The MCP795W20 SPI RTCC is highly integrated with memory and advanced features normally found in higher priced devices. By starting with a basic real-time clock, digital trimming was added for higher accuracy, a battery switchover for backup power, a timestamp to log power failures and three types of memory, which includes SRAM, EEPROM and a blank unique ID in a locked section of EEPROM. The ID is blank in this device, but can also be ordered with a 48-bit or 64-bit MAC Address. By adding a watchdog timer and two programmable event detect inputs, lower power and more system robustness can be achieved by performing these functions in the RTCC, thus allowing the MCU to sleep for longer periods of time.
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 MCP795XX PICtail™ Plus Daughter Board demonstrates the features and abilities of the MCP795XX SPI Real-Time Clock/Calendar (RTCC) family in standard development platforms. This daughter board will support the full featured 14-pin MCP795W2X and MCP795W1X devices. By designing this daughter board with both PICtail and PICtail Plus connectors, it will operate with the Explorer 16...
