AM1808EZCE4

The AM1808EZCE4 is a Sitara AM18xx family microprocessor from Texas Instruments featuring a single 32-bit ARM926EJ-S core running at 456 MHz. Designed for embedded applications, the device integrates a rich set of on-chip peripherals and external memory interfaces to support connectivity, storage, real-time control and human-machine interfaces.

With integrated USB, Ethernet, SATA and multiple serial interfaces plus dedicated memory controllers and a programmable real-time unit subsystem, this commercial-grade, surface-mount MPU targets embedded systems that require a balanced combination of processing, I/O integration and deterministic I/O handling.

Key Features

• Core  ARM926EJ-S single core, 32-bit RISC processor operating at 456 MHz for general-purpose embedded processing.
• Memory and Caches  On-chip memory and cache resources include instruction and data caches and on-chip ROM; supports external memory via two external memory interfaces including EMIFA for NOR/NAND and a DDR2/mDDR memory controller.
• Programmable Real-Time Unit Subsystem (PRUSS)  Two independent programmable real-time cores with local instruction/data RAM; PRUSS can be disabled via software to save power and offloads deterministic I/O and timing-critical tasks.
• Storage Interfaces  Integrated SATA 3Gbps host interface for storage connectivity and MMC/SDIO support for removable media.
• USB and Host Support  USB 2.0 with integrated PHY and USB 1.1 host (OHCI) with integrated PHY for peripheral and host connectivity.
• Ethernet  10/100 Mbps Ethernet MAC for networked applications.
• Serial and Peripheral Interfaces  Multiple UARTs (three configurable 16550-type), SPI ports, I2C, audio serial port and additional control interfaces for sensor and peripheral integration.
• Timers and PWMs  Multiple general-purpose timers, capture modules and enhanced PWM units suitable for control and timing functions.
• I/O and Voltage Options  1.8 V or 3.3 V LVCMOS I/Os (except USB and DDR2 interfaces) to support common embedded signaling levels.
• Package and Temperature  361-ball NFBGA supplier package (13 × 13 mm) in a surface-mount form factor; commercial grade with operating temperature 0 °C to 90 °C.
• Standards and Compliance  RoHS compliant.

Typical Applications

• Industrial Control  Use the PRU subsystem and multiple timers for deterministic I/O, motor control and real-time machine interfacing.
• Networking and Communications  10/100 Mbps Ethernet MAC and multiple UART/SPI/I2C ports enable gateway, router and appliance-level networking tasks.
• Embedded Storage and Media  SATA 3Gbps plus MMC/SDIO support make the device suitable for storage controllers and media management in embedded systems.
• Human-Machine Interfaces  Integrated LCD controller and rich peripheral set support user interfaces and local display control.

Unique Advantages

• Highly integrated connectivity: Ethernet, USB 2.0/1.1, SATA and MMC/SDIO on-chip reduce external components and simplify system design.
• Real-time offload with PRUSS: Two programmable real-time cores provide deterministic I/O handling and can be disabled for power savings when not required.
• Flexible memory support: Dual external memory interfaces including EMIFA and DDR2/mDDR controller accommodate a range of NOR/NAND/DRAM configurations.
• Compact surface-mount package: 361-ball NFBGA (13 × 13 mm) delivers high integration density for space-constrained boards.
• Embedded control resources: Multiple UARTs, SPI, I2C, timers and PWMs make it suitable for device control, sensor interfacing and peripheral management.
• Commercial temperature and RoHS compliance: Specified for 0 °C to 90 °C operation and RoHS-compliant manufacturing.
