AM1808BZCE4

The AM1808BZCE4 is a Sitara AM18xx series microprocessor from Texas Instruments featuring a single ARM926EJ-S 32‑bit core running at 456 MHz. It is a commercial‑grade, surface‑mount MPU in a 361‑pin NFBGA (13×13 mm) package designed for embedded applications that require a balance of processing performance and broad peripheral integration.

With integrated memory controllers, multiple high‑speed and legacy interfaces, and a programmable real‑time subsystem, this device targets embedded designs where system integration, connectivity and deterministic I/O are important.

Key Features

• Core – ARM926EJ‑S 32‑bit RISC processor running at 456 MHz, supporting both 32‑bit and 16‑bit (Thumb) instruction sets.
• Programmable Real‑Time Unit Subsystem (PRUSS) – Two independent PRU cores with on‑chip instruction and data RAM, designed for deterministic real‑time tasks and low‑latency I/O processing.
• Memory – On‑chip 128 KB memory and support for external memory via DDR2, LPDDR and mDDR controllers; external NOR and NAND interfaces supported through EMIFA.
• Caches and On‑Chip ROM – 16 KB instruction cache, 16 KB data cache and 64 KB of on‑chip ROM for boot and system routines.
• Connectivity – Integrated 10/100 Mbps Ethernet MAC, USB 2.0 OTG with PHY and USB 1.1 with PHY, and SATA 3 Gbps controller for wired networking and storage.
• Multimedia and Audio – LCD controller and video port interface (VPIF) plus McASP and McBSP audio interfaces for display and audio subsystem integration.
• Serial and Peripheral Interfaces – Multiple UARTs (16550‑type), SPIs, I2C, MMC/SD (with SDIO) and HPI (16‑bit host port interface) for broad peripheral support.
• DMA and Timers – Enhanced DMA controller (EDMA3) with multiple channels and dedicated interrupt controller; several configurable general‑purpose timers for system timing and control.
• Power and System Management – Standard power‑management features including clock gating and a single PSC clock‑gating domain to reduce power during idle periods.
• Package and Temperature – 361‑pin NFBGA package (13×13 mm), surface mount; commercial operating temperature range 0 °C to 90 °C.

Typical Applications

• Industrial embedded control – Deterministic PRU cores, multiple timers and extensive I/O make the device suitable for machine control, data acquisition and automation tasks.
• Networking and communications – Integrated 10/100 Ethernet MAC, USB OTG and PHYs enable networking gateways, protocol converters and connectivity-focused appliances.
• Multimedia and human‑machine interfaces – LCD controller, VPIF and audio interfaces support user displays and multimedia front‑ends for equipment and kiosks.
• Storage and embedded hosts – SATA 3 Gbps plus MMC/SD interfaces provide options for local storage, removable media and embedded host controllers.

Unique Advantages

• Highly integrated peripheral set: Combines Ethernet, USB (1.1 and 2.0 with PHYs), SATA, LCD and multiple serial interfaces to reduce external component count and simplify BOM.
• Real‑time offload capability: Dual PRU cores with dedicated RAM let designers implement low‑latency control and I/O processing without burdening the main ARM926 core.
• Flexible memory support: On‑chip memory plus controllers for DDR2, LPDDR and mDDR allow scalable memory configurations for a range of application needs.
• Deterministic data movement: Enhanced EDMA3 controller with many channels and quick DMA options streamlines high‑bandwidth transfers and reduces CPU intervention.
• Commercial temperature and compact package: 361‑pin NFBGA (13×13 mm) surface‑mount package with 0 °C to 90 °C operating range fits compact embedded designs.
