W536020K

The W536020K, a member of ViewTalkTM family, is a high-performance 4-bit micro-controller (uC) with built-in speech unit, melody unit and 40seg * 8 com LCD driver unit which includes internal regulator, pump circuit and dedicated one page LCD RAM. The 4-bit uC core contains dual clock source, 4-bit ALU, two 8-bit timers, one 14 bits divider, maximum 24 pads for input or output, 8 interrupt sources and 8-level nesting for subroutine/interrupt applications. Speech unit, integrated as a single chip with maximum 128 seconds (based on 6.4K sample rate with 5 bits MDPCM) , W536020K is capable of expanding to 512 seconds speech addressed by external memory W536020K with serial bus interface. W536020K can be implemented with Winbond Power Speech using MDPCM 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. W536020K is ideal for games, educational toys, remote controllers, watches, clocks and other application products which incorporate both LCD display and speech.
