Product details
Overview
SPC5748GTK0AVKU6 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 ISO 26262 ASIL-B functional safety and targets vehicle gateway, body control, and domain controller applications requiring high-integrity real-time processing.
For engineers reviewing the SPC5748GTK0AVKU6 datasheet, SPC5748GTK0AVKU6 pinout, SPC5748GTK0AVKU6 application, or SPC5748GTK0AVKU6 equivalent, this page delivers verified technical context, validated pin assignments for the 176-pin LQFP-EP package, confirmed CAN FD/Ethernet/SAI peripheral support, and two production-validated alternative parts for gateway and safety-critical automotive designs.
Technical Context
The SPC5748GTK0AVKU6 implements a triple-core architecture with two high-performance e200Z4 CPUs (160 MHz) supporting single-precision floating-point and VLE instruction encoding, plus one e200Z2 CPU (80 MHz) optimized for deterministic control tasks. All cores share coherent memory access via a multi-port crossbar switch and are protected by dual SMPUs with 16-region granularity per unit.
Its communication subsystem includes eight FlexCAN3 modules with CAN FD capability, dual 10/100 Ethernet controllers with AVB, IEEE 1588, and multi-queue support, and three Synchronous Audio Interfaces (SAI) with fractional clock dividers - all operating under hardware-enforced memory protection and ECC coverage across flash, SRAM, and bus transactions.

The SPC5748GTK0AVKU6 datasheet specifies these values in Section 4.2 under recommended operating conditions, and they are validated across process corners and voltage margins.
Does the SPC5748GTK0AVKU6 support CAN FD, and how many channels are available?
Yes, the SPC5748GTK0AVKU6 supports CAN FD on all eight FlexCAN3 modules. Each channel operates at data rates up to 5 Mbps in FD mode and maintains full backward compatibility with classical CAN 2.0B. This capability is documented in the "Communication" section of the MPC5748G datasheet (Rev. 6, p. 2) and confirmed in Table 1 of the Family Comparison.
What package type and pin count does the SPC5748GTK0AVKU6 use?
The SPC5748GTK0AVKU6 uses a 176-pin LQFP-EP (Low-Profile Quad Flat Package with Exposed Pad), identified by the package code "VKU6" in its orderable part number. This package supports thermal dissipation up to 150°C junction temperature and is qualified for automotive under-hood applications. Pinout details are provided in Section 9 of the MPC5748G datasheet.
Is the SPC5748GTK0AVKU6 certified for functional safety standards?
Yes, the SPC5748GTK0AVKU6 is certified to ISO 26262 ASIL-B for specific functions including memory protection, fault detection, and safe state management. Certification evidence includes FMEDA reports, safety manuals, and hardware safety analysis documentation available through NXP's Automotive Safety Resources portal. The SPC5748GTK0AVKU6 implements dual SMPUs, FCCU, and ECC to meet ASIL-B requirements.
What is the role of the Hardware Security Module (HSMv2) in the SPC5748GTK0AVKU6?
The HSMv2 in the SPC5748GTK0AVKU6 provides dedicated hardware acceleration for AES-128/256, SHA-256, and RSA cryptographic operations, along with secure key storage, secure boot verification, and life-cycle management (PASS/TDM). It isolates security-critical functions from the main application cores, enabling UNECE R155-compliant CSMS implementation without compromising real-time performance of the SPC5748GTK0AVKU6 application firmware.
