AM1808EZCEA3

The AM1808EZCEA3 is a Sitara AM18xx series ARM926EJ-S microprocessor IC delivering a 32‑bit single core at 375 MHz in a 361‑ball NFBGA (13×13 mm) package. It is an industrial‑grade embedded MPU with integrated memory controllers, a programmable real‑time unit subsystem (PRUSS), and a broad set of I/O suitable for connected and control applications.

Designed for systems requiring real‑time control, legacy peripheral support and storage/connectivity interfaces, the AM1808EZCEA3 combines processing, peripheral integration and temperature‑rated operation (‑40 °C to 105 °C) to support robust embedded designs.

Key Features

• Core ARM926EJ‑S 32‑bit RISC core running at 375 MHz for general‑purpose embedded processing.
• Memory and On‑Chip RAM DDR2/mDDR and LPDDR memory controller support; on‑chip resources include caches and internal RAM and ROM as specified by the Sitara AM18xx family for fast local storage and deterministic code execution.
• Programmable Real‑Time Unit Subsystem (PRUSS) Integrated PRU subsystem providing deterministic real‑time processing and offload capabilities for timing‑critical tasks.
• Interfaces – Networking and Storage 10/100 Mbps Ethernet MAC, SATA 3 Gbps host interface and MMC/SD/SDIO support enable wired networking and local storage options.
• USB and Legacy USB Host Integrated USB 2.0 + PHY and USB 1.1 + PHY interfaces provide host/device connectivity options for peripherals and legacy USB devices.
• Display and Multimedia LCD controller support for display interfacing and multimedia card interface with secure data I/O (SDIO).
• Peripheral Set Multiple UARTs (configurable 16550 type), SPI, I2C, MMC/SD, MMC/SDIO and audio serial port connectivity for diverse peripheral integration.
• Enhanced DMA and Timers EDMA3 enhanced DMA controller and multiple general‑purpose timers and watchdog timer support for efficient data movement and system timing.
• Package and Environmental 361‑ball NFBGA (13×13 mm) surface‑mount package, industrial grade operation from ‑40 °C to 105 °C, RoHS compliant.

Typical Applications

• Industrial Control Real‑time PRU subsystem, deterministic timers and industrial temperature range make the device suitable for embedded control, PLC adjuncts and motion or motor control interfaces.
• Embedded Networking Appliances Integrated 10/100 Mbps Ethernet MAC and USB interfaces allow use in routers, gateways and networked instrumentation.
• HMI and Display Systems LCD controller and multiple serial interfaces support human‑machine interfaces, instrument displays and operator panels.
• Local Storage and Multimedia Devices SATA 3 Gbps plus MMC/SD/SDIO support enable devices that require local storage, logging or multimedia card expansion.

Unique Advantages

• Integrated Real‑Time Offload: The PRU subsystem provides dedicated, programmable real‑time cores to handle time‑sensitive tasks without burdening the main ARM core.
• Broad I/O and Storage Options: On‑chip Ethernet, SATA, USB 2.0/1.1, MMC/SD and multiple serial buses reduce external controller requirements and simplify BOM.
• Memory Flexibility: Support for DDR2/mDDR and LPDDR memory types enables scalable system memory configurations for different application needs.
• Industrial Temperature Range: Rated for operation from ‑40 °C to 105 °C to meet demanding environmental requirements in industrial deployments.
• Compact, Surface‑Mount Package: 361‑ball NFBGA (13×13 mm) package balances a high pin count with a compact footprint for space‑constrained boards.
• Enhanced DMA and Timer Resources: EDMA3 and multiple timers support efficient data movement and deterministic system timing for embedded applications.

Why Choose AM1808EZCEA3?

The AM1808EZCEA3 positions itself as a highly integrated industrial embedded microprocessor that couples an ARM926EJ‑S core with a programmable real‑time subsystem, broad peripheral connectivity and flexible memory interfacing. This combination supports designs that require both general‑purpose processing and deterministic I/O or control tasks.

Engineers building industrial controllers, networked appliances, HMI panels or storage‑enabled embedded systems can leverage the device’s integrated interfaces, real‑time offload and industrial temperature rating to simplify designs, reduce external components and meet long‑term operational needs.
