AM1808BZWTA3

The AM1808BZWTA3 is a Sitara AM18xx ARM926EJ-S based microprocessor running at 375 MHz in a 361-NFBGA (16×16) surface-mount package. Designed for embedded and industrial applications, it combines a single 32‑bit ARM926EJ‑S core with a rich set of peripheral interfaces and memory controllers to address HMI, networking, storage and real‑time control use cases.

With integrated interfaces for Ethernet, SATA, USB and multiple serial peripherals, along with programmable real‑time units and on‑chip memory, the AM1808BZWTA3 delivers a compact, highly integrated processing solution for mid‑range embedded designs requiring industrial temperature support.

Key Features

• Core and Performance — ARM926EJ‑S 32‑bit RISC core at 375 MHz providing deterministic execution for control and application tasks.
• Programmable Real‑Time Unit Subsystem (PRUSS) — Dedicated PRU subsystem with two independent programmable real‑time cores, small instruction/data RAM per core and real‑time debug support for deterministic I/O and offloaded real‑time processing.
• Memory and Cache — On‑chip memory and cache architecture including 128 KB of on‑chip memory, 16 KB instruction cache and 16 KB data cache, plus support for LPDDR and DDR2 external memory interfaces and multiple external memory options (NOR, NAND, SDRAM).
• High‑speed Storage and I/O — Integrated SATA 3 Gbps controller and USB interfaces (USB 2.0 OTG with integrated PHY and USB 1.1 OHCI with PHY) for storage and peripheral connectivity.
• Networking and Display — 10/100 Mbps Ethernet MAC and an LCD controller for networked and HMI applications.
• Rich Serial Peripherals — Multiple serial interfaces including I2C, SPI, McASP, McBSP, three 16550‑type UARTs, MMC/SD with SDIO and a host-port interface (HPI) for high‑bandwidth external peripherals.
• DMA and Timers — Enhanced DMA controller with multiple channels and configurable transfer burst sizes, plus multiple general‑purpose timers for real‑time scheduling and data movement.
• Power Management — Standard power‑management mechanisms including clock gating and a single PSC clock‑gating domain to help manage subsystem power.
• Package and Temperature — 361‑lead NFBGA package (16×16), surface mount; industrial operating temperature range from −40 °C to 105 °C.
• Compliance — RoHS compliant.

Typical Applications

• Industrial Control — Real‑time PRU cores, multiple timers and industrial temperature rating make the AM1808BZWTA3 suitable for PLCs, motion control and factory automation controllers.
• Human‑Machine Interfaces (HMI) — Integrated LCD controller and serial/parallel peripheral support enable compact HMI designs with local display and input handling.
• Networking Appliances — 10/100 Ethernet MAC combined with USB and multiple serial ports supports edge routers, gateways and protocol converters.
• Embedded Storage and Media — SATA 3 Gbps, USB 2.0 OTG and MMC/SD interfaces provide the connectivity required for NAS clients, media players and local data loggers.

Unique Advantages

• Highly integrated peripheral set — On‑chip SATA, USB, Ethernet, LCD and multiple serial interfaces reduce external components and simplify BOM and board routing.
• Deterministic real‑time capability — The PRU subsystem enables tightly timed I/O and offloaded control tasks without impacting the main ARM core.
• Flexible memory support — Support for LPDDR and DDR2 and multiple external memory interfaces enables scalable system memory configurations.
• Industrial readiness — Surface‑mount 361‑NFBGA package and −40 °C to 105 °C operating range support deployment in industrial environments.
• System power controls — Clock gating and a single PSC clock‑gating domain provide a controllable mechanism for reducing system power in embedded deployments.
• Standards‑based interfaces — IEEE‑compliant Ethernet MAC, USB OTG and host/client support simplify integration with standard peripherals and networks.
