Description
This is a demonstration board based on the STFPC320 which consists of the front panel controller STFPC320 and microcontroller ST72F325 as I2C master. The basic idea is to develop a front panel for a DVD recorder which is very close to the available solutions in the market. The objective of this demonstration board is to display the capabilities of ST's front panel controller/driver STFPC320 to fit the market segment for front panels of DVD players, DVD recorders, VCRs, home theater systems with clock feature, HTiB (home theater in a box), personal video recorders (PVRs), set-top boxes and other applications that require a compact, integrated solution, while keeping system cost as low as possible. The design focus of this system is on 2 key areas: a standby management feature for low power consumption and an embedded real-
