Real-time Clock IC
OVERVIEW
The SM8577B is a CMOS serial-interface type real-
time clock IC that operates at 32.768 kHz. It
employs a 3-line serial interface to transfer time and
date data. It incorporates a supply-voltage detect
function to determine data validity/invalidity. It
features an output interrupt with 32 kHz or 1 Hz
output frequency. It is available in 8-pin SOPs.
