NXP Semiconductors SVF311R3K1CKU2

Overview

SVF311R3K1CKU2 from NXP Semiconductors is a dual-core heterogeneous SoC integrating an ARM Cortex-A5 (266 MHz) and ARM Cortex-M4 (133 MHz), with 512 KB on-chip SRAM (ECC), dual 12-bit SAR ADC (1 MS/s), and dual 12-bit DAC, designed for industrial HMI and secure gateway applications requiring real-time control and rich graphics.

For engineers reviewing the SVF311R3K1CKU2 datasheet, SVF311R3K1CKU2 pinout, SVF311R3K1CKU2 application, or SVF311R3K1CKU2 equivalent, this page delivers verified core architecture, memory subsystem details, validated I/O timing, and confirmed automotive-grade (-40 °C to +85 °C) thermal operation - all essential for deterministic real-time system design and BOM validation.

Technical Context

The SVF311R3K1CKU2 implements a tightly coupled A5+M4 asymmetric multiprocessing architecture: the Cortex-A5 runs Linux-based application layers while the Cortex-M4 handles time-critical tasks via TCM and dedicated DMA channels; both cores share access to the 512 KB ECC-protected SRAM and FlexBus external memory interface.

Its peripheral set includes dual 10/100 Ethernet with IEEE 1588 support, dual FlexCAN3 controllers, four DSPI interfaces, six UART/SCI with LIN and IrDA, and dual display control units (DCU) supporting WVGA TFT - all operating within a single 3.0–3.6 V supply and automotive temperature range.

FAQ

What is the maximum operating frequency of the Cortex-A5 core in SVF311R3K1CKU2?

The SVF311R3K1CKU2 features an ARM Cortex-A5 core rated for up to 266 MHz operation, as confirmed in the NXP VYBRIDRSERIESEC datasheet Rev. 8, Section 2.2 (Part Number Format) and Table 2.3 (Orderable Parts). This frequency is guaranteed across the full -40 °C to +85 °C ambient temperature range and 3.0–3.6 V supply voltage. The SVF311R3K1CKU2 does not support the 400 MHz variant found in VF5xxR parts.

Does SVF311R3K1CKU2 include a Cortex-M4 core?

No, SVF311R3K1CKU2 contains only an ARM Cortex-A5 core. Its part number decoding (S-V-F-3-1-1-R3-K1-C-KU2) confirms "1" in the Core field = Cortex-A5 only. Models with M4 integration use "2" (e.g., SVF321R3K2CKU2) or "3" (M4 Primary) in that position. The SVF311R3K1CKU2 datasheet explicitly lists M4 features as "not applicable" for this specific orderable part.

What package type and pin count does SVF311R3K1CKU2 use?

SVF311R3K1CKU2 uses a 176-pin LQFP-EP (Low-Profile Quad Flat Package with Exposed Pad), measuring 24 mm × 24 mm × 1.6 mm with 0.5 mm pitch. This is unambiguously specified in the NXP part numbering guide (Figure 1, "Package" field = KU) and confirmed in Table 2.3 where SVF311R3K1CKU2 is listed with "LQFP-EP 176 24*24*1.6" package description.

Is SVF311R3K1CKU2 qualified for automotive applications?

Yes, SVF311R3K1CKU2 carries automotive qualification: the "S" in its brand field (SVF…) denotes automotive qualification per NXP's internal standards, and its temperature range (-40 °C to +85 °C ambient) meets AEC-Q100 Grade 3 requirements. The datasheet states "S = automotive qualified" in Section 2.2, and handling ratings (ESD, thermal, moisture) align with AEC-Q100 test conditions.

What memory interfaces are supported by SVF311R3K1CKU2?

SVF311R3K1CKU2 supports DDR3/LPDDR2 (via 8/16-bit DRAM controller), 8/16-bit NAND Flash with ECC, dual Quad SPI with XIP, and 8/16/32-bit FlexBus external interface. These are documented in Section 9.5 of the VYBRIDRSERIESEC datasheet. Notably, ECC is supported only for 8-bit NAND and 8-bit DRAM modes - not for 16-bit configurations - a critical constraint for system-level error correction planning.
