TIMEKEEPER® SRAM, 16 Kb (2 K x 8), 4.75 ... 5.5 V, PCDIP24

5.0 V, 16 Kbit (2 Kb x 8) TIMEKEEPER® SRAM

Features
- Integrated, ultra low power SRAM, real-time clock, and power-fail control circuit
- 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
- WRITE protect voltages (VPFD = power-fail deselect voltage):
- M48T02: Vcc = 4.75 to 5.5 V; 4.5 V = Vpfd = 4.75 V
- M48T12: Vcc = 4.5 to 5.5 V; 4.2 V = Vpfd = 4.5 V
- Self-contained battery and crystal in the CAPHAT™ DIP package
- Pin and function compatible with JEDEC standard 2 K x 8 SRAMs
- RoHS compliant
