It supports DDR3/DDR3L at 400 MHz (800 Mbps), includes 256KB L2 cache with ECC, and targets industrial automation and connected HMI applications.
For engineers reviewing the AM3357ZCZD72 datasheet, AM3357ZCZD72 pinout, AM3357ZCZD72 application, or AM3357ZCZD72 equivalent, this page delivers verified specifications, package mapping, real-time industrial protocol support, memory interface timing, and validated alternative options for embedded SoC selection.
Technical Context
The AM3357ZCZD72 implements a single-core ARM Cortex-A8 CPU with NEON SIMD coprocessor, 32KB L1 instruction and 32KB L1 data cache (parity-protected), and 256KB L2 cache with ECC. Its PRU-ICSS subsystem contains two independent 200-MHz programmable real-time units with 8KB instruction RAM, 8KB data RAM, and 12KB shared RAM-enabling deterministic EtherCAT frame processing without CPU intervention.
It integrates dual gigabit Ethernet MACs supporting MII/RMII/RGMII/MDIO, IEEE 1588v1 PTP, and an on-chip switch; a 16-bit EMIF for DDR3/DDR3L up to 800 Mbps; and a GPMC supporting NAND/NOR/SRAM with BCH 4-/8-/16-bit ECC. The device operates across –40°C to 90°C and uses a 324-ball NFBGA (ZCZ) package with 0.80-mm pitch.
