NXP Semiconductors MCIMX7U5CVP06SD

Overview

MCIMX7U5CVP06SD from NXP Semiconductors is an industrial-grade heterogeneous multicore applications processor integrating an ARM Cortex-A7 application domain (650 MHz) and an ARM Cortex-M4 real-time domain (200 MHz), with 256 KB on-chip RAM, GC7000 Nano Ultra GPU-3D and GC320 GPU-2D support, and LPDDR2/LPDDR3 memory interface - deployed in battery-powered HMI, smart sensor gateways, and low-power industrial controllers.

For engineers reviewing the MCIMX7U5CVP06SD datasheet, MCIMX7U5CVP06SD pinout, MCIMX7U5CVP06SD application, or MCIMX7U5CVP06SD equivalent, key selection criteria include asymmetric power-domain isolation, dual-core security boot (HAB/uHAB), 14×14 mm 0.5 mm pitch BGA package (VP), and verified support for eMMC 5.0, Quad SPI, and dual 12-bit ADC/DAC in real-time domain.

Technical Context

The MCIMX7U5CVP06SD implements strict hardware-enforced domain separation: the Cortex-A7 domain (AD) handles rich OS execution with NEON, FPU, 256 KB L2 cache, and TrustZone, while the Cortex-M4 domain (RT) operates independently with dedicated 256 KB TCM, low-leakage design, and real-time peripherals including LPUART, LPSPI, and LPIT timers. Both domains share a tightly coupled AMBA NIC crossbar but maintain isolated clocking, power rails, and peripheral assignment.

Security is implemented at silicon level via CAAM (application domain) and LTC/MMCAU (real-time domain), supporting AES-128/256, SHA-256, TRNG, and tamper detection. Power management includes seven defined modes (HSRUN/RUN/VLPR/STOP/VLPS/LLS/VLLS), with VLPR enabling 48 MHz operation in both cores for ultra-low-power wake-up scenarios.

Key Specifications

Pinout & Package

MCIMX7U5CVP06SD uses a 14 mm × 14 mm, 0.5 mm pitch BGA package (VP suffix) with 361 balls. Pin assignments follow NXP's standardized i.MX 7ULP VP ball map (Document IMX7ULPIECB2, Rev. 1, Section 10.1.2), supporting dedicated power domains (VDD_A7, VDD_M4, VDDIO), DDR interface (DQ[31:0], DQS[3:0]), and dual-domain I/O (LPUART0–7, LPSPI0–3, LPI2C0–7).

FAQ

What is the maximum operating frequency of the Cortex-A7 core in MCIMX7U5CVP06SD?

The Cortex-A7 core in MCIMX7U5CVP06SD operates at up to 650 MHz in High-Speed Run (HSRUN) mode, confirmed in the i.MX 7ULP Data Sheet (Rev. 1, Section "Ordering Information") and validated across −40 °C to +105 °C junction temperature range. This frequency is sustained only when VDD_A7_1P0 is regulated to 1.0 V ±2% and thermal limits are maintained. MCIMX7U5CVP06SD does not support overclocking beyond this specification.

Does MCIMX7U5CVP06SD support secure boot for both processor domains?

Yes, MCIMX7U5CVP06SD implements dual-domain secure boot: High Assurance Boot (HAB) secures the Cortex-A7 domain, while ultra-High Assurance Boot (uHAB) secures the Cortex-M4 domain. Both use on-chip CAAM (A7) and LTC (M4) engines to verify digital signatures of boot images stored in eMMC or Quad SPI flash, as documented in the i.MX 7ULP Security Reference Manual. MCIMX7U5CVP06SD requires fused eFuses to enable permanent secure boot enforcement.

What GPU capabilities are enabled in MCIMX7U5CVP06SD that differ from MCIMX7U3CVP06SD?

MCIMX7U5CVP06SD includes full GC7000 Nano Ultra GPU-3D and GC320 GPU-2D support, enabling OpenGL ES 2.0/1.1, OpenVG 1.1, and GLSL shading - capabilities absent in MCIMX7U3CVP06SD, which disables both GPUs at silicon level. This difference is explicitly defined in the i.MX 7ULP ordering information table (Rev. 1, p.3), where "GPU-2D, GPU-3D supported" is listed only for MCIMX7U5CVP06SD.

Can MCIMX7U5CVP06SD operate its Cortex-M4 domain independently while the Cortex-A7 domain is powered down?

Yes, MCIMX7U5CVP06SD supports full domain autonomy: the Cortex-M4 domain can remain fully active - running code from TCM, sampling ADCs, communicating via LPUART/LPSPI, and generating LPIT interrupts - while the Cortex-A7 domain is in STOP or VLLS mode. This is enabled by independent power domains (VDD_M4, VDDIO_RT), dedicated clocks (FIRC, IRC1K), and hardware-isolated peripherals, as specified in Section 4 ("Real-time domain") of the i.MX 7ULP Applications Processor Reference Manual.

What external memory interfaces are supported by MCIMX7U5CVP06SD?

MCIMX7U5CVP06SD supports three external memory interfaces: (1) 16/32-bit LPDDR2/LPDDR3 at 271.5 MHz (2.17 GB/s), (2) eMMC 5.0 host interface with HS400 mode support, and (3) Quad SPI flash interface with OTFAD (On-The-Fly AES Decryption). These are electrically and logically distinct - no shared pins - and are documented in Sections 3.1.2, 3.1.3, and 4.1.2 of the i.MX 7ULP Applications Processor Reference Manual. MCIMX7U5CVP06SD does not support DDR3, DDR4, or parallel NOR/NAND.
