AM1808EZCED4

Overview

The AM1808EZCED4 is a low-power microprocessor based on the ARM926EJ-S core, operating at frequencies up to 456 MHz. It features a 32-bit RISC architecture with 16KB instruction and data caches, 8KB RAM for the vector table, and 64KB ROM. The device includes two external memory interfaces: EMIFA supporting NOR, NAND, and SDRAM, and a DDR2/Mobile DDR controller. Integrated peripherals include an Ethernet MAC (EMAC), USB 2.0 OTG, SATA, PRU subsystem, and various serial interfaces like UART, SPI, and I2C.

Feature Summary

• Integrates a Programmable Real-Time Unit (PRU) subsystem with two independent cores for deterministic control tasks.
• Provides dual external memory interfaces including EMIFA for asynchronous memories and a dedicated DDR2/mDDR controller.
