EM73P461A
4-BIT MICRO-CONTROLLER FOR LCD PRODUCT
12.27.2001
Preliminary
GENERAL DESCRIPTION
EM73P461A is an advanced single chip CMOS 4-bit one-time programming (OTP) 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. EM73P461A also contains 6 interrupt sources, 1 input port, 2 bidirection ports,
LCD display (32x4), and one high speed timer/counter with melody output.
EM73P461A 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).
: 109 powerful instructions for 4K ROM / 107 powerful instructoins for 8K ROM.
Instruction cycle time : Up to 2us for 4 MHz (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
