The MK48T52B15 is a TIMEKEEPER^® RAM 8Kb 2.7V to 5.5V 28-Pin SOH from STMicroelectronics, a leading global semiconductor company. This integrated device combines a CMOS SRAM, a real-time clock (RTC), a power-fail control circuit, and a battery, all encapsulated in a single package. It is designed to provide a reliable, long-term, non-volatile memory solution with a built-in timekeeping functionality.

Key Features

• Integrated Power Supply: The MK48T52B15 includes an embedded lithium energy source and a power-fail control circuit, ensuring data retention and proper RTC operation during periods when the main power is unavailable.
• Real-Time Clock: The RTC provides seconds, minutes, hours, day, date, month, and year information. It also accounts for leap years up to the year 2100, ensuring accurate timekeeping for extended periods.
• Automatic Power-Fail Chip De-Select: When power levels drop below a predetermined threshold, the device automatically switches to its battery supply, ensuring no data loss or corruption occurs.
• Low Power Consumption: The device operates with a very low power consumption, making it suitable for battery-backed applications where power efficiency is crucial.
• Write Protect Function: A write-protect feature prevents inadvertent writes to the clock or memory, thus preserving the integrity of the data.
• Surface-Mount Package: The 28-pin SOH (Small Outline Horizontal) package allows for efficient use of board space, making it ideal for compact designs.

Applications

The MK48T52B15 is versatile and can be used in a wide range of applications, including:

• Industrial systems
• Telecommunication equipment
• Embedded systems
• Networking hardware
