W53322/W53342
60" Voice/Melody/LCD Controller
(ViewTalk
TM
Series)
GENERAL DESCRIPTION
The W53322/W53342 are high-performance 4-bit microcontrollers (碌C) with built-in speech, melody
and 32*48/32*64 LCD driver which includes internal pump circuit. The 4-bit uc core contains dual clock
source, 4-bit ALU, two 8-bit timers, one divider, 20 pin input or output, 7 interrupt sources , 8-level
subroutine nesting for interrupt applications. Speech unit can be implemented with Winbond 60 sec
Power Speech using ADPCM algorithm. Melody unit provides dual tone output and can store up to 1k
notes. Power reduction mode is also built in to minimize power dissipation. It is ideal for games,
educational toys, remote controllers, watches, clocks and other application鈥?products which
incorporate both LCD display and melody.
