GENERAL DESCRIPTION

The W536XXXA, a member of ViewTalk

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.

PAD DESCRIPTION

SYMBOL I/O

FUNCTION

XIN/RXIN

Input pad for main clock oscillator. It can be connected to crystal when crystal
mode is selected (SCR0.2=1), otherwise connect a resistor to VDD to generate
main system clock while RC mode is selected (SCR0.2=0 and default). Oscillator
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

XOUT

Output pad for oscillator which is connected to another crystal pad when in crystal
mode. External capacitor connects to start oscillation when in crystal mode.
