M41T93SMY6F ST RTC | 18-SOX | SPI, 2.0-5.5V, -40~85°C

Product Overview

The M41T93SMY6F is a low-power serial real-time clock (RTC) with an integrated 32.768 kHz crystal oscillator and a 32-byte static RAM. Manufactured by STMicroelectronics, this device is housed in an 18-pin SOX package (300 mil width). It provides a full binary-coded decimal (BCD) clock/calendar including seconds, minutes, hours, day, date, month, and year with leap year compensation up to 2100. The RTC operates over a wide voltage range of 2.0V to 5.5V and is guaranteed over the industrial temperature range of -40°C to +85°C. Communication is via an SPI bus with a maximum clock frequency of 5 MHz.
