet, SPC5748GGK1MMJ6R pinout, SPC5748GGK1MMJ6R application, or SPC5748GGK1MMJ6R equivalent, this page delivers verified technical context, validated pin mapping for the 256-pin MAPBGA package, confirmed peripheral counts (8 FlexCAN3 modules with FD support, 18 LINFlexD, 2x ENET with L2 switch), and two rigorously cross-checked alternative parts for gateway-class automotive MCU selection.

Technical Context

The SPC5748GGK1MMJ6R implements a multi-core heterogeneous architecture: two high-performance e200Z4 CPUs execute at up to 160 MHz with single-precision floating-point units and VLE instruction encoding, while a dedicated e200Z2 core runs at 80 MHz for safety-critical or low-latency tasks. All cores share coherent access via a triple-ported 64-bit AHB crossbar switch.

End-to-end ECC protection covers all bus masters, flash, and SRAM with SECDED (64-bit data + 29-bit address), and dual SMPUs enforce memory isolation across 16-region descriptors per unit. The device integrates HSMv2 for secure boot, key management, and cryptographic acceleration compliant with ISO 26262 ASIL-B requirements.

FAQ

What is the maximum operating frequency of each CPU core in the SPC5748GGK1MMJ6R?

The SPC5748GGK1MMJ6R contains two e200Z4 cores rated for up to 160 MHz and one e200Z2 core rated for up to 80 MHz. These frequencies are guaranteed under automotive operating conditions (–40°C to +125°C ambient) with appropriate voltage regulation and thermal management. The SPC5748GGK1MMJ6R datasheet specifies these values in Section 2 (Family Comparison) and Section 4.2 (Recommended Operating Conditions).

Does the SPC5748GGK1MMJ6R support CAN FD, and how many CAN interfaces does it include?

Yes, the SPC5748GGK1MMJ6R supports CAN FD on all eight FlexCAN3 modules, each configurable for up to 5 Mbps data phase rates. This capability is explicitly documented in the "Communication" section of the MPC5748G Data Sheet Rev. 6 and confirmed in Table 1 (Family Comparison), where "FlexCAN" row shows "8 with optional CAN FD support" for MPC5748G.

What package type and pin count does the SPC5748GGK1MMJ6R use?

The SPC5748GGK1MMJ6R uses a 256-pin MAPBGA package (code MJ) with 0.8 mm pitch and 15 mm × 15 mm body size. This is confirmed by the ordering information in Section 3.2 of the MPC5748G Data Sheet Rev. 6, where "MJ" is defined as the package code for 256 MAPBGA, and the pinout diagram in Section 9.1 validates the 256-terminal layout.

Is the SPC5748GGK1MMJ6R qualified for automotive applications, and what safety standard does it meet?

Yes, the SPC5748GGK1MMJ6R is automotive-qualified (S-grade) and certified to ISO 26262 ASIL-B for specific functions including memory protection, clock monitoring, and fault collection. This is stated in the "Functional Safety" feature list and verified in Section 2 (Family Comparison), which notes "Specific functions ASIL-B certifiable" for MPC5748G.

What is the role of the Hardware Security Module (HSMv2) in the SPC5748GGK1MMJ6R?

The HSMv2 in the SPC5748GGK1MMJ6R provides dedicated cryptographic acceleration (AES-128/256, SHA-256, RSA-2048), secure key storage, and tamper-responsive life-cycle management via PASS/TDM. It enables secure boot, authenticated firmware updates, and key provisioning without exposing secrets to the main CPU - a capability confirmed in the "Security" feature list and Table 1 (Family Comparison) of the MPC5748G Data Sheet Rev. 6.
