Micro Crystal's modules are ideal for a variety of applications

Micro Crystal's RTC and temperature module RV-3032-C7 offers all standard RTC features: calendar and time from years to 100 seconds with extremely high accuracy of ±2.5 ppm, equivalent to ±0.22 seconds/day, over a wide temperature range. Accurate (±1°C) and high resolution (0.0625°C) temperature measurements are ideal for tracking heat drift or runaway. It supports a single I²C address and provides solutions to key design constraints related to timing accuracy, temperature sensor resolution and accuracy, power supply, positioning, size, and battery life.

This section allows setting high and low temperature threshold alarms with timestamp and interrupt functions. It also includes multiple additional features such as external event detection, data protection via password, EEPROM, RAM, and frequency output (Hz to MHz), all of which can be used in a tiny device. Extremely low power consumption (160na at 3 V), combined with an integrated battery backup switch and trickle charger, allows the use of multi-layer ceramic capacitors (MLCCS) and ulcers to provide longer backup times
