AM1806BZWT4

The AM1806BZWT4 is a Sitara™ ARM926EJ-S microprocessor from Texas Instruments, delivering a single 32-bit core running at 456 MHz. It is designed for embedded applications that require a balance of processing performance and integrated peripheral interfaces.

Built on the Sitara AM18xx family architecture, this device integrates memory controllers, high-speed peripheral interfaces and real-time subsystem features to support communication, multimedia I/O and control-oriented designs.

Key Features

• Core ARM926EJ-S 32-bit RISC processor running at 456 MHz in a single-core configuration, providing predictable 32-bit processing for embedded workloads.
• Memory Interfaces Supports LPDDR and DDR2 memory controllers. Datasheet details include 16-bit DDR2 and mDDR controllers with up to 256-MB address spaces and 16-bit SDRAM support with 128-MB address space.
• Peripheral and Display Integrated LCD controller and Video Port Interface (VPIF) for raw capture and display channels (8-, 10-, 12-, and 16-bit options noted in documentation).
• Storage and Connectivity On-chip 10/100 Mbps Ethernet (1), SATA 3 Gbps (1) and USB 2.0 with integrated PHY supporting OTG, host and client modes, enabling networked and storage-capable embedded devices.
• Serial and Control Interfaces Includes I2C, multiple UARTs (three 16550-type), two SPIs, two MMC/SD interfaces with SDIO support, McBSP/McASP audio serial ports and a uPP high-speed parallel interface.
• Real-Time and DMA Programmable Real-Time Unit Subsystem (PRUSS) with two independent PRU cores (4 KB instruction RAM and 512 bytes data RAM per core) plus an Enhanced DMA controller (EDMA3) with up to 64 channels for deterministic I/O and high-throughput data movement.
• Timers and RTC Multiple general-purpose timers and a real-time clock with a 32-kHz oscillator are included for system timing, watchdog and scheduling functions.
• Power-Management Features Standard power-management mechanisms and clock-gating domains allow subsystem-level clock control for power optimization.
• Package and Temperature Supplied in a 361-NFBGA (16×16) surface-mount package, rated for commercial operation from 0 °C to 90 °C.

Typical Applications

• Embedded Control Systems — Deterministic PRU cores, extensive serial interfaces and EDMA support sensor interfacing, real-time control and industrial I/O tasks.
• Human-Machine Interfaces (HMI) — Integrated LCD controller and multimedia capture/display interfaces support device front-ends and operator displays.
• Networked and Storage Appliances — On-chip Ethernet, SATA 3 Gbps and USB 2.0 PHY enable network gateways, storage controllers and connected peripherals.
• Audio and Multimedia Modules — McASP and McBSP ports plus VPIF and audio codec interfaces accommodate multichannel audio and multimedia data streams.

Unique Advantages

• Highly integrated peripheral set: Ethernet, SATA, USB 2.0 with PHY, LCD and multiple serial buses reduce external components and simplify system design.
• Flexible memory support: LPDDR, DDR2 and mDDR controller options with documented address spaces let designers choose memory configurations that match capacity and performance needs.
• Deterministic I/O with PRU subsystem: Two programmable real-time cores with dedicated instruction and data RAM enable low-latency, real-time processing alongside the main ARM core.
• Advanced DMA and timing: EDMA3 with many channels and multiple general-purpose timers offloads data movement and timing tasks from the CPU to improve throughput and responsiveness.
• Power-management capabilities: Clock gating and standard power-management mechanisms provide control over subsystem power states for optimized energy use.
• Commercial temperature and compact package: 361-NFBGA (16×16) surface-mount package with 0 °C to 90 °C operating range fits space-constrained embedded designs.
