1. GENERAL DESCRIPTION
The W536QXXX, a member of ViewTalk
TM
family, is a high-performance 4-bit micro-controller (uC)
with built-in speech unit, melody unit and 40seg * 16 com LCD driver unit which includes internal
regulator pump circuit and dedicated one pages LCD RAM. The 4-bit uC core contains dual clock
source, 4-bit ALU, two 8-bit timers, one 14 bits divider, 12 pads for input or output, 7 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 that incorporate both LCD display and speech.

Notes:
1. Share 3 pads of RD port (RD1/ADDR, RD2/DATA and RD3/CLK)
2. Dedicate serial bus 3 pads (ADDR, DATA and CLK) 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.
