Core architecture and clock budget for the BOM line
The MCIMX6L3EVN10AB is a single-core ARM Cortex-A9 application processor from the NXP i.MX6SL series, running at 1.0 GHz. This is the maximum core frequency; actual throughput depends on the flash wait-state profile and the memory controller configuration. The NEON SIMD coprocessor handles single-instruction multiple-data (SIMD) operations for multimedia and signal-processing tasks without loading the Cortex-A9 pipeline. Graphics acceleration is present on-die, driving the LCD display controller. Memory controller supports LPDDR2, LVDDR3, and DDR3 — the board designer picks the memory type that matches the target cost and speed grade. The 432-MAPBGA (13x13 mm) package requires a 4-layer PCB minimum for fan-out of the 0.50 mm pitch balls.
Peripheral set and connectivity for system integration
The single 10/100 Ethernet MAC with on-chip PHY provides wired networking without an external magnetics module — the PHY is internal, so only the RJ45 connector and isolation transformer are needed on the board. Additional interfaces include AC97, I2C, I2S, MMC/SD/SDIO, SPI, SSI, and UART — covering audio codec, touch controller, storage, and serial debug. The I/O voltage rails are 1.2 V, 1.8 V, and 3.0 V, requiring three separate supply domains on the PCB. Security features are hardware-enforced: ARM TrustZone, boot security, cryptography engine, secure fuse box, secure JTAG, secure memory, secure RTC, and tamper detection. These blocks run independently of the Cortex-A9 core, so secure boot and key storage do not consume application MIPS.
An outdoor IoT gateway or factory controller that sees 85°C on a summer production floor still has 20°C of margin before the silicon junction hits the rated limit. Production status is active per NXP's lifecycle record. The part is ROHS3 compliant, meeting the EU RoHS exemption 7(c)-I for lead in solder.
