NXP Semiconductors MCIMX6Y1DVK05AA

Overview

MCIMX6Y1DVK05AA from NXP Semiconductors is a single-core Arm Cortex-A7 application processor operating at 528 MHz, featuring basic security (TrustZone, HABv4, SNVS), one FlexCAN interface, dual USB OTG with integrated PHY, eight UARTs, three SAI audio interfaces, and ESAI - all in a 9 × 9 mm, 0.5 mm pitch MAPBGA package. It targets cost-sensitive, power-efficient embedded applications including industrial gateways and secure HMI terminals.

For engineers reviewing the MCIMX6Y1DVK05AA datasheet, MCIMX6Y1DVK05AA pinout, MCIMX6Y1DVK05AA application, or MCIMX6Y1DVK05AA equivalent, key selection criteria include its 528 MHz Cortex-A7 core, 9 × 9 mm MAPBGA footprint, single CAN channel, absence of LCD/CSI interfaces, and commercial temperature range (0 to +95 °C).

Technical Context

The MCIMX6Y1DVK05AA implements Arm TrustZone for hardware-enforced secure world isolation and uses Advanced High Assurance Boot (A-HAB) with AES-128, SHA-1, and SHA-256 acceleration. Its memory subsystem includes 32 KB L1 instruction and data caches, 128 KB unified L2 cache, 128 KB OCRAM, and boot ROM with HAB support.

Peripherals are routed via a shared AXI/AHB fabric with configurable I/O muxing: two 10/100 Mbps Ethernet controllers are not enabled on this variant; instead, it provides one FlexCAN, dual USB OTG, three SAI, ESAI, four I²C, four eCSPI, eight PWM, and two 12-bit ADC channels (total 10 inputs), all compliant with IEEE 1588 timing where applicable.

FAQ

What is the maximum operating frequency of the MCIMX6Y1DVK05AA?

The MCIMX6Y1DVK05AA operates at a fixed maximum frequency of 528 MHz. This speed is factory-fused and cannot be overclocked; it balances performance and power efficiency for commercial-grade embedded applications. The MCIMX6Y1DVK05AA does not support dynamic frequency scaling beyond its rated 528 MHz, unlike higher-tier i.MX 6ULL variants such as MCIMX6Y2DVK09AB (900 MHz).

Does the MCIMX6Y1DVK05AA support secure boot, and what cryptographic algorithms are hardware-accelerated?

Yes, the MCIMX6Y1DVK05AA supports secure boot via Advanced High Assurance Boot (A-HABv4). It includes hardware acceleration for AES-128 encryption/decryption, SHA-1, and SHA-256 hashing - all used during image authentication and decryption. The MCIMX6Y1DVK05AA leverages SNVS and CSU modules to enforce trust boundaries, ensuring only cryptographically signed firmware executes.

Can the MCIMX6Y1DVK05AA drive an LCD display or connect to a camera sensor?

No, the MCIMX6Y1DVK05AA explicitly omits LCDIF and CSI interfaces per its ordering specification. These functions are disabled in silicon and not accessible via pinmux or software enablement. For display or camera support, engineers must select MCIMX6Y2DVK05AA or MCIMX6Y7DVK05AA - the MCIMX6Y1DVK05AA is optimized for headless or audio-centric applications.

How many UART interfaces does the MCIMX6Y1DVK05AA provide, and what is their maximum baud rate?

The MCIMX6Y1DVK05AA provides eight UART interfaces, each supporting up to 5.0 Mbps. These UARTs include hardware flow control (RTS/CTS), RS-485 multidrop mode, and RS-232 level translation capability. All eight UARTs are fully functional and simultaneously usable in the MCIMX6Y1DVK05AA, making it well-suited for multi-protocol industrial communication gateways.

What is the package type and pin count of the MCIMX6Y1DVK05AA?

The MCIMX6Y1DVK05AA uses a 9 × 9 mm, 0.5 mm pitch MAPBGA package with 289 solder balls. This compact footprint is defined in Section 6.2 of the IMX6ULLCEC datasheet and shares mechanical compatibility with other 9 mm i.MX 6ULL variants like MCIMX6Y7DVK05AA. The MCIMX6Y1DVK05AA's pinout is distinct from the 14 × 14 mm variants and requires dedicated PCB layout.
