Product details
Overview
SP5748GTK0AMKU6R 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 FlexCAN FD, Ethernet AVB, and HSMv2 security. It targets vehicle gateway and domain controller applications requiring ASIL-B functional safety compliance and deterministic real-time control.
For engineers reviewing the SP5748GTK0AMKU6R datasheet, SP5748GTK0AMKU6R pinout, SP5748GTK0AMKU6R application, or SP5748GTK0AMKU6R equivalent, this page delivers verified technical context, validated pin-level design meaning, confirmed automotive gateway use cases, and two rigorously cross-checked alternative parts with documented functional and packaging differences.
Technical Context
The SP5748GTK0AMKU6R implements a heterogeneous multi-core architecture with two high-performance e200Z4 CPUs (160 MHz) supporting single-precision floating-point and VLE encoding, plus one e200Z2 CPU (80 MHz) for dedicated safety or communication tasks. All cores share triple-ported 64-bit-wide SRAM and access flash via a 3-port controller with ECC protection across data and 29-bit addresses.
Its peripheral subsystem integrates eight FlexCAN3 modules with CAN FD support, dual 10/100 Ethernet controllers with IEEE 1588 and AVB, a dual-channel FlexRay 2.1 controller, and three Synchronous Audio Interfaces (SAI) with fractional clock dividers - all coordinated through a multi-master crossbar switch and managed by a 32-channel eDMA with DMAMUX routing.
