The NXP MCIMX6U1AVM08AC is a dual-core ARM Cortex-A9 processor from the i.MX6DL family, running at 800 MHz.
Memory interface and peripheral set — sizing the BOM
The memory controller supports LPDDR2, LVDDR3, and DDR3.
Graphics and display — LCD controller on a dual-core MPU
Graphics acceleration is present, and the display controller supports both keypad and LCD interfaces.
Security features — hardware root of trust
The MCIMX6U1AVM08AC includes ARM TrustZone technology, secure boot, cryptography acceleration, a secure real-time clock, and tamper detection. This is the feature set that qualifies it for payment terminals, secure IoT gateways, and medical devices that need to protect patient data. The secure fusebox and secure JTAG prevent debug port access after production, so firmware IP stays locked.
Package and board-level reality — 624-MAPBGA
The part comes in a 624-ball MAPBGA package measuring 21x21 mm.
Lifecycle and supply — active, no LTB on the horizon
For a dual-core Cortex-A9 that has been in the market for years, that stability is valuable — you are not chasing a replacement mid-production.
