EM73480
4-BIT MICRO-CONTROLLER FOR LCD PRODUCT
Preliminary
GENERAL DESCRIPTION
EM73480 is an advanced single chip CMOS 4-bit micro-controller. It contains 4K-byte ROM, 224-nibble RAM,
4-bit ALU, 13-level subroutine nesting, 22-stage time base, two 12-bit timer/counters for the kernal function.
EM73480 also contains 6 interrupt sources, 1 input port, 3 bidirection I/O ports, LCD display (32x4), built-in
sound generator, one high speed timer/counter and 21 sec speech synthesizer (6K sample rate).
EM73480 has plentiful operating modes (SLOW, IDLE, STOP) intended to save power.
