STMicroelectronics M48T08Y-10MH1E Timekeeper SRAM

The M48T08Y-10MH1E is a high-performance 64 Kbit Timekeeper SRAM manufactured by STMicroelectronics, designed to effectively address the needs of complex systems that require a reliable data and time-keeping solution. This integrated device combines a potent mix of static RAM with a built-in real-time clock/calendar and a battery within a single monolithic chip, ensuring data retention and accurate time-keeping even when the main power is turned off.

Operating at a voltage range of 4.5V to 5.5V, the M48T08Y-10MH1E provides a convenient memory capacity of 8K x 8 bits, which is ideal for applications in industrial control systems, telecommunications, and professional electronics where data integrity and time-stamping are critical. The access time of 100 ns allows for swift data retrieval, making it a suitable choice for high-speed operations.

The real-time clock/calendar feature of the M48T08Y-10MH1E provides seconds, minutes, hours, day, date, month, and year information, with the added benefit of leap year compensation valid up to the year 2100. The clock operates in either 24-hour or 12-hour format with an AM/PM indicator, adding to its versatility. A precision oscillator and crystal ensure accurate time-keeping, making it a reliable time reference.

The integrated battery with a lifespan of over 10 years ensures data retention and clock functionality for an extended period without external power. This feature is crucial for mission-critical systems where data loss cannot be tolerated. The self-contained battery and crystal in the M48T08Y-10MH1E also simplify the design and increase the reliability of the overall system by reducing the number of external components required.

Furthermore, the device features programmable alarm and interrupt functions, which provide additional utility by allowing systems to schedule tasks or prompt attention when specific conditions are met. The package is a JEDEC standard 28-lead, 600 mil DIP, which is widely used and ensures compatibility with many socket types and easy integration into various designs.

In summary, the M48T08Y-10MH1E from STMicroelectronics is a robust, feature-rich timekeeper SRAM that offers a unique combination of volatile memory and non-volatile time-keeping capabilities, making it an excellent choice for a wide range of applications that require dependable long-term data and time management.
