The M48T35Y-70MH1E is a 256 Kbit (32K x 8) Timekeeper SRAM designed by STMicroelectronics, which integrates a highly reliable, low-power SRAM with a precision real-time clock (RTC). This integrated package provides a convenient and robust solution for maintaining critical data and accurate timekeeping in the event of a system power failure.

Key Features

• Integrated Battery: The device comes with a self-contained battery that provides over 10 years of data retention and a reliable clock functionality, even when the main power is off.
• Real-Time Clock (RTC): The RTC tracks time with precision in hours, minutes, and seconds, and it includes a day of the week, date, month, and year with leap-year compensation valid up to 2100.
• Speed and Voltage: This Timekeeper SRAM operates at a speed of 70ns and a supply voltage of 3.3V, making it suitable for a wide range of applications.
• Automatic Power-Fail Chip Deselect and Write Protection: Writes are inhibited during power-down and power-up, providing a high level of data security.
• Byte-Wide Interface: The SRAM offers simple integration with most microcontrollers via its byte-wide interface.
• Package: The device is housed in a 28-pin, 600 mil SOIC package, providing a compact form factor for space-constrained applications.
