M48T02-200PC1 Tımeeeper Sram

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):
