STMicroelectronics M48T35AV-10MH1 Timekeeper SRAM

The STMicroelectronics M48T35AV-10MH1 is a 256 Kbit (32K x 8) Timekeeper SRAM, which integrates a highly reliable, low-power SRAM with a precision real-time clock (RTC) in a single monolithic package. This innovative product is designed to maintain accurate timekeeping while providing non-volatile data storage, making it an ideal solution for a wide range of applications in industrial, telecommunications, and consumer electronics where the maintenance of accurate time and data integrity is crucial.

One of the standout features of the M48T35AV-10MH1 is its built-in lithium battery, which ensures that timekeeping and SRAM data are maintained for over 10 years in the absence of an external power supply. This self-contained energy source makes the device particularly useful in systems that require long-term data retention without the need for external power or periodic battery replacement.

The real-time clock of the M48T35AV-10MH1 provides seconds, minutes, hours, day, date, month, and year information, with the added benefit of automatic leap year compensation up to the year 2100. This high level of accuracy is essential for applications that require precise time-stamping or scheduling functions.

Operating at a speed of 10MHz, the M48T35AV-10MH1 offers fast access times, allowing efficient read and write operations to the SRAM, which is critical for high-performance systems. The device operates within a temperature range of 0°C to 70°C, ensuring reliability and stability across various environmental conditions.

The M48T35AV-10MH1 comes in a 28-pin, 600 mil DIP package, which is widely accepted in the industry and compatible with standard sockets, making it easy to integrate into existing designs. Additionally, the device features a software-controlled write protection mechanism, providing an extra layer of security against inadvertent data alteration.

In summary, the STMicroelectronics M48T35AV-10MH1 is a versatile, reliable, and essential component for systems requiring accurate timekeeping combined with non-volatile data storage, offering a convenient and long-lasting solution for a multitude of electronic applications.
