MCP79412Battery-Backed I2C Real-Time Clock/Calendar with Pre-Programmed EUI-64™ MAC ID | Clock/Timing | 4 | Active | 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. |
MCP79510Battery-Backed SPI Real-Time Clock/Calendar | Integrated Circuits (ICs) | 3 | Active | The MCP79510 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 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. This ID is preprogrammed with a 64-bit MAC Address, but it can also be ordered blank for the end user to program. |
