Key Features

• Core  ARM926EJ-S 32‑bit processor core, single core operation at up to 454 MHz.
• On-chip Memory  Includes 128‑Kbyte on‑chip SRAM to minimize external RAM requirements for small-footprint RTOS designs.
• Power Management  Integrated PMU with a triple‑output DC‑DC switching converter and multiple linear regulators for device and I/O power sequencing; includes battery charging capability for Li‑Ion batteries as documented in the device datasheet.
• External Memory Support  Supports connections to mobile DDR, DDR2, LV‑DDR2 and SLC/MLC NAND Flash as described in the datasheet.
• Security  Boot security, cryptography and a unique hardware ID are available to support device authentication and secure boot flows.
• Connectivity  Integrated 10/100 Mbps Ethernet and USB 2.0 with integrated PHY for system and peripheral connectivity.
• Co-processor  Includes a data co‑processor (DCP) for offloading certain data operations.
• Package & Mounting  289‑MAPBGA package, 14 × 14 mm, 0.8 mm pitch; surface‑mount device supplied in tray format.
• Graphics  No graphics acceleration (documented as "No" for graphics acceleration).

Typical Applications

• Human‑Machine Interfaces (HMI): Industrial and home HMI panels and graphical remote controls where a compact, low‑power processor with integrated power sequencing is required.
• Industrial Control & Automation: PLCs, I/O control displays and factory robotics displays that benefit from deterministic embedded processing and onboard power management.
• Handheld Devices: Scanners and portable printers that require USB connectivity, compact packaging and reduced external memory needs.
