Product Description

If you're looking for an all-in-one solution at low supply voltages with good current consumption performance the RV852C3 fits the bill. With supply voltages as low as 1.2V, and current consumption as low as only 130nA in time-keeping mode the RV8523C3 module can save time and procurement costs.

Featuring I2C bus interface and good shock and vibration performance, this module is also available with AEC-Q200 qualification and full PPAP documentation on request. If you're looking for something with cutting-edge power consumption you may wish to consider the RV1805C3, or for an ultra-miniature package with highly competitive pricing the RV4162C7.
