Product Overview

The M48T18-100PC1 is a TIMEKEEPER® Non-volatile Static RAM and Real-time Clock which is pin and functional compatible with the DS1642. This is a non-volatile pin and function equivalent to any JEDEC standard 8K x 8 SRAM. 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 write that can be performed.
  • Integrated ultralow power SRAM, real-time clock, power-fail control circuit and battery
  • BYTEWIDE™RAM-like clock access
  • BCD coded year, month, day, date, hours, minutes and seconds
  • 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
  • 100ns Speed
