The BQ3285LDSS is an integrated circuit (IC) component developed by Texas Instruments. It is a low-power real-time clock (RTC) with built-in non-volatile SRAM memory. This device is commonly used in various electronic applications that require accurate timekeeping along with data storage capabilities.
One of the key features of the BQ3285LDSS is its extremely low power consumption. It operates on a supply voltage as low as 1.8V and consumes only a fraction of current, making it ideal for battery-powered devices. The low-power design ensures longer battery life and reduced overall power consumption.
The BQ3285LDSS incorporates a highly accurate RTC with a built-in temperature-compensated crystal oscillator (TCXO), providing precise timekeeping even in varying environmental conditions. The temperature compensation feature ensures that the clock remains accurate despite fluctuations in temperature.
Another notable feature of this IC component is its non-volatile SRAM memory. It has 270 bytes of non-volatile (NV) memory, which can be used to store critical data, such as system configuration settings, calibration values, or user preferences. The non-volatile nature of the memory ensures that the data remains intact even during power loss or system shutdowns.
To interface with external microcontrollers or other digital devices, the BQ3285LDSS supports both I2C and SPI serial interfaces
