Overview

MCIMX6Y1CVK05AB from NXP Semiconductors is an industrial-grade Arm Cortex-A7 single-core applications processor operating at 528 MHz, featuring basic security (TrustZone, HABv4, SNVS), one FlexCAN interface, dual USB OTG with integrated PHY, eight UARTs, and four I²C interfaces. It integrates 128 KB L2 cache, 128 KB OCRAM, and supports DDR3/DDR3L/LPDDR2, NAND/NOR/eMMC, and Quad SPI memory interfaces - deployed in IoT gateways and secure HMI terminals.

For engineers reviewing the MCIMX6Y1CVK05AB datasheet, MCIMX6Y1CVK05AB pinout, MCIMX6Y1CVK05AB application, or MCIMX6Y1CVK05AB equivalent, key selection criteria include its 9 × 9 mm MAPBGA package with 0.5 mm pitch, -40°C to +105°C junction temperature rating, absence of LCD/CSI interfaces, and confirmed support for AES-128/SHA-256 hardware acceleration, dual USB OTG, and single 10/100 Ethernet controller.

Technical Context

The MCIMX6Y1CVK05AB implements a single Arm Cortex-A7 core with TrustZone, 32 KB L1 instruction and data caches, and 128 KB unified L2 cache. Its memory subsystem includes boot ROM (96 KB), 128 KB on-chip RAM (OCRAM), and multilevel external memory support including DDR3-800, LPDDR2-800, and NAND with up to 40-bit BCH ECC.

Peripherals are managed via a centralized clock control module (CCM), general power controller (GPC), and system reset controller (SRC). It integrates dedicated accelerators - ASRC for asynchronous audio sample rate conversion, PXP for pixel processing (rotation, CSC, alpha-blending), and SDMA for offloading data movement - all coordinated under the GIC supporting 128 interrupts.

Key Specifications

Pinout & Package

MCIMX6Y1CVK05AB uses a 9 × 9 mm MAPBGA package with 0.5 mm pitch and 289 I/O balls. Pin assignments follow the i.MX 6ULL 9 mm package mapping defined in Section 6.2 of IMX6ULLIEC Rev. 1.2, with ball functions assigned per signal multiplexing groups (e.g., UART3_TXD on ball A12, CAN1_RX on ball D10, ENET1_MDC on ball E1).

FAQ

What is the maximum operating frequency of the MCIMX6Y1CVK05AB?

The MCIMX6Y1CVK05AB operates at a maximum core frequency of 528 MHz, validated across the full industrial temperature range (-40°C to +105°C). This speed is fixed per the part number suffix '05' and confirmed in Table 1 of the IMX6ULLIEC datasheet. The MCIMX6Y1CVK05AB does not support dynamic frequency scaling beyond this rated speed, and overclocking is not permitted or characterized.

Does the MCIMX6Y1CVK05AB support LCD or camera interfaces?

No, the MCIMX6Y1CVK05AB explicitly omits LCD and CSI interfaces, as stated in its ordering information table (page 4 of IMX6ULLIEC Rev. 1.2). This distinguishes it from MCIMX6Y2 variants which include EPDC and CSI blocks. The MCIMX6Y1CVK05AB retains only the parallel display port capability via its general-purpose GPIO muxing, but lacks dedicated LCDIF or CSI hardware accelerators.

What security features are implemented in the MCIMX6Y1CVK05AB?

The MCIMX6Y1CVK05AB includes hardware-enforced security features: Arm TrustZone isolation, Advanced High Assurance Boot (HABv4) with AES-128/SHA-1/SHA-256 acceleration, Secure Non-Volatile Storage (SNVS) with tamper detection, and Central Security Unit (CSU) policy enforcement. These are confirmed in Sections 1.2 and 9 of the IMX6ULLIEC datasheet and apply directly to the MCIMX6Y1CVK05AB as a "Basic security" variant.

Which memory types does the MCIMX6Y1CVK05AB support?

The MCIMX6Y1CVK05AB supports LPDDR2-800, DDR3-800, DDR3L-800 (all 16-bit), Raw and Managed NAND (with up to 40-bit BCH ECC), NOR Flash, eMMC 4.41/4.5, and Quad SPI NOR. These interfaces are documented in Section 7 and Table 2 of the IMX6ULLIEC datasheet and are fully enabled in the MCIMX6Y1CVK05AB's silicon configuration.

Is the MCIMX6Y1CVK05AB pin-compatible with other i.MX 6ULL variants?

No, the MCIMX6Y1CVK05AB is not pin-compatible with 14 × 14 mm variants like MCIMX6Y1CVM05AB due to its 9 × 9 mm MAPBGA package with 0.5 mm pitch and 289-ball layout. Pin mappings differ significantly between the two footprints, and direct PCB replacement is not possible. The MCIMX6Y1CVK05AB requires its own dedicated layout per Section 6.2 of IMX6ULLIEC.
