Miniature real-time clock family operates at low voltages down to 0.9-V
With a size of 2 x 3 x 0.75 mm and a pin pitch of 0.5 mm, the PCF85063TP tracks time and date from seconds to years, and is one of the smallest RTCs in the world. In addition to electronic frequency tuning, the RTCs can also be programmed to generate an interrupt every 30 or 60 seconds, communicating via a Fast-mode I2C-bus operating up to 400 kHz.
Measuring at 2.6 x 2.6 x 0.5 mm, the PCF85063ATL and PCF85063BTL are similarly small, with additional features including an alarm facility and a countdown timer controlled via an I2C or SPI bus. Ideal for battery-powered operation (IDD ~0.22 μA), the PCF85063 can be used for a wide range of timing functions in compact mobile devices.
Availability and Pricing
The PCF85063 family of real-time clocks is in volume production and available immediately. Pricing for the PCF85063TP is $0.26 per piece in 10k quantities.
