STMP3738 System-on-Chip

Introduction

Freescale’s STMP3738 System-on-Chip (SoC) provides customers the ability to design and develop high performance Personal Navigation Devices (PND) for the GPS market. The 90nm STMP3738 SoC is based on the ARM926EJ-S™ core coupled with on-chip audio and power management functions. This highly-integrated SoC eliminates over 10 previously-discreet ICs typically found in PND devices. First used in PMP and MP3 players, the STMP3700 SoC is already introduced into the market and in high volume production. Unlike other ICs based on an ARM9™ core, the Freescale chip integrates the analog functions on the same silicon die as the processor.

Now, the power management functions, normally priced at several dollars and spread across several analog ICs, are integrated at a cost and space savings. Furthermore, the analog audio codec which powers the headphones and speakers is also integrated. Freescale’s SigmaTel product line has a reputation in the MP3 space for its high quality audio performance and this integrated audio codec is no exception. Now, PNDs can offer the same high quality sound previously found only on dedicated MP3 players. Additionally, the 350MHz STMP3738 SoC has video acceleration hardware which allows full QVGA H.264 video playback at 30 frames per second. Not only can you listen to music, but you can also watch full quality, high-resolution video on your PND. The STMP3738 SoC supports WinCE5, WinCE6 and Linux® operating systems.
