AM1808BZWTD4

The AM1808BZWTD4 is a Sitara AM18xx family microprocessor IC based on a single ARM926EJ-S core running at 456 MHz. It is designed for industrial embedded applications that require a balance of processing performance, integrated peripheral interfaces and wide operating temperature range.

With on-chip memory, programmable real-time units (PRUSS), and a broad set of I/O including Ethernet, USB, SATA and display controllers, the AM1808BZWTD4 targets industrial control, HMI and networked embedded designs that benefit from high integration and robust platform support.

Key Features

• Core and Performance — ARM926EJ-S single 32‑bit core at 456 MHz providing deterministic RISC processing for embedded workloads.
• Real-Time Subsystem — Programmable Real-Time Unit Subsystem (PRUSS) with independent PRU cores, useful for time-critical I/O and offloading tasks from the main core.
• Memory and On-Chip Storage — 128 KB of on-chip memory, with support for external memory controllers for LPDDR and DDR2; includes instruction and data caches to improve performance.
• High-Speed Interfaces — Integrated USB 2.0 OTG with PHY and USB 1.1 host with PHY, plus SATA 3 Gbps and 10/100 Mbps Ethernet MAC for storage and network connectivity.
• Multimedia and Display — LCD controller and Video Port Interface (VPIF) for display and video capture/processing use cases; audio interfaces include McASP and multichannel serial ports.
• Peripheral and Expansion — Multiple UARTs (16550-type), SPI, I2C, MMC/SD/SDIO, McBSP, GPIO and a host-port interface (HPI) for high-bandwidth external connections.
• DMA and Timers — Enhanced DMA (EDMA3) with multiple channels and configurable transfer bursts, plus general-purpose timers for deterministic timing and event management.
• Package and Mounting — 361-ball NFBGA supplier package (16×16) in a surface-mount form factor suitable for compact embedded PCBs.
• Industrial Grade and Temperature Range — Industrial grade device with operating temperature range of −40 °C to 90 °C, suited for harsh environments.
• Compliance — RoHS compliant.

Typical Applications

• Industrial Automation — Real-time control and sensor interfacing using the ARM926EJ-S core combined with PRU offload and robust I/O sets for deterministic system control.
• Human-Machine Interfaces (HMI) — LCD controller and multimedia interfaces enable touchscreen displays and local user interface processing for industrial panels and kiosks.
• Networked Embedded Systems — Integrated 10/100 Mbps Ethernet MAC, USB and SATA provide connectivity and storage options for gateways, controllers and edge devices.
• Multimedia and Audio Processing — McASP, McBSP and VPIF support audio codecs and video I/O for embedded multimedia applications and signage.

Unique Advantages

• Integrated Peripheral Set: Extensive on-chip interfaces (Ethernet, USB, SATA, display and audio ports) reduce external component count and simplify BOM.
• Real-Time Offload Capability: Programmable Real-Time Unit Subsystem (PRUSS) enables deterministic handling of timing-critical tasks without burdening the main CPU.
• Flexible Memory Support: On-chip memory plus LPDDR/DDR2 controller support allows designers to scale external memory as application needs grow.
• Industrial Reliability: Specified for −40 °C to 90 °C operation and supplied in a compact BGA package suitable for industrial embedded deployments.
• Comprehensive I/O for Embedded Systems: Rich mix of serial, parallel and multimedia interfaces eases integration into diverse embedded product designs.
