Microchip MCP79412-I/SN

时钟/日历警报器，闰年，方波输出，SRAM，唯一 ID64B，1Kb

Overview

The MCP79412-I/SN is a general purpose I²C™Compatible Real-Time Clock/Calendar (RTCC) is highly integrated with non-volatile memory. This features a battery switchover circuit for backup power, a timestamp to log power failures and digital trimming for accuracy. Using a 32.768kHz crystal or other clock source, time is tracked in either a 12 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 multi-function 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 an unique ID in a locked section of EEPROM that is factory programmed with an EUI-48 MAC address.
