The MCP795W12 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 unique ID in a locked section of EEPROM that is preprogrammed with a 48-bit MAC Address that can also be ordered blank for the end user to program. By adding a watchdog timer and two programmable event detect inputs, lower power and more system robustness can be achieved by off-loading MCU functions and allowing it 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...
