AM1808EZCED4

The AM1808EZCED4 is a Sitara™ ARM926EJ-S based microprocessor operating at 456 MHz, provided in a 361‑ball NFBGA (13×13) surface-mount package. Designed for embedded and industrial applications, it delivers a single 32‑bit core with a rich set of peripheral interfaces for connectivity, storage and display.

With industrial-grade temperature capability and integrated controllers for DDR2/LPDDR memory, Ethernet, USB, SATA and LCD, the AM1808EZCED4 targets embedded designs that require deterministic control, broad I/O integration and hardened operating range.

Key Features

• Core and Performance – ARM926EJ‑S single 32‑bit core running at 456 MHz, offering a RISC architecture suitable for real‑time and control-oriented embedded tasks.
• Memory Interfaces – Integrated memory controllers for LPDDR and DDR2, plus external memory interfaces supporting NOR and NAND configurations for flexible system memory design.
• Programmable Real‑Time Unit Subsystem (PRUSS) – Dedicated PRU subsystem with two independent programmable real‑time cores and on‑chip memory for offloading time‑critical tasks; PRUSS can be disabled via software to reduce power.
• High‑speed I/O and Storage – Built‑in SATA 3 Gbps interface and a 10/100 Mbps Ethernet MAC for networking and storage gateway applications.
• USB and Host Interfaces – Integrated USB 1.1 (OHCI host) and USB 2.0 OTG support with on‑chip PHYs for host and device connectivity.
• Display and Audio – LCD controller for drive of display panels and multimedia interfaces including MMC/SD with SDIO for external storage and multimedia cards.
• Serial and Peripheral Interfaces – Multiple UARTs, SPI modules, I2C, and multichannel audio serial port options for sensor, control and user‑interface connections.
• System and DMA – Enhanced DMA controller (EDMA3) with many channels and flexible transfer options to reduce CPU overhead for data movement.
• Package and Temperature – 361‑NFBGA (13×13) surface‑mount package rated for industrial operation from −40 °C to 90 °C.
• Environmental Compliance – RoHS compliant.

Typical Applications

• Industrial Control – Deterministic real‑time control using the PRU subsystem and ARM926EJ‑S core for motor control, PLCs and factory automation.
• Networking Appliances – Gateway and edge devices leveraging integrated 10/100 Mbps Ethernet and USB 2.0 for connectivity and device aggregation.
• Embedded Storage & Media – Storage controllers and media players utilizing the SATA 3 Gbps interface and MMC/SD with SDIO support for local storage.
• Human‑Machine Interfaces (HMIs) – Systems requiring LCD display control and multiple serial peripherals for touch panels, displays and operator interfaces.

Unique Advantages

• Highly integrated connectivity: Ethernet, SATA, USB 1.1/2.0 with PHYs and multiple serial buses reduce external components and simplify board design.
• Real‑time offload capability: The PRU subsystem provides independent real‑time processing cores to handle deterministic tasks without burdening the main CPU.
• Flexible memory support: On‑chip controllers for DDR2 and LPDDR plus external memory interface options enable scalable system memory architectures.
• Robust for industrial environments: Industrial temperature rating (−40 °C to 90 °C) and a compact 361‑NFBGA package support harsh operating conditions and high‑density designs.
• Efficient data movement: Enhanced DMA (EDMA3) with a large number of channels lowers CPU overhead for high‑throughput data transfers.
• Standards‑based interfaces: Support for common interfaces (UART, SPI, I2C, MMC/SDIO) enables straightforward integration with sensors, peripherals and legacy modules.
