1. GENERAL DESCRIPTION
The W536XXXT, a member of ViewTalk
TM
family, is a high-performance 4-bit micro-controller (uC)
with built-in speech unit, melody unit and 64seg * 32 com LCD driver unit which includes internal
regulator,pump circuit and dedicated two pages 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), is capable
of expanding to 512 seconds speech addressed by external memory W55XXX with serial bus
interface.
It 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. It is ideal for games, educational toys, remote controllers, watches, clocks and other
application products which incorporate both LCD display and speech.

Notes:
(1). Share 3 pads of RD port (RD1/CLK, RD2/DATA and RD3/ADDR)
(2). Dedicate serial bus 3 pads (CLK, DATA and ADDR) to interface with W55XXX. Cascaded Voice ROM can help user to
expand voice up to 512 sec by W55XXX chip.
(3). Tri-state serial bus mask option can float serial bus while voice playing is no active. Let this mask option is disabled to get
minimum power consumption in general.
