Real-time clock module based on the PCF85063A IC for independent timekeeping and date tracking. It communicates via I2C at a fixed 0x51 address and provides an alarm function, INT interrupt output, and programmable clock output. An onboard battery holder maintains timekeeping when the main power supply is disconnected. Soldered 333051

Description

The device Real time clock RTC PCF85063A breakout by Soldered uses the PCF85063A RTC IC from NXP for independent timekeeping and date tracking. An external 32.768kHz crystal provides the clock source. The board can be used in data loggers, time-controlled devices, automation systems, and applications that require timekeeping independently of the main microcontroller.

The board features an onboard backup battery holder, allowing timekeeping to continue when the main power supply is disconnected. The backup battery is not included. The RTC also provides an alarm function connected to the INT output, which can generate an interrupt and wake a microcontroller from sleep mode.

Communication is handled through the I2C bus at a fixed address of 0x51. The board provides SDA and SCL pins as well as 2 Qwiic connectors for solderless connection to compatible modules. The CLK-OUT pin provides a programmable square-wave clock signal, while CLK-OE controls the clock output.

The PCF85063A IC operates over a 0.9–5.5V voltage range, while the board design supports systems using 3.3V and 5V supplies. Board dimensions are 38 × 22mm. The 3.2mm mounting holes are designed for M3 screws.
