• Caches and MMU 8-Kbyte data cache, 16-Kbyte instruction cache and write buffer, plus a Memory Management Unit for virtual memory support and system performance.
• On‑chip Flash Controller Enhanced Embedded Flash Controller (EEFC) with 128-bit wide access to speed flash operations and improve performance in ARM and Thumb modes.
• High‑speed Connectivity USB 2.0 full-speed device support and, in the 217-ball LFBGA device, dual USB host ports with integrated transceivers and configurable FIFOs/DMA channels; on-chip 2,688-byte configurable DPRAM for USB buffering.
• Ethernet Integrated 10/100 Base-T Ethernet MAC with MII or RMII interface, 128-byte FIFOs and dedicated DMA channels for efficient packet handling.
• Image Sensor Interface ITU-R BT.601/656 external interface with 12-bit data support, programmable frame capture rate, preview path with scaler and YCbCr format support for camera front-ends.
• External Bus & Storage External Bus Interface (EBI) supporting SDRAM, static memory, ECC-enabled NAND Flash and CompactFlash devices for flexible external memory expansion.
• System & Debug EmbeddedICE debug support, Debug Communication Channel, Reset and Power Management Controllers, Advanced Interrupt Controller, watchdog and real-time timers.
• Package & Temperature 217-LFBGA (15×15) surface-mount package rated for industrial operation from −40 °C to 85 °C.

Typical Applications

• Industrial Control — Embedded controllers and automation nodes leveraging the ARM926EJ-S core, industrial temperature range and extensive peripheral set for networking and I/O.
• Human‑Machine Interfaces (HMI) — LCD and touchscreen controller support plus integrated memory and USB/Ethernet connectivity for interactive operator panels and display systems.
• Imaging & Vision Modules — Image Sensor Interface with preview and scaler capabilities for camera capture, processing and streaming applications.
• Connectivity Gateways — Built-in Ethernet MAC and USB host/device ports enable compact networked gateways, protocol converters and data acquisition controllers.

Unique Advantages

• Integrated Memory Subsystem — On-chip flash, ROM and SRAM reduce external component count and simplify board layout for compact designs.
• High Integration of Peripherals — USB host/device, Ethernet MAC, image interface and flexible EBI reduce the need for external controllers and accelerate time-to-market.
• Performance for Embedded Tasks — 180 MHz ARM926EJ-S core with caches and MMU delivers up to 200 MIPS for control, networking and media handling workloads.
• Industrial Temperature Rating — −40 °C to 85 °C operating range supports deployment in demanding environments.
• Flash Management & Reliability — Enhanced Embedded Flash Controller and documented flash program/erase performance plus endurance and data-retention characteristics aid product reliability planning.
• Compact, Surface‑Mount Package — 217-LFBGA (15×15) footprint provides a high-density solution for space-constrained embedded platforms.
