STMicroelectronics M48T35AV-10PC1 Timekeeper SRAM

The M48T35AV-10PC1 is a high-performance, 256 Kbit (32K x 8) Timekeeper SRAM designed by STMicroelectronics to provide a convenient and reliable solution for integrating a battery-backed non-volatile memory and a real-time clock (RTC) in a single package. This integrated device is particularly suitable for applications requiring data and time storage without the risk of data loss upon power failure.

Key Features

• Integrated Power-Supply and Crystal: The device includes a built-in 3 V lithium battery and a quartz crystal, which ensures that the real-time clock continues to function and the SRAM retains data even when the main power is lost.
• Real-Time Clock (RTC): The M48T35AV-10PC1 features a real-time clock that counts seconds, minutes, hours, day, date, month, and years with leap-year compensation up to the year 2100.
• Automatic Power-Fail Chip De-Select and Write-Protection: This feature ensures data integrity by automatically switching to the battery supply during a power fail condition and write-protecting the memory.
• Low Power Consumption: Designed for energy efficiency, the device operates with very low power consumption, making it ideal for battery-powered systems.
• 10 ns Access Time: The SRAM provides a fast access time of 10 ns, facilitating quick data retrieval and storage, which is critical for high-performance computing tasks.
• 28-Pin DIP Package: The device is available in a 28-pin, 600 mil DIP package, which is easy to integrate into a variety of circuit boards and systems.

Applications

The M48T35AV-10PC1 is versatile and can be used in a wide range of applications, including:

• Industrial systems
• Embedded systems
• Communications equipment
• Network servers
• Medical devices
• Point-of-sale terminals

With its robust feature set, the M48T35AV-10PC1 from STMicroelectronics is a reliable choice for designers looking to incorporate both non-volatile memory and a real-time clock in their systems, ensuring data preservation and accurate timekeeping even in the event of a power interruption.
