Intel has developed three new processors for personal digital assistants (PDAs) that incorporate the latest microprocessor packaging and stacking techniques. They deliver higher performance and longer battery life in less space than its previous versions.
PDA capabilities have increased significantly over the last year to include integrated Wi-Fi (802.11) high-speed wireless Internet access, colour screens, integrated cameras, and more. This has resulted in the need for greater processing and memory capabilities, all delivered by smaller chips.
The announcement includes two additions to the smaller, Intel PXA26x family, including the Intel PXA263 processor, Intel's first stacked processor for PDAs and the Intel PXA260 processor, a 'pin compatible' product that makes upgrading a PDA design easy and cost-effective for OEMs. The third product, the Intel PXA255 processor, is a replacement to the popular Intel PXA250 processor that extends the overall system performance and battery-life of PDAs.
The PXA260 processor (available in 200, 300, 400 MHz versions) is a standalone device nearly 53% smaller (13 X 13 X 1,4 mm) than prior standalone processors (17 X 17 X 1,75 mm). It is 'pin-compatible' with Intel's PXA26x processor family, enabling the designer to build a single board that can easily stack flash memory and computing products without changing the design.
The Intel PXA263 'stacked' processor brings memory and processor chips together for powerful computing and memory capabilities in a smaller, single system package. The PXA263 processor (also in 200, 300, 400 MHz versions) stacks 32 MB of 32-bit Intel StrataFlash memory with an Intel XScale technology based processor for up to 72% space savings over standalone products.
Stacking advanced computing and memory capabilities in a 'system-in-a-package' design reduces the number of components in a PDA and enables manufacturers to create new and different capabilities and functionality, including a better ability to execute performance-intensive applications such as MPEG4 video decode, speech and handwriting recognition, and games.
The Intel PXA255 processor, compared to its predecessor, the PXA250, has doubled the internal system bus speed a lower voltage technology (1,3 V at 400 MHz). This results in more than 30% lower power consumption in run mode and more than 60% lower in idle mode.
