AM1806BZCE3

The AM1806BZCE3 is a Sitara AM18xx series microprocessor featuring a single ARM926EJ-S 32-bit core running at 375 MHz. It integrates a broad set of memory controllers and peripheral interfaces to address embedded designs that require balanced processing, real-time I/O, and a compact BGA footprint.

Designed for embedded and industrial markets, the device delivers system-level integration—including DDR2/LPDDR support, Ethernet, USB with integrated PHY, and storage interfaces—helping simplify board design and reduce bill-of-materials for communications, control and HMI applications.

Key Features

• Core & Performance  ARM926EJ-S 32-bit RISC core operating at 375 MHz, provided as a single-core MPU for control and application-level processing.
• Memory Subsystem  Integrated memory controllers for DDR2 and LPDDR, with support for 16-bit DDR2 and mDDR configurations noted in the device family documentation.
• Storage & Mass-Storage Interfaces  On-chip SATA 3Gbps interface (1) for direct connection to storage devices and mass-storage applications.
• Connectivity & I/O  10/100 Mbps Ethernet (1), USB 2.0 with integrated PHY (USB0), multiple SPI and I2C interfaces, and MMC/SD/SDIO channels provide extensive peripheral connectivity options.
• Multimedia & Display  Integrated LCD controller and Video Port Interface (VPIF) support video capture and display use cases with multiple data-width options.
• Real-Time Processing & DMA  Programmable Real-Time Unit Subsystem (PRUSS) with two independent PRU cores (4KB instruction RAM and 512 bytes data RAM per core) plus an Enhanced DMA controller (EDMA3) with multiple channels for deterministic I/O and high-throughput data movement.
• Audio & Serial Peripherals  McASP and McBSP multichannel audio serial ports, AC97 interface, and multiple 16550-type UARTs support audio codecs and telecom/media interfaces.
• System Timers & RTC  Multiple general-purpose timers, a configurable watchdog timer, and an RTC with 32-kHz oscillator provide robust timing and supervisory capabilities.
• Package & Environmental  361-NFBGA (13×13) surface-mount package; commercial-grade operating temperature range 0°C to 90°C; RoHS compliant.

Typical Applications

• Industrial Automation  Deterministic I/O and PRU real-time units support motor control, sensor management, and factory-control tasks requiring tight timing and robust peripheral integration.
• Human-Machine Interfaces (HMI)  Integrated LCD controller and multimedia capture interfaces enable local displays and user interfaces for appliances and control panels.
• Networking & Communications  On-chip Ethernet, USB 2.0 with PHY, and storage interfaces make the device suitable for gateway and embedded networking applications.
• Multimedia Data Acquisition  Video Port Interface, McASP/McBSP audio interfaces, and DMA support facilitate multimedia capture and streaming use cases.

Unique Advantages

• Integrated peripheral set: Combines Ethernet, USB with PHY, SATA, LCD and multiple serial interfaces to reduce external component count and simplify system design.
• Real-time capability: PRU subsystem with dedicated instruction and data RAM plus a high-channel EDMA3 controller enables deterministic offload of time-critical tasks.
• Flexible memory options: DDR2 and LPDDR controller support provides design flexibility for a range of memory and cost targets.
• Compact BGA package: 361-NFBGA (13×13) footprint supports high-density board layouts while maintaining accessible I/O.
• Commercial temperature and RoHS compliance: 0°C to 90°C operating range and RoHS status align with commercial embedded deployment requirements.
