Product Overview

The M48T02-70PC1 is a TIMEKEEPER® RAM 2Kb x 8 non-volatile static RAM and Real-time Clock IC which is pin and functional compatible with the DS1642. The button cell has sufficient capacity and storage life to maintain data and clock functionality for an accumulated time period of at least 10 years in the absence of power over the operating temperature range. It also easily fits into many ROM, EPROM and EEPROM sockets, providing the non-volatility of PROMs without any requirement for special WRITE timing or limitations on the number of WRITEs that can be performed.
  • Integrated, ultralow power SRAM, real-time clock and power-fail control circuit
  • RAM-like clock access
  • Typical clock accuracy of ±1 minute a month, at 25°C
  • Software controlled clock calibration for high accuracy applications
  • Automatic power-fail chip deselect and WRITE protection
Negative undershoots below -0.3V are not allowed on any pin while in the battery backup mode.
