Back in May 2004, we reported that Strategic Test Corp. (Cambridge, Mass.) had a new Intel PXA255-based processor board that was much smaller than a credit card. Strategic Test's tiny board housed a 400-MHz PXA255 microprocessor, which is part of Intel's Xscale processor family.
On the heels of that announcement, Strategic Test is now releasing a tiny single-board computer with an Intel PXA270 aboard. The new board measures just 1.2 x 2.6 x 0.16-in. (31 x 67.6 x 4.2-mm) in size. Dubbed the TRITON-270, it's is a DIMM200-compatible module optimized for mobile embedded designs where low-power and extremely small size are design factors.
Significantly, Strategic Test is also releasing a development kit that lets the TRITON-270 run out-of-the-box with Linux kernel 2.6, or Windows CE 5.0 operating systems pre-installed. TRITON modules are also supplied with the RedBoot operating system boot loader. It's also pre-installed.
For its part, the PXA270 is the first Intel XScale processor to include so-called Intel Wireless MMX. It enables multi-media acceleration based on the Pentium instruction set.
The PXA270 also imparts Intel's Quick Capture. It's a camera interface for capturing digital images and video. Finally, the PXA270 also includes the new Wireless Intel SpeedStep Technology for very low-power operation.
A standard TRITON-270 module is supplied with a 512-MHz PXA270 microprocessor, 64 Mbytes of 1.8-V low-power mobile SDRAM, and 16 Mbytes of 1.8-V flash. The block diagram will give you insight as to how much is packed into this ultra-small product.

Note that Strategic Test also offers options for 312-MHz and 416-MHz processors, as well as trimmed-down memory options offering 32 Mbytes of SDRAM and eight Mbytes of flash.
It's Power Managed
In addition to standard PXA270 chip power-management capabilities, Strategic Test also includes a programmable core voltage generator on the TRITON module. This lets you vary the PXA270 supply voltage from 1.1-V to 1.3-V to further reduce dissipation.
In terms of I/O, the TRITON-270 uses a 200-pin DIMM connector to bring out all of the PXA270's internal signals. These include an integrated LCD controller for direct connection to a display, a PCMCIA interface, a Bluetooth UART, and a baseband/multimedia interface, a Universal Serial Bus 2.0 On-the-Go serial interface.
The TRITON-270 also packs a built-in memory stick controller, an MMC/SD/SDIC interface, an I2S port, AC'97 audio interfaces, three SSP and three asynchronous serial interfaces. Rounding that out, the module also includes a keypad interface, GPIO (general purpose I/O), and four PWM interfaces.
Strategic Test says its TRITON-270 is available immediately priced at a bit less than $300 a pop in quantities of 1,000. Configurations with less SDRAM and flash, or for extended operating temperature ranges, are available with minimum order quantities of 100 pieces.
