Real Time Clock datasheet and documents for DS3232SN#T&R

DS3232SN#T&R

Real Time Clock Overview

The DS3232SN#T&R is a low-cost temperature-compensated crystal oscillator (TCXO) with an integrated real-time clock (RTC) and 236 bytes of battery-backed SRAM. It maintains timekeeping via seconds, minutes, hours, day, date, month, and year registers, including leap-year compensation valid to 2099. The device operates on a 2.3V to 5.5V supply and features a fast 400kHz I2C interface. Accuracy is specified at ±2ppm from 0°C to +40°C and ±3.5ppm from -40°C to +85°C. It includes two programmable alarms, a square-wave output, and a digital temperature sensor with ±3°C accuracy.

Real Time Clock Procurement Notes

Verify the specific suffix #T&R indicates tape-and-reel packaging when sourcing. Confirm the SN designation corresponds to the industrial temperature range (-40°C to +85°C). Ensure the source document explicitly lists this part number as active or available for the intended region.

Real Time Clock Selection Notes

Select the DS3232SN#T&R for applications requiring high long-term accuracy without external crystals. The industrial grade variant is suitable for environments ranging from -40°C to +85°C. Consider the 236-byte SRAM capacity for data logging needs. Verify I2C bus compatibility and voltage levels between 2.3V and 5.5V.

Real Time Clock Part Context

This component belongs to the DS3232 family of extremely accurate I2C RTCs. The 'SN' suffix denotes the industrial temperature range version in a 20-pin SO package. The '#T&R' suffix typically indicates reel packaging for surface-mount assembly. It integrates the crystal resonator, reducing piece-part count compared to discrete RTC solutions.
