The W538T808, a member of the ViewTalk family, is an 8-bit Microprocessor (uP) based on a W65C02S core with a speech and melody synthesizer and 64 seg x 32 com LCD Driver unit, which includes an internal Regulator pump circuit and two pages of dedicated LCD RAM. The W538T808 CAN synthesize 8 channels of melody or speech (up to 2 of these channels CAN be speech; the rest are melody) and drive an LCD Display simultaneously. The W538T8xx accepts midi scores in MIDI format 0, and it has multiple power modes to minimize power dissipation, based on different speech, melody, and LCD needs. The Serial-memory Interface Manager (SIM) is designated for cartridge applications. Using the SIM, the W538T8xx can access Winbond proprietary, serial-memory chips W55Fxx and W551Cxxx. It is also ideal for games, remote controllers, watches, Clocks and other applications that incorporate both LCD Display and speech or midi.
