EM73896
4-BIT MICRO-CONTROLLER FOR TELECOM PRODUCT
7.17.1998
GENERAL DESCRIPTION
EM73896 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 independent 12-bit timer/counters and one data
pointer(DP) for the kernel function. EM73896 also contains 6 interrupt sources, 9 I/O ports (including 1 input
port, 1 output port and 7 bidirection ports), direct LCD driver (4 kinds : static, 1/2, 1/3, 1/4 programmable duty
type), serial bidirection interface (SIO) and built-in watch-dog-timer counter.
For the application of telecom product, EM73896 also support user the melody generator and DTMF function
and there is another additional 512x4 bits RAM for the repertory dailing data storage.
Except low-power consumption and high speed, EM73896 is a dual clock system, which can work both in dual
clock mode or slow clock mode (real time clock) for power saving.
EM73896 is suitable for application in telecom products and family appliances.
