MCIMX7U3DVK07SD

The MCIMX7U3DVK07SD is an NXP i.MX 7ULP family applications processor configured for consumer-class, power-sensitive designs. It combines an ARM® Cortex®-A7 application domain with an ARM® Cortex®-M4 real-time domain to deliver a heterogeneous multicore architecture for mixed rich-OS and deterministic tasks.

With an overdrive application frequency of 720 MHz, low-power run modes, integrated graphics and a compact 361‑VFBGA (10×10) package, this device targets compact embedded consumer applications that require efficient performance, secure boot and wide peripheral integration.

Key Features

• Heterogeneous Multicore Architecture — ARM Cortex‑A7 application domain (up to 720 MHz overdrive) with NEON SIMD and FPU, paired with an ARM Cortex‑M4 real‑time domain for deterministic control.
• Processor Performance — Dual‑core, 32‑bit Cortex‑A7 configuration with 32 KB instruction and data caches and 256 KB L2 cache to support OS-based applications.
• Real‑Time Domain — Cortex‑M4 real‑time processor optimized for low leakage with separate power and clock domains; multiple low‑power run modes supported.
• On‑Chip and External Memory — On‑chip RAM (256 KB) and tightly coupled RAM (256 KB in switchable 32 KB blocks), plus 16/32‑bit LPDDR2/LPDDR3 external memory interface running at 380.16 MHz.
• Graphics and Display — Integrated graphics acceleration (GC7000 NanoULTRA noted in product documentation) and MIPI‑DSI display interface for rich UI implementations.
• Security and Boot — Hardware crypto/TRNG, secure boot, CAAM/LTC engines, eFuses/OTP and secure fuse features to enable authenticated boot and runtime security functions.
• Connectivity and Peripherals — Multiple serial interfaces including four I2C, four UARTs with flow control, two LPSPI, FlexIO, SD 3.0/MMC 5.0, dual USB 2.0 ports (with HSIC referenced), and serial flash support (x4/x8).
• Timers and System — Multiple 32‑bit general‑purpose timers, 64‑bit timer, watchdog timers and system timers suitable for control and scheduling tasks.
• Package and Mounting — 361‑VFBGA (10×10 mm) surface‑mount package for compact board integration.
• Operating Range and Compliance — Consumer qualification with operating temperature 0 °C to 95 °C and RoHS compliant status.

Typical Applications

• Consumer IoT and Smart Devices — Rich OS-driven user interfaces and connected features using the Cortex‑A7 domain with graphics acceleration and MIPI‑DSI display support.
• Low‑Power Embedded Controllers — Battery‑ or power‑sensitive designs leveraging the low‑leakage Cortex‑M4 real‑time domain for deterministic control and energy efficiency.
• Multimedia Interfaces — Applications requiring display and multimedia acceleration paired with external LPDDR2/LPDDR3 memory and serial storage (eMMC/serial flash).
• Secure Consumer Products — Devices needing hardware root‑of‑trust, secure boot and cryptographic engines for authenticated firmware and secure transactions.

Unique Advantages

• Heterogeneous processing balance — Separates rich application workloads on Cortex‑A7 from deterministic real‑time tasks on Cortex‑M4, enabling efficient, task‑appropriate power use.
• Integrated security primitives — Crypto/TRNG, secure boot and eFuse/OTP features reduce BOM and simplify implementation of trusted boot and encryption functions.
• Compact package, simplified integration — 361‑VFBGA (10×10) packaging minimizes PCB footprint while keeping a broad set of peripherals available for system designs.
• Memory and storage flexibility — On‑chip RAM plus LPDDR2/LPDDR3 external memory support and serial/eMMC interfaces accommodate implementations from lightweight to memory‑rich applications.
• Broad peripheral mix — Comprehensive serial interfaces (I2C, UART, SPI, FlexIO, SD/MMC, USB) provide design flexibility and reduce the need for external bridge ICs.
• Consumer‑oriented thermal range — Specified 0 °C to 95 °C operating range for typical consumer deployments.
