STMicroelectronics M48T35AV-10MH6E Timekeeper SRAM

The M48T35AV-10MH6E is a high-quality, 256 Kbit (32K x 8) Timekeeper SRAM designed and manufactured by STMicroelectronics. This integrated battery-backed SRAM and real-time clock (RTC) component is a versatile solution for applications requiring reliable data storage and precise timekeeping functionalities. The device is particularly well-suited for use in a wide range of industrial, telecommunications, and consumer electronics where maintaining accurate time and preserving data integrity during power loss is critical.

One of the key features of the M48T35AV-10MH6E is its integrated, long-life power-fail deselect circuitry, which automatically switches to the battery supply when a power failure is detected, ensuring that timekeeping and SRAM operations continue uninterrupted. The device operates at an access time of 100ns, which makes it an excellent choice for systems that require fast data retrieval and storage. It is designed to work with a 3.3V power supply, providing an energy-efficient solution for modern electronics.

The Timekeeper SRAM comes in a 28-pin, 600 mil SOIC package, making it easy to integrate into a variety of printed circuit board designs. It features a standard SRAM interface for data access, while the RTC provides seconds, minutes, hours, day, date, month, and year information, with automatic leap year compensation up to the year 2100. The clock accuracy is maintained within ±1 minute per month at 25°C.

With the M48T35AV-10MH6E, users benefit from the convenience of a self-contained battery and crystal within the same package, which significantly simplifies the design process and reduces the component count on the board. The device is also equipped with an automatic power-down feature when the chip is deselected, further enhancing its energy efficiency.

Overall, the STMicroelectronics M48T35AV-10MH6E Timekeeper SRAM is a reliable, high-performance solution for systems that require both non-volatile memory and real-time clock capabilities in a compact, integrated package.
