Stmicroelectronics (M48T02-150PC1) RTC, Timekeeper NVSRAM, Parallel

RTC, Timekeeper NVSRAM, Parallel, 4.75 V to 5.5 V, DIP-24 Product Overview The M48T02-150PC1 is a 16kb Non-volatile Static RAM and Real-time Clock which is pin and functional compatible with the DS1642. The M48T02 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 is a non-volatile pin and function equivalent to any JEDEC standard 2kb 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 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 Applications Security, Communications & Networking Product Information Date Format: YY-MM-DD-dd Clock Format: HH:MM:SS Clock IC Type: Timekeeper Supply Voltage Min: 4.75V Supply Voltage Max: 5.5V Clock IC Case Style: DIP No. of Pins: 24Pins IC Interface Type: Parallel Operating Temperature Min: 0°C Operating Temperature Max: 70°C
