4-bit micro-controller for lcd product

EM73P362
4-BIT MICRO-CONTROLLER FOR LCD PRODUCT
GENERAL DESCRIPTION
EM73P362 is an advanced single chip CMOS 4-bit one-time-programmable (OTP) micro-controller. It contains
3K-byte ROM, 52-nibble RAM, 4-bit ALU, 13-level subroutine nesting, 22-stage time base, one 12-bit timer for
the kernal function and one high speed counter. EM73P362 also contains 5 interrupt sources, 1 input port, 4
bidirection ports, built-in watch-dog-timer and LCD driver (27x3 to 15x3).
Except low-power consumption and high speed, EM73P362 has the STOP mode and IDLE mode operation for
power saving function.
FEATURES
• Operation voltage
• Clock source
: 1.3V to 1.8V. (clock frequency : 32K Hz)
: Single clock system for crystal, connect a external resistor or external clock
source, available by mask option.
Instruction set
: 109 powerful instructions.
Instruction cycle time
: Up to 122µs for 32 K Hz.
ROM capacity
: 3072 x 8 bits.
RAM capacity
: 52 x 4 bits.
Input port
: 1 port (4-bit).
Bidirection port
: 4 ports (P4, P6, P7, P8) are available by mask option. P4 is a high current port.
(P4.0 and TONE available by mask option. P4.1~P4.3 are shared with the input/
output of RFO.) P6, P7 and P8 are shared with SEG15-SEG26.
12-bit timer
: One 12-bit timer is programmable for timer.
High speed counter
: The high speed counter includes one 8-bit high speed counter, one 12-bit general
counter and a resistor frequency oscillator. It has resistor to frequency oscillation
mode, melody mode and auto load timer mode.
Built-in time base counter: 22 stages.
Subrountine nesting
: Up to 13 levels.
Interrupt
: External interrupt . . . . . . 2 input interrupt sources.
Internal interrupt . . . . . . 2 timer overflow interrupts,
1 time base interrupt.
LCD driver
: 27x3 to 15x3 dots available by mask option. 1/3, 1/2 and static three kinds of duty
(1/2 bias) selectable. The programming method of LCD driver is RAM mapping.
Built-in watch-dog-timer is available by mask option.
Built-in low battery detector.
Power saving function : STOP mode and IDLE mode.
Package type
: Chip form 50 pins.
QFP 52 pins (CQ).
QFP 100 pins (BQ).
