STMP3738

SigmaTel Inc. has introduced a highly-integrated SoC processor solution for the portable navigation GPS market that incorporates 12 previously-discrete ICs typically found in personal navigation devices (PNDs). The STMP3738 supports WinCE5, WinCE6 and Linux operating systems. It allows customers to quickly develop and introduce PND products into the market at attractive price points.

"We are excited to be entering a new high growth consumer market that capitalises on our mixed-signal integration and performance capabilities," said Glen Burchers, director of marketing for SigmaTel. "With the STMP3738, PND BOM cost is reduced by 15 per cent and board space by 30 per cent, without sacrificing performance. Furthermore, the STMP3738 is based on the flagship 3700 processor family of which SigmaTel has already shipped millions."

Armed device
The 90nm STMP3700 family uses an ARM9 processor coupled with on-chip audio and power management functions. Unlike other ARM9 based ICs, the SigmaTel device integrates analogue functions on the same silicon die as the processor. In addition, the power management functions, typically spread across several analogue ICs, are also integrated into the STMP3738 resulting in significant overall cost savings.

Available now, the STMP3738 supports popular GPS solutions including: Broadcom, SiRF and NXP. Both Linux and WinCE operating systems ports are available from SigmaTel. All popular map application software and map databases are compatible with the SigmaTel processor.
