Description

mCookie-RTC is a clock module adopting IIC interface communication, which can acquire time. With an onboard capacitor, RTC module can keep timing for several times after power disconnected.

Features

Marked with century flag, second, minute, hour, day, week, month and year;
Adopt I2C communication with the core modules;
Own EEPROM memory chip with I2C interface.
Low-power clock chip with typical 0.25μA current value and a super capacitor, capable of keeping the module running even after power disconnected;

Specification

EEPROM chip?AT24C32
- Provide 32,768 EPROM serial power, which can be organized with a length of 4096 words × 8-bit;
- Cascade feature allows AT24C32 to articulate eight devices on the same I2C bus, to have the replication cycle of millions times and save the data to 100 years with a write-protect function.
Super capacitor: XH414
- Provide a power-down timing function in a time slot.
Clock chip: PCF8563
- Low-power CMOS real-time clock/calendar chip;
- Offer a programmable clock output, an interruption output and a power-fail detector. All addresses and data can have a serial transmission through I2C bus interface;
- The maximum bus speed is 400Kbits/s. The embedded word address register will generate increment after reading and writing data every time.
