Tổng Quan Sản Phẩm
PCF85263AT/AJ is a tiny RTC/calendar with an alarm function, battery switch-over, time stamp input, and I2C-bus. It is a CMOS Real-Time Clock (RTC) and calendar optimized for low power consumption and with automatic switching to battery on main power loss. The RTC can also be configured as a stop-watch (elapsed time counter). Three-time log registers triggered from battery switch-over as well as input-driven events. Featuring a clock output and two independent interrupt signals, two alarms, an I2C-bus interface, and quartz crystal calibration. Typical applications are printers and copiers, electronic metering, digital cameras, white goods, elapsed time counter, network powered devices, battery backed up systems, data loggers, digital voice recorders, mobile equipment, accurate high duration timer.
- Stop-watch mode for elapsed time counting from 100th seconds to 999 999hours
- Two independent alarms, battery back-up circuit, watchdog timer, three timestamp registers
- Two independent interrupt generators plus predefined interrupts at every second, minute, or hour
- Frequency adjustment via programmable offset register
- Clock operating voltage range from 0.9V to 5.5V
- Low current is 0.28μA typical at VDD = 3.0V and Tamb = 25°C
- 400KHz two-line I2C-bus interface (at VDD = 1.8V to 5.5V)
- Configurable oscillator circuit for a wide variety of quartzes: CL = 6pF, CL = 7pF, and CL = 12.5pF
- SO8 package
- Ambient temperature range from -40°C to +85°C
