EM73866
4-BIT MICRO-CONTROLLER FOR LCD PRODUCT
8.12.1998
Preliminary
GENERAL DESCRIPTION
EM73866 is an advanced single chip CMOS 4-bit micro-controller. It contains 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.
EM73866 also contains 6 interrupt sources, 1 input port, 4 bidirection ports, LCD display (32x4), and built-in
watch-dog-timer counter.
EM73866 has plentiful operating modes (SLOW, IDLE, STOP) intended to reduce the power consumption.
FEATURES
Operation voltage
Clock source
: 2.2V ~ 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 capacitor).
