The MCP79412 general purpose I2C™Compatible real-time clock/calendar (RTCC) is highly integrated with nonvolatile memory and advanced features normally found in higher priced devices. These features include a battery switchover circuit for backup power, a timestamp to log power failures and digital trimming for accuracy. Using a low-cost 32.768 kHz crystal or other clock source, time is tracked in either a 12-hour or 24-hour format with an AM/PM indicator and timing to the second, minute, hour, day of the week, day, month and year. As an interrupt or wakeup signal, a multifunction open drain output can be programmed as an Alarm Out or as a Clock Out that supports 4 selectable frequencies. In addition, non-volatile memory is included along with a Unique ID in a locked section of EEPROM that is factory programmed with an EUI-48 MAC Address.
MPLAB® X Integrated Development Environment (IDE) is an expandable, highly configurable software program that incorporates powerful tools to help you discover, configure, develop, debug and qualify embedded designs for most of Microchip’s microcontrollers, microprocessors and digital signal controllers.
MPLAB X IDE works seamlessly with the MPLAB development ecosystem of
The MPLAB® PM3 Universal Device Programmer is easy to use and operates with a PC or as a stand-alone unit, and programs Microchip's entire line of PIC® devices as well as the latest dsPIC® DSC devices. When used standalone, data can be loaded and saved with the SD/MMC card (not included).
The MCP7941X RTCC PICtail™ Plus Daughter Board demonstrates the features and abilities of the MCP7941X and MCP7940X I²C™ Real-Time Clock/Calendar family in standard development platforms. By designing this daughter board with the PICtail Plus, PICtail and PICkit™ serial connectors, it will operate with the Explorer 16 Development Board, the PICDEM PIC18 Explorer Board, the...
