Silicon Motion SM502 - Manual

Vogager Family
SM502
Overview
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 color 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.
