Applied Data Systems (ADS) is shipping a small SBC (single-board computer) based on a high-integration ARM9-based system-on-chip (SoC) processor. The 4-inch-square “Sphere,” which previewed in March, supports Linux and is targeted at handhelds,… gaming gadgets, thin clients, and test/measurement equipment, according to ADS.

The Sphere is based on a Cirrus EP9315 “Universal Platform System-on-chip Processor,” which includes a 32-bit, 200 MHz ARM9 processor, a “MaverickCrunch” Math Engine, a raster/LCD controller with 1024 x 768 resolution at up to 24 bits per pixel, and a 4, 5, 7, or 8 wire analog resistive touchscreen interface.

Additional features implemented by the Sphere SBC — mostly based on the EP9315's extensive on-chip functions — include:

• 10/100 Ethernet
• 3 USB Hosts
• 3 serial ports
  • COM1 — 8-wire, RS232/TTL/debug
  • COM2 — 4-wire, RS232/TTL/IrDA (jumper)
  • COM3 — TTL/RS485 (stuffing option)
• SPI, I2C
• AC 97 audio codec with on-board 2.2 W amplifier
• 2 EIDE
• PCMCIA
• 8×8 keypad scanner

The board supports up to 64 MB of on-board SDRAM, shared between program space and frame buffer, plus 64 MB of Flash memory. A CompactFlash slot is included, for further system expansion.

ADS says the Sphere's low power consumption makes it suitable for enclosed and mobile applications. The board is supplied with a choice of Linux or Windows CE, along with low-level software, hardware, and device interfaces.

Pricing was not disclosed.
