NXP Semiconductors SVF511R3K2CMK4

Overview

SVF511R3K2CMK4 from NXP Semiconductors is a dual-core heterogeneous application processor integrating an ARM Cortex-A5 core (400 MHz) and no Cortex-M4 core, 512 KB on-chip SRAM with ECC, 96 KB boot ROM, and support for LPDDR2/DDR3 memory up to 400 MHz - deployed in industrial HMI, gateway controllers, and secure edge nodes requiring deterministic real-time response alongside rich OS capability.

For engineers reviewing the SVF511R3K2CMK4 datasheet, SVF511R3K2CMK4 pinout, SVF511R3K2CMK4 application, or SVF511R3K2CMK4 equivalent, key selection criteria include A5-only operation at 400 MHz, absence of M4 co-processor and L2 cache, OpenVG GPU exclusion, VADC inclusion, and 364-pin MAP BGA (17×17 mm, 0.8 mm pitch) packaging - all confirmed per NXP's VF5xxR Rev. 8 datasheet.

Technical Context

The SVF511R3K2CMK4 implements a single ARM Cortex-A5 core without M4 companion, executing Linux or RTOS with full TrustZone security isolation. It relies on internal PLLs (including 528 MHz System PLL and 480 MHz USB PLL) and dual crystal oscillators (24 MHz and 32 kHz) for clock generation, with hardware CRC, watchdog, and Secure Non-Volatile Storage (SNVS) enabling robust system-level integrity.

Memory subsystem includes 8/16-bit DRAM controller supporting LPDDR2/DDR3 (ECC enabled only for 8-bit mode), dual QuadSPI with XIP, 8/16-bit NAND Flash controller with ECC, and FlexBus for external parallel interfaces - all coordinated by a dual DMA controller with 32 channels and DMAMUX routing.

Key Specifications

Pinout & Package

SVF511R3K2CMK4 uses a 364-ball fine-pitch MAP BGA package (17 mm × 17 mm, 0.8 mm pitch, 1.5 mm height) with exposed thermal pad. Pin functions are defined across multiple banks (GPIO, DDR, FlexBus, USB, Ethernet, etc.) and require precise PCB layout per NXP's recommended ball map and power sequencing guidelines.

FAQ

What is the maximum operating frequency of the ARM Cortex-A5 core in SVF511R3K2CMK4?

The SVF511R3K2CMK4 features an ARM Cortex-A5 core rated for up to 400 MHz operation under specified voltage (3.0–3.6 V) and temperature (–40 °C to +85 °C) conditions. This speed is guaranteed per NXP's VF5xxR Rev. 8 datasheet and enables Linux kernel execution with sufficient headroom for protocol stacks and application logic. The SVF511R3K2CMK4 does not include an M4 co-processor, so all real-time tasks must be scheduled within the A5 environment or delegated to hardware accelerators like the FTM timers or CRC module.

Does SVF511R3K2CMK4 include an ARM Cortex-M4 core?

No, SVF511R3K2CMK4 is an A5-only variant within the VF5xxR family and does not integrate an ARM Cortex-M4 core. Its part number decoding confirms "1" in the Core field (VF511R3K2CMK4), indicating Cortex-A5 primary with no M4 companion. This distinguishes it from SVF521R3K2CMK4 (A5+M4) and SVF531R3K2CMK4 (M4-primary). Real-time tasks must therefore rely on A5 scheduling, hardware timers (PIT, LPTMR), or peripheral DMA engines rather than dedicated M4 execution.

What memory interfaces are supported by SVF511R3K2CMK4?

SVF511R3K2CMK4 supports LPDDR2/DDR3 memory via an 8/16-bit DRAM controller (up to 400 MHz, ECC enabled for 8-bit only), dual QuadSPI with XIP capability, 8/16-bit NAND Flash with ECC (8-bit only), and 8/16/32-bit FlexBus for parallel peripherals. It does not include L2 cache - confirmed by part number "1" in Memory Option field (SVF511R3K2CMK4), meaning standard 1.5 MB on-chip SRAM configuration (512 KB SRAM + 96 KB ROM + graphics SRAM allocation not present in this variant).

Is OpenVG GPU included in SVF511R3K2CMK4?

No, SVF511R3K2CMK4 excludes the OpenVG GPU. Its part number ends in "K2", where the Graphics field is "1" (SVF511R3K2CMK4), indicating "No Open VG". This contrasts with SVF512R3K2CMK4 (Graphics = "2"), which integrates the OpenVG GPU for 2D vector graphics acceleration. For SVF511R3K2CMK4, display output relies solely on the Dual Display Control Unit (DCU) driving TFT panels up to WVGA resolution without hardware-accelerated compositing or path rendering.

What is the package type and pin count of SVF511R3K2CMK4?

SVF511R3K2CMK4 uses a 364-ball MAP BGA package measuring 17 mm × 17 mm with 0.8 mm pitch and 1.5 mm height, as specified in NXP's VF5xxR datasheet section 11.1 and ordering table. The "MK" in the part number explicitly denotes this 364-pin MAP BGA variant (vs. "KU" for 176-pin LQFP). Thermal pad exposure and ball map alignment must follow NXP's mechanical drawing MK4, and PCB layout must observe strict power plane segmentation and DDR signal routing rules per the reference design guidelines.
