SM107

Overview
The SM107 is a Mobile Multimedia Companion Chip
(MMCC™) device packaged in a 208-pin Ball Grid Array
(BGA). Designed to meet the needs of the embedded
industry, SM107 provides video and 2D capabilities. To
decrease system costs, the SM107 supports a wide variety
of I/Os, including analog RGB and digital LCD Panel
interfaces, two Zoom Video (ZV) interfaces, and Pulse
Width Modulation (PWM). There are additional GPIO bits
can be used to interface external devices.

The 2D engine has a 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 three-color hardware cursor per video
output. The LCD panel video pipe supports a back-end
YUV color space conversion with 4:1 and 1:212 scaling.
A ZV port is included as an interface for external circuitry
for MPEG decoding or TV input.
