Product details
Overview
SVF331R3K1CKU2R from NXP Semiconductors is a dual-core heterogeneous SoC integrating an ARM Cortex-A5 (266 MHz) and ARM Cortex-M4 (133 MHz) on a single die, with 512 KB on-chip SRAM (ECC), dual 12-bit SAR ADCs (1 MS/s), and dual 12-bit DACs - designed for real-time industrial HMI and motor control edge nodes requiring deterministic M4 execution alongside A5-based Linux-capable application processing.
For engineers reviewing the SVF331R3K1CKU2R datasheet, SVF331R3K1CKU2R pinout, SVF331R3K1CKU2R application, or SVF331R3K1CKU2R equivalent, key selection considerations include its LQFP-EP 176-pin package, -40 °C to +85 °C automotive qualification (S-grade), M4-primary core configuration, VADC integration, and absence of OpenVG GPU - distinguishing it from K2-variant parts.
Technical Context
The SVF331R3K1CKU2R implements a tightly coupled dual-core architecture where the Cortex-M4 executes time-critical tasks (e.g., FTM-based motor control, LPTMR-triggered low-power sensing) while the Cortex-A5 handles higher-layer protocol stacks (FlexCAN3, Ethernet IEEE 1588, USB OTG) and OS services. Memory coherency is managed via shared L2 cache resources only on select VF5xxR variants - not enabled in this VF3xxR part.
Its power architecture includes three independent regulators (HPREG, LPREG, ULPREG) supporting dynamic voltage/frequency scaling across run/stop/wait modes, with hardware CRC, TrustZone security, and SNVS-backed secure boot - enabling certified functional safety and secure firmware updates in industrial gateways.
Key Specifications

FAQ
What is the maximum operating frequency of the Cortex-A5 core in the SVF331R3K1CKU2R?
The SVF331R3K1CKU2R features an ARM Cortex-A5 core rated for up to 266 MHz operation. This frequency is guaranteed across the full -40 °C to +85 °C ambient temperature range and 3.0 V to 3.6 V supply voltage, as specified in the VF3xxR datasheet Rev. 8. The SVF331R3K1CKU2R does not support the 400 MHz configuration found in VF5xxR variants.
Does the SVF331R3K1CKU2R include an OpenVG GPU?
No, the SVF331R3K1CKU2R does not include an OpenVG GPU. Its part number suffix "K1" explicitly denotes the "2N02G with VADC" configuration, which omits the GPU block. GPU functionality is only present in "K2" variants (e.g., SVF331R3K2CKU2), as confirmed by the official NXP part numbering guide and datasheet Table 2.3.
What package type and pin count does the SVF331R3K1CKU2R use?
The SVF331R3K1CKU2R uses a thermally enhanced LQFP-EP package with 176 pins, measuring 24 mm × 24 mm × 1.6 mm. The "KU" in the part number identifies this LQFP-EP variant, distinct from the "MK" BGA-364 option used in VF5xxR devices. Pinout diagrams are provided in Section 12.2 of the VF3xxR datasheet Rev. 8.
Is the SVF331R3K1CKU2R qualified for automotive applications?
Yes, the SVF331R3K1CKU2R carries automotive qualification ("S" grade in the part number), meeting AEC-Q100 Grade 3 requirements for ambient temperature (-40 °C to +85 °C) and ESD robustness (HBM ±2000 V). It is intended for body electronics, gateway modules, and infotainment sub-systems where extended temperature operation and reliability are mandatory.
What memory interfaces are supported by the SVF331R3K1CKU2R?
The SVF331R3K1CKU2R supports QuadSPI (with XIP), NAND Flash (8/16-bit with ECC), FlexBus (8/16/32-bit external parallel bus), and DDR controller interfaces - but only for LPDDR2 (up to 400 MHz) and not DDR3. DDR3 support is exclusive to VF5xxR devices, as documented in Section 9.5.4 of the datasheet.
