EM73963A 4-BIT MICRO-CONTROLLER FOR LCD PRODUCT 6.14.2001 GENERAL DESCRIPTION EM73963A is an advanced single chip CMOS 4-bit micro-controller. It contains 16K-byte ROM, 372-nibble RAM, 4-bit ALU, 13-level subroutine nesting, 22-stage time base, two 12-bit timer/counters for the kernel function. EM73963A also equipped with 5 interrupt sources, 3 I/O ports (including 1 input port and 2 bidirection ports), LCD display (40x8), built-in sound generator. It's low power consumption and high speedfeature are further strengten with DUAL, SLOW, IDLE and STOP operation mode for optimized power saving. FEATURES Operation voltage : 2.4V to 5.5V. Clock source : 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). ROM capacity : 16K X 8 bits. RAM capacity : 372 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 ports (P4, P8). P4.0 and SOUND are available by mask option. IDLE/STOP release 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. Subroutine nesting : Up to 13 levels. Interrupt : External . . . . . 2 input interrupt sources. Internal . . . . . . 2 Timer overflow interrupts. 1 Time base interrupt. LCD driver : 40 X 8 dots, 1/8 duty, 1/5 bias. Sound effect : Tone generator, random generator and volume control. Power saving function :SLOW, IDLE, STOP operation modes. Package type : Chip form 69 pins. |
