EM73461B
4-BIT MICRO-CONTROLLER FOR LCD PRODUCT
12.26.2001
Preliminary
GENERAL DESCRIPTION
EM73461B is an advanced single chip CMOS 4-bit micro-controller. It contains 4K/8K-byte ROM, 244-nibble
RAM, 4-bit ALU, 13-level subroutine nesting, 22-stage time base, two 12-bit timer/counters for the kernel
function. EM73461B also contains 6 interrupt sources, 1 input port, 2 bidirection ports, LCD display (32x4), and
one high speed timer/counter with melody output.
EM73461B has plentiful operating modes (SLOW, IDLE, STOP) intended to reduce the power consumption.
FEATURES
Operation voltage
Clock source
: 2.4V to 3.6V.
: Dual clock system. Low-frequency oscillator is Crystal or RC oscillator (32K Hz,
connect an external resistor) by mask option and high-frequency oscillator is RC
oscillator (connect an external resistor), or built-in internal oscillator.
: 109 powerful instructions for 4K ROM / 107 powerful instructoins for 8K ROM.
Instruction cycle time : 0.85μs for 9.2M or 1.7μs for 4.6M or 2μs for 4MHz. Selected by mask option (high
speed clock).
122 μs or 244μs by frequency double mask option for 32768 Hz (low speed clock).
ROM capacity
: 4096 X 8 bits / 8192 X 8 bits ROM are choosed by mask option.
RAM capacity
: 244 X 4 bits.
Input port
: 1 port (P0). P0(0..3) and IDLE releasing function are available by mask option.
Bidirection port
: 2 ports (P4, P8). P4.0 and SOUND is available by mask option. P4.1 is shared with
HTC external input. P8(0..3) and IDLE releasing function are available by mask
option.
12-bit timer/counter
: Two 12-bit timer/counters are programmable for timer, event counter and pulse width
measurement.
High speed timer/counter : One 8-bit high speed timer/counters is programmable for auto load timer, melody
output and pulse width measurement.
Built-in time base counter : 22 stages.
Subroutine nesting
: Up to 13 levels.
Interrupt
: External . . . . . 2 input interrupt sources.
Internal . . . . . . 2 Timer overflow interrupts, 1 time base interrupt.
1 high speed timer overflow interrupt.
LCD driver
: 32 X 4 dots, 1/4duty, 1/3duty, 1/2duty, static, 1/2 bias, 1/3 bias; 6 options selectable.
Power saving function : SLOW, IDLE, STOP operation mode.
Package type
: Chip form
61 pins.
Instruction set
APPLICATIONS
EM73461B is suitable for application in family applicance, consumer products, hand held games and the toy
controller.
