PCI Mobile Multimedia Companion Chip

The  SM502  is  a  Mobile  Multimedia  Companion  Chip (MMCC™) device packaged in a 297-pin Ball Grid Array  and is backward-compatible with the SM501. Designed to comply with needs of the embedded sector, the SM502 has video and 2D capabilities. To decrease system costs, the SM502 supports a diverse array of I/Os, including analog RGB and digital LCD Panel interfaces, an 8-bit parallel  interface,  USB,  UART,  IrDA,  two  Zoom  Video (ZV) interfaces, AC97 or I-S, SSP, PWM, and I-C. The additional GPIO bits that can be utilized to interface with external devices.

The 2D engine has front-end colour space conversion with 4:1 and 1:8 scaling support. The video engine supports two different video outputs (Dual Monitor) at 8, 16, or 32-bit per pixel and a 3-color hardware cursor per video output. The LCD Panel video pipe supports back-end YUV color space conversion with 4:1 and 1:212 scaling. A ZV port is also included as an interface for external circuitry for MPEG decoding or TV input.
