Elf 3 Ultra Low Power XScale Solution

(Utilizing Intel's PXA255)

Elf3 packs complete functionality on 12 inches square and is designed for OEM developers of handheld devices who need the ultimate in peripheral connectivity. With numerous expansion options, Elf3 is based on Intel's PXA255 processor and provides for extended display support, onboard Bluetooth and GPS and memory expansion of up to 32MB Flash and 64MB SDRAM.

CPU - Intel XScale PXA255, up to 400MHz
Flash Memory - 16-32 MB, Intel StrataFlash with bootloader and on-board programming
SDRAM - 32-64 MB with self-refresh and backup (JTAG)

Elf3 provides up to two PCMCIA slots for wireless networking, mass storage, data acquisition or other peripherals. Additional features include ultra-low power consumption by utilizing the advanced power management features of the PXA255 processor, onboard power supply, onboard battery-charging circuitry, and the Elfbus, a custom peripheral connector.

Custom hardware requirements frequently arise in many industrial, biomedical and other data acquisition and signal processing applications. The Elf3 incorporates the Elfbus daughtercard interface on a 50-pin connector. The Elfbus is a 16-bit data bus primarily designed to interface peripherals to the PXA255 system bus. In addition to the address and data signals, the Elfbus provides direct access to processor interrupts, UART and SPI interfaces and a number of generic GPIO signals. ELFbus also provides access to the battery and 5VDC and 3.3VDC power supplies. The LCD display adapter connector allows easy production-quality interfacing to most existing colour and monochrome displays. The adapter also supports an optional touch screen interface. USB device, 14-bit codec and 10 interrupt-capable GPIO pins are also available via Elf3 connectors.

The Elf3 has been designed to give OEMs the choice of tightly wrapping packaging around the onboard peripherals or cabling to off-board peripherals for packaging in a variety of commercially available enclosures. InHand offers full 3D models and IGES files of Elf3 to aid developers in creating their packaging. Engineering Services are also available for custom projects or packaging needs.

The Elf3 development platform provides the starting point for all PXA255 based designs. It comes complete with the hardware, software, and documentation developers need to get started.
