The AM335x Sitara processors are a family of devices that include the AM3359, AM3358, AM3357, AM3356, AM3354, AM3352, and AM3351. These processors feature:

Up to 1-GHz Sitara ARM Cortex-A8 32-Bit RISC Processor with NEON SIMD coprocessor, 32KB of L1 instruction and data cache, and 256KB of L2 cache with error correcting code (ECC)
On-Chip Memory: 64KB of general-purpose on-chip memory controller (OCMC) RAM, accessible to all masters, with retention for fast wake-up
External Memory Interfaces: mDDR, DDR2, DDR3, and DDR3L controller with 16-bit data bus, 1GB of total addressable space, and support for one x16 or two x8 memory device configurations
Programmable Real-Time Unit Subsystem and Industrial Communication Subsystem (PRU-ICSS): supports protocols like EtherCAT, PROFIBUS, and PROFINET, with two programmable real-time units (PRUs), 32-bit load/store RISC processor, and 8KB of instruction RAM
Power, Reset, and Clock Management (PRCM) Module: controls entry and exit of stand-by and deep-sleep modes, with integrated 15- to 35-MHz high-frequency oscillator, five ADPLLs, and dynamic voltage frequency scaling (DVFS)
Peripherals: up to two USB 2.0 high-speed DRD ports, up to two industrial gigabit Ethernet MACs, up to two CAN ports, up to two multichannel audio serial ports (McASPs), up to six UARTs, and up to three MMC, SD, SDIO ports
