Overview

The QCIOT-RTC22MPOCZ board features the low-power ISL12022M Real-Time Clock (RTC) devices with an embedded temperature sensor and 32.768kHz quartz crystal. The built-in automatic switchover to battery backup for power failure draws only 1.6μA extending battery life while providing continuous power to the 128-byte SRAM, oscillator, and RTC registers.

The RTC tracks time with separate registers for hours, minutes, and seconds. The calendar registers track date, month, year, and day of the week and is accurate through 2099 with automatic leap year correction.

The board provides a standard Pmod™ Type 6A (Extended I²C) connection for the onboard devices to plug into any MCU evaluation kit with a matching connector. QCIOT- RTC22MPOCZ features Pmod connectors on both sides of the board allowing additional Type 6/6A boards to be connected in a daisy-chained solution with multiple QCIOT boards on the same MCU Pmod connector.
