Wide Working Voltage: 2.0 ~ 5.5V
Single-byte and multi-byte transmission for clock or RAM data read / write
TTL-compatible (Vcc=5V)
Working Temperature: 0 to +70 Deg C
32.768KHz crystal oscillator
Equipped with a 260mAh CR2032 button battery, not rechargeable
Overall Size: Approx. 44 x 23 x 11mm
Wiring:
Vcc - +5V / 3.3V
GND - GND
