MCP7940N Real-Time Clock/Calendar (RTCC)

Microchip Technology MCP7940N Real-Time Clock/Calendar (RTCC) uses digital timing compensation for an accurate clock/calendar, a programmable output control for versatility, and a power sense circuit that automatically switches to the backup supply. Using a low-cost 32.768kHz crystal, it tracks time using several internal registers. For communication, the MCP7940N uses the I2C bus. The clock/calendar automatically adjusts for months with fewer than 31 days, including corrections for leap years. The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator and settable alarm(s) to the second, minute, hour, or day of the week, date, or month. Using the programmable CLKOUT, frequencies of 32.768kHz, 8.192kHz and 4.096kHz and 1Hz can be generated from the external crystal. The device is fully accessible through the serial interface while VCC is between 1.8V and 5.5V, but can operate down to 1.3V for timekeeping and SRAM retention only.

实时时钟

Microchip实时时钟从基本的低成本器件到各种中档器件,不一而足。这些高度集成的器件设有可用数量的非易失性存储器,并结合了诸多特性,在单个电池供电的时钟设备中工作时,这些特性极为有效。借助I2C和SPI RTCC,可凭借较低价格器件支持各类应用,这类器件的特性更少、性能更低。
