and 32*48/32*64 LCD driver which includes internal pump circuit. The 4-bit uc core contains dual clock
source, 4-bit ALU, two 8-bit timers, one divider, 20 pin input or output, 7 interrupt sources , 8-level
subroutine nesting for interrupt applications. Speech unit can be implemented with Winbond 60 sec
Power Speech using ADPCM 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 melody.

PIN DESCRIPTION

SYMBOL

I/O

FUNCTION

XIN

Input pin for oscillator. It can be connected to crystal, or can connect a
resistor to VDD to generate main system clock. Oscillator can be
stopped when SCR.1 is set to logic 1.

XOUT

Output pin for oscillator which is connected to another crystal pin.

X32I

32.768 KHz crystal input pin.

X32O

32.768 KHz crystal output pin.

RA0 ~ RA3

I/O

General Input/Output port specified by PM1 register. If output mode is
selected, PM0 register can be used to specify CMOS/NMOS driving
capability option. Initial state is input mode.

RB0 ~ RB3

I/O

General Input/Output port specified by PM2 register. If output mode is
selected, PM0 register can be used to specify CMOS/NMOS driving
capability option. Initial state is input mode.

RC0 ~ RC3

4-bit schmitt input with internal pull high option specified by PM0
register. RC0 can be used as clock source for Timer 1. Each pin has
an independent interrupt capability specified by PEFL special register.

RD0 ~ RD3

4-bit schmitt input port with internal pull high option specified by PM0
register. Each pin has an independent interrupt capability specified by
PEFH special register.

triple pump option is enabled. Otherwise, VDD2 connects to VDD
directly if double pump option is enabled.

VDD3

O/I

An output if internal pump circuit is enabled. It connects a 1uF
capacitor to VSS. Triple VDD voltage will be output if triple pump option
is enabled. Otherwise, double VDD voltage will be output if double
pump option is enabled.
