MCIMX7U3DVK07SD

Overview

The MCIMX7U3DVK07SD is an i.MX 7ULP Applications Processor optimized for power-sensitive consumer applications. It features a heterogeneous multicore architecture with an ARM Cortex-A7 core running at 720 MHz and an ARM Cortex-M4 core running at 200 MHz. The device lacks GPU support, utilizing the GC320 composition processing core instead. It includes 256 KB of RAM in the application domain and 256 KB of tightly coupled RAM in the real-time domain. The processor supports LPDDR2/LPDDR3 external memory and eMMC 5.0 interfaces. It operates within a commercial temperature range of 0 to +95 °C and is housed in a 10 mm x 10 mm BGA package.

Procurement Notes

Verify the specific part number suffix against official NXP documentation to confirm hardware configuration. Ensure compatibility with required operating systems and peripheral interfaces before integration. Cross-reference electrical specifications and thermal ratings with the latest datasheet revisions to validate performance under intended load conditions.

Selection Notes

Select this component when GPU acceleration is unnecessary to reduce cost and power consumption. Ideal for applications requiring deterministic real-time control alongside basic user interface rendering. Consider the limited internal memory capacity and verify external memory requirements during system design.

Part Context

This part belongs to the i.MX 7ULP family, which targets ultra-low-power wearable and IoT markets. It shares the core heterogeneous architecture with other variants but differs in memory size, interface availability, and graphics capabilities. The VK suffix indicates a specific package type and speed grade within the consumer tier.
