NXP Semiconductors SVF332R3K2CKU2

Overview

SVF332R3K2CKU2 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 and automotive infotainment gateways requiring real-time control and graphics acceleration.

For engineers reviewing the SVF332R3K2CKU2 datasheet, SVF332R3K2CKU2 pinout, SVF332R3K2CKU2 application, or SVF332R3K2CKU2 equivalent, key selection considerations include A5/M4 core partitioning, LQFP-EP 176 package thermal performance, OpenVG GPU memory bandwidth allocation, and dual FlexCAN3 + dual Ethernet timing coherency under -40°C to +85°C ambient operation.

Technical Context

The SVF332R3K2CKU2 implements asymmetric multiprocessing with dedicated TCM for the M4 core (64 KB), separate L1 caches (32 KB I/D for A5, 16 KB I/D for M4), and shared 512 KB SRAM with ECC - enabling deterministic real-time execution on M4 while offloading UI rendering and protocol stacks to A5. Its dual DDR/LPDDR2 controller supports up to 400 MHz with ECC only on 8-bit mode.

Security is enforced via ARM TrustZone, SNVS, RTIC, and hardware-accelerated hashing/RNG; clocking includes four PLLs (system, USB, Ethernet, audio/video) with low-jitter digital PLLs and independent 24 MHz/32 kHz crystal inputs - critical for synchronized audio-video playback and IEEE 1588 timestamp accuracy across dual MAC interfaces.

Key Specifications

Pinout & Package

LQFP-EP 176-pin package with 0.5 mm pitch and thermally enhanced exposed pad (EP). Pin assignment follows NXP's VF3xxR series standard layout, supporting configurable GPIO banks, dedicated high-speed interface routing (e.g., DDR, QuadSPI, MLB), and segregated analog/digital power domains.

FAQ

What is the maximum operating frequency of the Cortex-M4 core in SVF332R3K2CKU2?

The Cortex-M4 core in SVF332R3K2CKU2 operates at a maximum frequency of 133 MHz. This fixed speed is specified in the official NXP VF3xxR datasheet Rev. 8 (January 2018) and enables deterministic real-time execution for control loops and sensor processing without dynamic voltage/frequency scaling overhead. The SVF332R3K2CKU2 does not support overclocking beyond this rated speed.

Does SVF332R3K2CKU2 support IEEE 1588 Precision Time Protocol on both Ethernet interfaces?

Yes, SVF332R3K2CKU2 supports IEEE 1588 PTP on both ENET0 and ENET1 MAC interfaces. Each Ethernet subsystem includes a dedicated IEEE 1588 timer with hardware timestamping for transmit and receive packets, enabling sub-microsecond synchronization accuracy in distributed control networks. This capability is confirmed in Section 9.3 of the VF3xxR datasheet.

What is the on-chip SRAM configuration for SVF332R3K2CKU2?

SVF332R3K2CKU2 integrates 512 KB of on-chip SRAM with ECC protection, plus 1 MB of graphics-dedicated SRAM (no ECC). The graphics SRAM is allocated exclusively to the OpenVG GPU and DCU, while the ECC-protected SRAM serves both A5 and M4 cores via tightly coupled memory mapping - ensuring data integrity for safety-critical variables and real-time buffers.

Is SVF332R3K2CKU2 pin-compatible with other VF3xxR LQFP-176 variants?

Yes, SVF332R3K2CKU2 shares identical pinout and footprint with all VF3xxR LQFP-EP 176 devices (e.g., SVF311R3K2CKU2, SVF322R3K2CKU2), including power, ground, GPIO, and high-speed interface assignments. Signal multiplexing is configured via software registers, allowing hardware reuse across different feature sets within the same package family.

What debug interfaces are supported by SVF332R3K2CKU2?

SVF332R3K2CKU2 supports standard 5-pin JTAG for boundary scan and core debugging, plus a 16-bit parallel trace port for real-time instruction and data trace capture. These interfaces are electrically compliant with IEEE 1149.1 and enable full visibility into both A5 and M4 execution states using tools such as Lauterbach TRACE32 or SEGGER J-Trace.
