SM8580AM
NIPPON PRECISION CIRCUITS—1
NIPPON PRECISION CIRCUITS INC.
Real-time Clock IC with 4-bit Interface
and Built-in Temperature Sensor
OVERVIEW
The SM8580AM is a real-time clock IC based on a 32.768 kHz crystal oscillator, which features a 4-bit paral-
lel interface for communication with an external microcontroller.
It comprises second-counter to year-counter clock and calendar circuits that feature automatic leap-year adjust-
ment up to year 2099, alarm and timer interrupt functions, clock counter change detect functions, ±30-second
correction function, time error correction function, and built-in temperature sensor.
The 4-bit parallel interface is compatible with general-purpose SRAM over a high-speed bus.
