NXP Semiconductors SVF332R3K1CKU2

Overview

SVF332R3K1CKU2 from NXP Semiconductors (formerly Freescale) is a dual-core heterogeneous SoC integrating an ARM Cortex-A5 running at 266 MHz and an ARM Cortex-M4 as the primary real-time controller, with OpenVG GPU acceleration, 1 MB on-chip SRAM (configurable split between graphics and L2 cache), and support for LPDDR2/DDR3, NAND, QuadSPI, and FlexBus memory interfaces. It targets automotive HMI and industrial display control systems requiring deterministic real-time response alongside rich graphics.

For engineers reviewing the SVF332R3K1CKU2 datasheet, SVF332R3K1CKU2 pinout, SVF332R3K1CKU2 application, or SVF332R3K1CKU2 equivalent, key selection considerations include its M4-primary execution mode, OpenVG GPU capability, -40 °C to +85 °C automotive temperature grade, 176-pin LQFP-EP package, and integrated security features including TrustZone, SNVS, and hardware RNG.

Technical Context

The SVF332R3K1CKU2 implements a tightly coupled dual-core architecture where the Cortex-M4 executes real-time tasks-including motor control via FTM timers, sensor acquisition via dual 12-bit SAR ADCs (1 MS/s), and secure boot from Boot ROM-while the Cortex-A5 handles higher-level OS services and graphics rendering via the OpenVG GPU. Memory coherency is managed through shared TCM and configurable SRAM partitioning.

Its system-level timing infrastructure includes dual crystal oscillators (24 MHz and 32 kHz), multiple PLLs (system, USB, Ethernet, audio, video), and IEEE 1588-capable Ethernet MACs. Security is enforced at silicon level via ARM TrustZone, Secure Non-Volatile Storage (SNVS), TrustZone Watchdog, and hardware-accelerated hashing and random number generation.

Key Specifications

Pinout & Package
