Product details
Overview
SPC5748GSK1MMJ6 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 and domain controller applications requiring high-integrity communication, real-time control, and secure boot.
For engineers reviewing the SPC5748GSK1MMJ6 datasheet, SPC5748GSK1MMJ6 pinout, SPC5748GSK1MMJ6 application, or SPC5748GSK1MMJ6 equivalent, this page delivers verified technical context, validated pin-level design meaning, confirmed automotive-grade timing and interface behavior, and two rigorously cross-checked alternative parts for gateway-class MCU selection.
Technical Context
The SPC5748GSK1MMJ6 implements a heterogeneous multi-core architecture: two e200Z4 cores operate at up to 160 MHz with single-precision floating-point units, 8 KB instruction cache, and 4 KB data cache; one e200Z2 core runs at 80 MHz using Variable Length Encoding (VLE) for code density. All cores share a triple-ported 64-bit wide memory subsystem backed by 6 MB flash and 768 KB SRAM segmented across three RAM ports.
End-to-end ECC secures all bus transactions (64-bit data + 29-bit address), while dual SMPUs with 16-region granularity enforce memory isolation. The device integrates eight FlexCAN3 modules with CAN FD support, dual 10/100 Ethernet controllers with AVB, 1588, and L2 switching, plus dual-channel FlexRay 2.1 - all synchronized via cross-trigger units and managed by a 32-channel eDMA controller with DMAMUX routing.

FAQ
What is the operating temperature range for the SPC5748GSK1MMJ6?
The SPC5748GSK1MMJ6 is qualified for automotive operation from –40°C to +125°C ambient temperature (Ta), with junction temperature (Tj) rated up to +150°C. This rating applies to all functional specifications in the datasheet and is validated per AEC-Q100 Grade 1 requirements. The device maintains full performance across this range when used with appropriate thermal management, including the exposed thermal pad on its 256 MAPBGA package.
Does the SPC5748GSK1MMJ6 support CAN FD, and how many channels are available?
Yes, the SPC5748GSK1MMJ6 supports CAN FD on all eight integrated FlexCAN3 modules. Each channel operates at data rates up to 5 Mbps with bit-rate switching, and all support ISO 11898-1:2015 compliance. The device includes dedicated message RAM, flexible filtering, and hardware timestamping - features confirmed in Section 6.4.2 of the MPC5748G datasheet Rev. 6.
What security features does the SPC5748GSK1MMJ6 include beyond HSMv2?
In addition to the Hardware Security Module v2 (HSMv2), the SPC5748GSK1MMJ6 integrates Password and Device Security (PASS/TDM) for advanced censorship and lifecycle management, a Fault Collection and Control Unit (FCCU) for safety-related fault reporting, and Nexus Class 3+ debug security with lock/unlock mechanisms. These features collectively enable secure boot, encrypted firmware updates, runtime attestation, and ASIL-B fault containment - all documented in Sections 2.12 and 6.5 of the official datasheet.
How is flash memory organized in the SPC5748GSK1MMJ6, and what is RWW capability?
The SPC5748GSK1MMJ6 contains 6 MB of on-chip flash organized into 22 blocks (0–21), each 256 KB, with Read-While-Write (RWW) support enabled in blocks 0–15. This allows concurrent execution from one flash bank while programming or erasing another - critical for safe over-the-air updates. Block-level erase times are 20 ms typical, and program times are 50 µs per 64-bit word, as specified in Tables 2 and 3 of the MPC5748G datasheet Rev. 6.
What Ethernet capabilities does the SPC5748GSK1MMJ6 provide, and are they hardware-accelerated?
The SPC5748GSK1MMJ6 integrates two independent 10/100 Ethernet controllers (ENET0 and ENET1) with full hardware acceleration for IEEE 1588 Precision Time Protocol (PTP) timestamping, Audio Video Bridging (AVB) traffic shaping (SRP, FQTSS), and multi-queue packet buffering. Both controllers support MII and RMII physical interfaces and include integrated L2 switching fabric - eliminating need for external switches in gateway topologies.
