W538A8XX Data Sheet
1. GENERAL DESCRIPTION
The W538A8xx, a member of the ViewTalkTM family, is an 8-bit microprocessor (uP) with a speech and
melody synthesizer and 64SEG x 16COM LCD driver unit, which includes an internal regulator, pump
circuit and two pages of dedicated LCD RAM. The W538A8xx 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 W538A8xx 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
W538A8xx 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.
