The Microduino RTC Module is a real time clock module based on NXP CMOS PCF8563. RTC module uses TWI/I2C interface for communication. Data can be backed up with the addtional AT24c32 EEPROM. With an onboard capacitor, the module can keep timing for minutes after power-off since the PCF8563 adopts an external crystal and a capacitor as well as an interrupt input which can trigger the interruption periodically.

Feature

Based on PCF8563 clock chip with century mark, second, minute, hour, day, week, month and year.
Use the IIC interface to communicate with the Core/Core+ module.
Use EEPROM AT24C32 with I2C interface.
With a low-power clock chip and the typical current value is 0.25μA.
With a super capacitor, the clock will keep running after power-off.
Open hardware circuit design and Arduino compatible programming development environment.
With a uniform Microduino interface standard and rich peripheral modules, it can easily connect with other Microduino modules and sensors.
2.54mm(0.1 inch) pin pitch, compatible with bread boards and pegboards.

Specification

Clock chip: PCF8563;
- Low-power CMOS real-time clock/calendar chip；
- Provide a programmable clock output, an interrupt output and a brown-out detector. All the addresses and data will have a serial transmission through the I2C bus interface;
- With the maximum bus speed of 400Kbits/s, the embedded word address register will generate increment automatically after reading and writing data every time.

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 bug, to have the replication cycle of millions lives and saved the data to 100 years with a write-protect function.
Super capacitor: XH414
- Provide a power-down timing function in a time slot.
