GENERAL DESCRIPTION
EM73201 is an advanced single chip CMOS 4-bit micro-controller. It contains 2K-byte ROM, 52-nibble RAM,
4-bit ALU, 13-level subroutine nesting, 22-stage time base, one 12-bit timer/counter for the kernel function.
EM73201 also contains 5 interrupt sources, 4 I/O ports (including 1 input port, 1 output port for LED driving,
2 bidirection I/O ports) built-in watch-dog-time counter and one high frequency clock output for modulating
infrared signal.
Except low-power consumption and high speed, EM73201 also have a sleep and hold mode operation for the
power saving function.
EM73201 is suitable for application in family appliance, consumer products and toy controller.
