8. MICROCONTROLLER – MSTAR(U157)

8.1.General Description

The MSD9WB7PX-2 integrates DTV/multi-media all-purpose AV decoder, DVB-T demodulator, VIF
demodulator, and Sound/Video processor into a single device. This allows the overall BOM to be reduced
significantly making the MSD9WB7PX-2 a very competitive multi-media DTV solution. For ATV users, the
MSD9WB7PX-2 provides multi-standard analog TV support with adaptive 3D video decoding and VBI data
extraction. The build-in audio decoder is capable of decoding FM, AM, NICAM, A2, BTSC and EIA-J sound
standards. The MSD9WB7PX-2 supplies all the necessary A/V inputs and outputs to complete a receiver
design including a multi-port HDMI receiver and component video ADC. All input selection multiplexed for
video and audio are integrated, including full SCART support with CVBS output. The equipped MStar
MACE-5 color engine is the latest masterpiece from MStar famous color engine series providing excellent
video and picture quality in Full-HD and large-scale displaying system. To meet the increasingly popular
energy legislative requirements without the use of additional hardware, the MSD9WB7PX-2 has an ultra low
power standby mode during which an embedded MCU can act upon standby events and wake up the
system as required.
