ITEM NAME:DS1302 Really Time Watch Module with CR2032 Button Cell T1G6 DS1302 Really Time Watch Module with CR2032 Button Cell T1G6 31 x 8 RAM for notepad data storage Serial I/ O interface for minimum pin count Wide operating voltage: 2.0 ~ 5.5V Single-byte and multi-byte transmission for clock or RAM data read/ write TTL compatible (Vcc = 5V) The real-time clock module provides seconds, minutes, hours, days, date, month and year. The end of the month date is automatically considered for months with less than 31 days, including correction for leap years. This real-time clock module communicates with a microprocessor via a simple serial interface. The clock module operates in 24-hour or 12-hour format with AM/ PM indicator. Operating temperature: 0 to +70 Celsius 32.768 oscillator Equipped with a 260mAh CR2032 button cell, not rechargeable Overall size: approx. 44 x 23 x 11mm Material: Metal Wiring: Vcc + 5V/ 3.3V GND - GND CLK - P01 DAT - P02 RST - P00 Note: Do not reverse VCC and GND, or it will cause damage. It requires a pull-up resistor for P0 port of 51 MCU, if without the data line can connect to other port. Package Contents:1 x real time clock module Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm..It requires a pull-up resistor for P0 port of 51 MCU, if without the data line can connect to other port. The clock module operates in 24-hour or 12-hour format with AM/ PM indicator. Serial I/ O interface for minimum pin count.
