GENERAL DESCRIPTION
The W536XXXA, a member of ViewTalk
TM
family, is a high-performance 4-bit micro-controller (uC) with
built-in speech unit, melody unit and 64seg * 16 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.

(2) Dedicate serial bus 3 pads (RDP, SPDATA and WRP) to interface with W55XXX. Cascaded
Voice ROM can help 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.

can be enabled or stopped by set SCR0.1 to 1 or clear to 0 separately. External
capacitor connects to start oscillation while crystal mode
