All three devices maintain software compatibility with their predecessor, the
STn8800, according to STM. The STn8810 succeeds the STn8800 with improved video and audio performance, advanced power management features, and a comprehensive security framework to protect sensitive data. On top of these enhancements, the STn8811 and STn8812 provide greater amounts of on-chip SDRAM and NAND Flash.

The STn8810 is based on a 264- to 350-MHz ARM926EJ processor with smart video and audio accelerators, and an advanced power management unit. These features combine to encode or decode 30 frame/second VGA-resolution MPEG-4, H.263, and H.264 video, as well as 5-Mpixel JPEG images and 24-bit audio with noise reduction, echo canceling, stereo enhancements, and surround effects, according to the company. Other multimedia features of the STn8810 include built-in 3D software and a comprehensive audio library.
STMicro says that the STn8810's security framework includes SHA-1 and DES/3DES hardware accelerators, antitamper protection, secure boot loader, a true random-number generator, secured watchdog timer, and unique die identification.
The devices support a wide array of peripheral interfaces including simultaneous TV and color LCD outputs and a camera input, a high-speed (12-Mb/s) USB On-The-Go (OTG) port and a MultiMediaCard, SD Card, and SDIO controller.
The STn8810 is priced at $15 in quantities of 10,000. Samples are available now, with production quantities expected in Q3 2005, according to the company.
