STMicroelectronics M48T35Y-70PC1 Timekeeper SRAM
The M48T35Y-70PC1 is a high-performance 256 Kbit (32K x 8) Timekeeper SRAM integrated circuit from STMicroelectronics. This precision device is designed to provide a reliable and efficient solution for electronic systems requiring a combination of volatile memory with a timekeeping feature. It is particularly well-suited for applications that demand accurate timekeeping alongside the need to store and retrieve data quickly.
One of the key features of the M48T35Y-70PC1 is its integrated, fully functional real-time clock (RTC) that keeps track of seconds, minutes, hours, days, date, month, and year information. The clock/calendar functionality is accurate up to the year 2100, with automatic leap year compensation. This feature ensures that the device can be used in applications where long-term accurate timekeeping is crucial.
The M48T35Y-70PC1 operates at a speed of 70ns, offering swift access to the SRAM, which is essential for high-speed data logging, industrial control systems, and other time-sensitive applications. The SRAM is backed up by an integrated, replaceable lithium battery that ensures data retention and the continuous operation of the clock/calendar during power loss situations. This battery-backed SRAM is a reliable choice for systems that cannot afford to lose data or timekeeping capabilities during power outages.
The device is packaged in a 28-pin PC1 (DIP) package, providing easy integration into a wide range of electronic systems. It features a 4.5V to 5.5V power supply voltage range, making it compatible with most 5V logic systems. Additionally, the M48T35Y-70PC1 offers a BYTE-WIDE™ interface, allowing for simple and direct connections to the microprocessor bus without the need for additional interfacing or glue logic.
With its combination of non-volatile memory and integrated RTC, the M48T35Y-70PC1 from STMicroelectronics is an excellent choice for applications in networking, telecommunications, data acquisition systems, and any other system that requires robust timekeeping and data storage capabilities.
For designers and engineers looking for a dependable memory and timekeeping solution, the M48T35Y-70PC1 offers the perfect combination of performance, reliability, and ease of integration.
