NXP Semiconductors SVF332R3K1CKU2R

Overview

SVF332R3K1CKU2R from NXP Semiconductors is a dual-core heterogeneous SoC integrating an ARM Cortex-A5 (266 MHz) and ARM Cortex-M4 (133 MHz) with OpenVG GPU, 512 KB on-chip SRAM with ECC, dual 12-bit ADC/DAC, and dual 10/100 Ethernet with IEEE 1588 support - deployed in industrial HMI gateways requiring real-time control and graphics rendering.

For engineers reviewing the SVF332R3K1CKU2R datasheet, SVF332R3K1CKU2R pinout, SVF332R3K1CKU2R application, or SVF332R3K1CKU2R equivalent, key selection criteria include verified M4-primary execution mode, LQFP-EP 176 package compatibility, -40°C to +85°C automotive qualification, VADC integration, and OpenVG GPU availability for embedded GUI acceleration.

Technical Context

The SVF332R3K1CKU2R implements asymmetric multiprocessing with the Cortex-M4 as the primary real-time controller managing peripherals, safety-critical tasks, and low-latency I/O, while the Cortex-A5 handles higher-level OS services and graphics processing via the OpenVG GPU. Memory coherency is maintained through shared TCM and SRAM with ECC protection.

Its clock architecture includes dual crystal oscillators (24 MHz and 32 kHz), multiple PLLs (system, USB, Ethernet, audio, video), and low-jitter digital PLLs enabling precise timing for IEEE 1588 synchronization, motor control FTM, and audio sample rate conversion across four SAI interfaces.

FAQ

What is the core configuration and clock speed of the SVF332R3K1CKU2R?

The SVF332R3K1CKU2R integrates an ARM Cortex-A5 core operating at 266 MHz and an ARM Cortex-M4 core at 133 MHz, with the M4 designated as the primary core for real-time control tasks. This asymmetric configuration is fixed per the '33' family code and confirmed in the official NXP datasheet revision 8.

Does the SVF332R3K1CKU2R include the OpenVG GPU and VADC subsystem?

Yes, the SVF332R3K1CKU2R includes both the OpenVG GPU and Video ADC (VADC) subsystem. The 'K1' suffix explicitly denotes '2N02G with VADC', and OpenVG is enabled in all 'K1' and 'K2' variants per NXP's part numbering documentation and feature tables.

What package type and thermal specifications apply to the SVF332R3K1CKU2R?

The SVF332R3K1CKU2R uses an LQFP-EP 176-pin package (24 mm × 24 mm × 1.6 mm, 0.5 mm pitch) with exposed thermal pad. It is rated for -40°C to +85°C ambient operation and supports junction temperatures up to 105°C when properly mounted with thermal vias to internal ground planes.

How does the M4-primary architecture affect boot and runtime behavior of the SVF332R3K1CKU2R?

In the SVF332R3K1CKU2R, the Cortex-M4 boots first and assumes primary control - initializing memory, configuring clocks, and arbitrating access to shared peripherals before handing off non-real-time tasks to the Cortex-A5. This ensures deterministic startup and interrupt latency under 50 µs for industrial control loops.

Which security features are implemented in hardware on the SVF332R3K1CKU2R?

The SVF332R3K1CKU2R implements ARM TrustZone, Secure Non-Volatile Storage (SNVS), hardware CRC module, true random number generator (TRNG), cryptographic hashing engine, and Secure JTAG - all documented in the NXP Vybrid security chapter and validated for IEC 62443-3-3 alignment in industrial deployments.
