AM1808EZWTD4

The AM1808EZWTD4 is a Sitara AM18xx series ARM microprocessor featuring a single ARM926EJ‑S 32‑bit core clocked at 456 MHz. It is designed for embedded and industrial applications that require a compact, highly integrated MPU with a broad set of peripheral interfaces and real‑time capabilities.

With integrated memory controllers, storage and connectivity interfaces, and a programmable real‑time unit subsystem, the AM1808EZWTD4 targets systems that need combined control, I/O and data‑movement capabilities in an industrial temperature grade package.

Key Features

• Core Single ARM926EJ‑S 32‑bit core running at 456 MHz, supporting 32‑bit and 16‑bit (Thumb) instruction sets and ARM Jazelle technology.
• Memory and DMA On‑chip memory architecture includes instruction and data caches plus on‑chip RAM and ROM; external memory support includes DDR2 and LPDDR controllers and a programmable EDMA3 controller with multiple channels for efficient data movement.
• Real‑time Subsystem (PRUSS) Programmable Real‑Time Unit Subsystem with two independent PRU cores and local instruction/data RAM; the PRUSS can be disabled via software to save power.
• Storage Interfaces Integrated SATA 3 Gbps interface and MMC/SD/SDIO support for storage and removable media applications.
• Connectivity 10/100 Mbps Ethernet MAC, one USB 2.0 (with integrated PHY), and one USB 1.1 OHCI host (with integrated PHY) provide broad networking and peripheral connectivity.
• Peripheral Interfaces Multiple serial interfaces including SPI, I2C, three 16550‑type UART modules, audio serial port, host port interface (HPI), and LCD controller for display subsystems.
• Timers and PWMs Multiple general‑purpose timers, watchdog timer, enhanced capture modules and pulse‑width modulators for control and timing functions.
• Package and Temperature Available in a 361‑ball NFBGA supplier package (361‑NFBGA, 16×16) and listed package case 361‑LFBGA; surface‑mount mounting and industrial operating temperature range of −40 °C to 90 °C.
• Compliance RoHS‑compliant component.

Typical Applications

• Industrial Control Use the AM1808EZWTD4 for embedded controllers requiring deterministic real‑time processing and robust I/O, enabled by the PRU subsystem, timers, and multiple serial interfaces.
• Networking Gateways Leverage the integrated 10/100 Mbps Ethernet MAC, USB 2.0/1.1 with PHY, and SDIO/MMC support for compact networked devices and protocol converters.
• Edge Storage and NAS Clients SATA 3 Gbps and SD/MMC interfaces provide direct support for local storage, removable media and edge data logging applications.
• Human‑Machine Interfaces The built‑in LCD controller and multiple serial interfaces make the device suitable for operator displays and control panels in industrial equipment.

Unique Advantages

• Highly integrated connectivity: Ethernet, USB 2.0/1.1 with PHY, SATA and SD/MMC interfaces reduce external component count and simplify board design.
• Real‑time deterministic processing: PRU subsystem with dedicated instruction and data RAM enables offloading of real‑time tasks from the main CPU.
• Flexible memory support: DDR2 and LPDDR memory controllers provide adaptable external memory options for a range of system capacities.
• Efficient data movement: EDMA3 controller with multiple channels and transfer controllers accelerates large data transfers and peripheral servicing.
• Industrial temperature range: Rated for −40 °C to 90 °C to meet demanding environmental conditions in industrial deployments.
• Compact, manufacturable package: 361‑ball NFBGA (16×16) surface‑mount package supports high‑density system integration.
