EM73290
4-BIT MICRO-CONTROLLER FOR GENERAL PURPOSE PRODUCT
GENERAL DESCRIPTION
EM73290 is an advanced single chip CMOS 4-bit micro-controller. It contains 2K-byte ROM, 116-nibble RAM,
4-bit ALU, 13-level subroutine nesting, 22-stage time base, two independent 12-bit timer/counters and one data
pointer (DP) for the kernel function, and the EM73290 also contains 5 interrupt sources, 7 I/O ports (including
2 output ports for LED driving , 1 input port and 4 bidirection I/O ports).
Except low-power consumption and high speed, EM73290 also has sleep and hold mode operation for power
saving.
EM73290 is suitable for application in family appliance, consumer products and toy controller.
