Core compute and integration for connected control
The AM3351BZCE30 is a single-core ARM Cortex-A8 microprocessor from the Sitara family, clocked at 300 MHz with a 32-bit bus width and a NEON SIMD coprocessor for multimedia acceleration. It integrates a USB 2.0 port with on-chip PHY and a 10/100/1000 Mbps Ethernet MAC with its own PHY, so a two-interface board (USB device + Gigabit Ethernet) needs no external transceiver for the MAC side. Memory controller supports LPDDR, DDR2, DDR3, and DDR3L — the same PCB layout can serve a cost-optimised DDR2 build or a higher-bandwidth DDR3 design by swapping the memory devices and adjusting the termination.
Peripheral set and security for industrial HMI
Additional interfaces include I2C, McASP, McSPI, MMC/SD/SDIO, and UART, covering the typical sensor bus, audio codec, and SD-card storage needs of a panel-mounted HMI or gateway. On-chip display and touchscreen controllers drive an LCD panel directly, and the graphics acceleration block offloads 2D compositing from the Cortex-A8 core. A hardware security block with cryptography and a random number generator supports secure boot and encrypted communication without loading the main CPU.
Package, temperature, and compliance
I/O voltage rails are 1.8 V and 3.3 V, matching common DDR and peripheral supplies without external level shifters on most interfaces.
