* This specification are subject to be changed without notice.
7.17.1998
GENERAL DESCRIPTION
EM73492 is an advanced single chip CMOS 4-bit micro-controller. It contains 4K-byte ROM, 244-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 EM73492 also contains 6 interrupt sources, 10 I/O ports (including
1 output port , 2 input ports and 7 bidirection ports) and a serial bidirection interface (SIO).
For the application in the telecom product, EM73492 also supports user the beep tone and DTMF function
and there is another additional 512x4 bits RAM for the repertory dailing data storage.
Except low-power consumption and high speed, EM73492 also has sleep and hold mode operation for power
saving function.
EM73492 is suitable for appliaction in telecom products and family appliances.
