DS3232SN# Description

Short technical summary and product information.

The DS3232SN# from Analog Devices / Maxim Integrated is a highly accurate, temperature-compensated crystal oscillator (TCXO) with an integrated real-time clock (RTC) and 236 bytes of battery-backed SRAM. This device maintains accurate timekeeping even when the main power supply is interrupted, thanks to its battery backup input.

 

The RTC functionality includes seconds, minutes, hours, day, date, month, and year, with automatic leap year correction valid up to 2099. It supports both 24-hour and 12-hour formats with an AM/PM indicator. The DS3232SN# also provides two programmable time-of-day alarms and a programmable square-wave output. Communication is handled via a fast 400kHz I2C bidirectional bus.

 

With an operating temperature range of -40°C to +85°C and an accuracy of ±2ppm from 0°C to +40°C, this RTC is suitable for demanding applications. It operates on a voltage range of 2.3V to 5.5V and consumes low power, typically between 120µA and 160µA at 3.3V to 5.5V.

 

The DS3232SN# is supplied in a 20-pin SOIC package with a surface mount type. Its integrated crystal resonator enhances long-term accuracy and reduces component count in manufacturing.
