Ausverkauf! Microduino RTC Echtzeitmodul NXP CMOS PCF8563 TWI/I2C

Description

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.

Features

• 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

• 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.
• 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.
