GENERAL DESCRIPTION
EM73C63 is an advanced single chip CMOS 4-bit micro-controller. It contains 32K-byte ROM, 500-nibble
RAM, 4-bit ALU, 13-level subroutine nesting, 22-stage time base, two 12-bit timer/counters for the kernel
function. EM73C63 is also equipped with 5 interrupt sources, 3 I/O ports (including 1 input port and 2 bidirection
ports),LCDdisplay(40x16),built-insoundgenerator.
It's low power consumption and high speed feature are further strengten with DUAL, SLOW, IDLE and STOP
operation mode for optimized power saving.
FEATURES
• Operation voltage
• Clock source
: 2.4V to 5.5V.
: Dual clock system. Low-frequency oscillator is Crystal or RC oscillator (32KHz,
connect a external resistor) by mask option and high-frequency oscillator is RC
oscillator (connect a external resistor and a capacitor).
External clock and internal clock is available by mask option.
Oscillation frequency : 480K, 1M, 2M and 4M Hz are both available for high frequency clock by mask option.
Instruction set
: 107 powerful instructions.
Instruction cycle time : Up to 2 µs for 4 MHz (high speed clock).
244 µs for 32768 Hz (low speed clock).
ROMcapacity
: 32768 X 8 bits.
RAMcapacity
: 500 X 4 bits.
Input port
: 1 port (P0.0-P0.3), IDEL/STOP releasing function is available by mask option.(each
input pin has a pull-up and pull-down resistor available by mask option).
Bidirection port
: 2 ports (P4, P8). P4.0 and SOUND are available by mask option. IDEL/STOP
releasing function for P8(0..3) is available by mask option.
12-bit timer/counter : Two 12-bit timer/counters are programmable for timer, event counter and pulse width
measurement mode.
Built-in time base counter : 22 stages.
Subroutinenesting
: Up to 13 levels.

1 Time base interrupt.
LCD driver
: 40 X 16 dots, 1/16 duty, 1/5 bias with voltage multiplier.
Sound effect
: Tone generator, random generator and volume control.
Power saving function: SLOW, IDLE, STOP operation modes.
Package type
: Chip form 84 pins, PLCC 84 pins.
