EM73MA89B
4-BIT MICRO-CONTROLLER FOR LCD PRODUCT
Preliminary
10.15.2002 (V1.3)
GENERAL DESCRIPTION
EM73MA89B is an advanced single chip CMOS 4-bit multi-time-programmable (MTP) micro-controller. It
contains 16K-byte ROM, 1012-nibble RAM, 4-bit ALU, 13-level subroutine nesting, 22-stage time base, two 12-
bit timer/counters for the kernel function, and one high speed conter. EM73MA89B also equipped with 6 interrupt
sources, 3~7 I/O ports (including 1 input port and 2~7 bidirection ports), LCD display (64x16 or 64x32), built-in
watch-dog-timer and speech synthesizer.
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
: 2.2V to 3.6V.
Clock source
: Dual clock system. Low-frequency oscillator is 32KHz. Crystal oscillator or RC
oscillator by mask option and high-frequency oscillator is a built-in internal
oscillator.
Instruction set
: 107 powerful instructions.
Instruction cycle time
: 0.85s for 9.2M or 1.7s for 4.6M Hz selected by mask option(high speed clock).
122s for 32768 Hz (low speed clock, frequency double).
ROM capacity
: 16K x 8 bits.
RAM capacity
: 1012 x 4 bits.
Input port
: 1 port (P0.0-P0.3), IDLE/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
: 2~7 ports (P1, P2, P4, P5, P6, P7, P8). IDLE/STOP release function for P8(0..
3) is available by mask option. P1, P2, P5, P6, P7 are shared with LCD pins.
Built-in watch-dog-timer counter : It 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.
Subroutine nesting
: Up to 13 levels.
Interrupt
: External interrupt . . . . . . 2 input interrupt sources.
Internal interrupt . . . . . . 2 timer overflow interrupts, 1 time base interrupt.
1 speech/HTC interrupt.
High speed counter
: The high speed counter includes one 8-bit high speed counter and a resistor to
frequency oscillator. It has resistor to frequrncy oscillation mode, melody mode
and auto load timer mode.
LCD driver
: 64x32 or 64x16 dots, 1/32 or 1/16 duty, 1/5 bias by mask option.
Speech synthesizer
: 992K speech data ROM (use as 992K nibbles data ROM).
PWM or current D/A
: Output selection by mask option.
Power saving function
: SLOW, IDLE, STOP operation modes.
Package type
: Chip form 128 pins.
