AM1810BZWTA3

The AM1810BZWTA3 from Texas Instruments is an industrial-grade Sitara AM18xx series microprocessor based on a single ARM926EJ-S 32-bit core running at 375 MHz. It combines a high-performance processor core with extensive peripheral integration—suitable for embedded systems requiring real-time control, industrial networking, storage and host/device USB connectivity, and broad memory interface support.

Key Features

• Core & architecture — Single ARM926EJ-S 32-bit core operating at 375 MHz, delivering deterministic RISC processing for embedded workloads.
• Programmable Real-Time Subsystem (PRUSS) — Includes a PRU subsystem (with two PRU cores and PROFIBUS capability) and small dedicated RAMs and caches to support offloaded real-time tasks and deterministic I/O handling.
• On-chip memory and caches — 128 KB on-chip memory plus instruction/data cache and PRU RAM areas documented in the device series for low-latency code and data access.
• Memory controllers — Supports LPDDR and DDR2 memory interfaces and external memory through EMIFA for NOR and NAND devices to enable flexible system memory architectures.
• High-speed storage and host interfaces — Integrated SATA 3 Gbps controller and USB ports (USB 2.0 OTG with PHY and USB 1.1 OHCI host with PHY) for storage and peripheral connectivity.
• Networking — 10/100 Mbps Ethernet MAC (EMAC) with management interface support for embedded networking tasks.
• Multimedia and audio interfaces — Video port interface (VPIF), multimedia serial ports (McASP, McBSP) and an LCD controller for audio/video and display subsystem integration.
• Serial and peripheral buses — Multiple UARTs, two SPI controllers, I2C support, MMC/SD interfaces with SDIO, and MDIO for PHY management to handle a wide range of peripherals and sensors.
• DMA and timing — Enhanced DMA controller (EDMA3) and multiple general-purpose timers for efficient data movement and precise timing control.
• Industrial grade and package — Supplier device package 361-NFBGA (16×16), surface-mount package and industrial operating temperature range of −40°C to 105°C.
• Compliance — RoHS compliant.

Typical Applications

• Industrial communications and fieldbus gateways — PRUSS with PROFIBUS capability and integrated Ethernet make the AM1810BZWTA3 suitable for deterministic industrial network endpoints and protocol conversion.
• Embedded storage and connectivity appliances — On-chip SATA and USB 2.0/1.1 interfaces support compact storage controllers, gateway devices and USB host/device applications.
• Human-machine interfaces (HMI) — LCD controller and VPIF enable display-driven embedded interfaces for operator panels and control displays.
• Audio and multimedia processing — McASP and McBSP audio interfaces support TDM/I2S-style audio paths for industrial audio and media systems.
• Industrial control and data acquisition — ARM926 core with EDMA and multiple serial interfaces suits motor controllers, sensor aggregation, and real-time data acquisition systems.

Unique Advantages

• Highly integrated I/O set: Combines Ethernet, SATA, dual USB PHYs, multiple serial buses and multimedia interfaces to reduce external components and simplify board design.
• Deterministic real-time support: PRUSS with dedicated PRU cores and local RAM enables offloading of time-critical I/O and protocol handling for predictable system behavior.
• Flexible memory options: Native LPDDR and DDR2 controllers plus EMIFA for NOR/NAND provide designers with multiple memory architecture choices to match cost and performance targets.
• Industrial robustness: Specified operating temperature range of −40°C to 105°C and surface-mount 361-NFBGA packaging for deployment in industrial environments.
• Efficient data movement: Enhanced DMA (EDMA3) support and multiple timers streamline high-throughput data paths and offload CPU cycles for application tasks.
• Standards-based connectivity: 10/100 Mbps Ethernet MAC, SD/MMC with SDIO, SPI, I2C and UARTs provide broad compatibility with common peripheral ecosystems.
