AM1808BZWT4

The AM1808BZWT4 is a single-core Sitara AM18xx microprocessor based on the ARM926EJ-S architecture, running at 456 MHz. Designed for embedded systems, it combines a compact 361-NFBGA (16×16) package with a broad peripheral set for connectivity, memory interfacing, and real-time I/O.

Its integration of USB 2.0 OTG, USB 1.1, 10/100 Mbps Ethernet, SATA 3Gbps and DDR2/LPDDR memory controllers makes it suitable for embedded designs that require balanced compute performance and multiple high-speed interfaces.

Key Features

• Core Processor ARM926EJ-S RISC core, single 32-bit core operating at 456 MHz as specified for this part.
• Real-Time Subsystem (PRUSS) Programmable Real-Time Unit Subsystem with two independent PRU cores, embedded instruction and data RAM per core, and the ability to disable PRUSS via software to save power (as documented in the AM1808 series datasheet).
• Memory and External Memory Interfaces On-chip 128 KB memory plus support for external memory via EMIFA and a DDR2/mobile DDR memory controller. The device supports LPDDR and DDR2 memory types and both NOR and NAND external memory interfaces.
• High-Speed Connectivity Integrated USB 2.0 OTG with PHY and USB 1.1 with PHY, one 10/100 Mbps Ethernet MAC, and one SATA 3 Gbps interface provide multiple high-bandwidth peripheral options.
• Peripheral and I/O Interfaces Multiple serial interfaces including I2C, SPI, McASP audio, McBSPs, three 16550-type UARTs, MMC/SD with SDIO, HPI 16-bit host-port interface, and LCD and video port interfaces for display and video I/O (features noted in the AM1808 series documentation).
• DMA, Timers and System Control Enhanced DMA controller (EDMA3) with extensive channel support and a dedicated interrupt controller, plus multiple general-purpose timers, enabling efficient data movement and timing for real-time applications.
• Package and Temperature 361-NFBGA (16×16) surface-mount package; commercial-grade operation from 0 °C to 90 °C.

Typical Applications

• Embedded Networking Devices — Use the integrated 10/100 Mbps Ethernet MAC and USB interfaces for routers, gateways, and networked controllers requiring moderate processing and connectivity.
• Multimedia and Display Control — LCD controller and video port interface (VPIF) support display and video capture/control tasks in user-interface and embedded video systems.
• Storage-Enabled Appliances — SATA 3 Gbps and multiple memory-interface options enable local storage and high-bandwidth data buffering in multimedia and industrial applications.
• Industrial and Real-Time Control — Programmable Real-Time Units (PRUs), EDMA3, and rich serial interfaces provide deterministic I/O and offloaded processing for control, data acquisition, and protocol handling.

Unique Advantages

• Highly integrated connectivity: On-chip USB 2.0 OTG, USB 1.1, Ethernet and SATA reduce external components and simplify board-level design.
• Deterministic real-time capability: PRUSS with dedicated instruction and data RAM per PRU enables low-latency, offloaded real-time processing for protocol handling and control tasks.
• Flexible memory subsystem: Support for LPDDR and DDR2 plus EMIFA for NOR/NAND gives designers options for cost, capacity, and performance trade-offs.
• Efficient data movement: EDMA3 with extensive channel support and dedicated interrupt resources minimizes CPU overhead for high-throughput transfers.
• Compact, production-ready package: 361-NFBGA (16×16) surface-mount package in a commercial temperature grade facilitates compact board designs for embedded products.
