简 介:W53300/W53320 16" Voice/Melody/LCD Controller (ViewTalkTM Series)
GENERAL DESCRIPTION
The W53300/W53320 are a high-performance 4-bit microcontroller (C) with built-in speech, melody and 16*48/32*48 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 and 8-level subroutine nesting for interrupt applications. Speech unit can be implemented with Winbond 16-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 products which incorporate both LCD display and melody.
