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

RTC, Timekeeper NVSRAM, Parallel, 4.75 V to 5.5 V, DIP-24Product OverviewThe M48T02-150PC1 is a 16kb Non-volatile Static RAM and Real-time Clock which ispin and functional compatible with the DS1642. The M48T02 button cell hassufficient capacity and storage life to maintain data and clock functionalityfor an accumulated time period of at least 10 years in the absence of power overthe operating temperature range. It is a non-volatile pin and functionequivalent to any JEDEC standard 2kb x 8 SRAM. It also easily fits into manyROM, EPROM and EEPROM sockets providing the non-volatility of PROMs without anyrequirement for special write timing or limitations on the number of write thatcan be performed.Integrated ultralow power SRAM, real-time clock and power-fail control circuitBYTEWIDERAM-like clock accessBCD coded year, month, day, date, hours, minutes and secondsTypical clock accuracy of ±1 minute a month at 25°CSoftware controlled clock calibration for high accuracy applicationsAutomatic power-fail chip deselect and WRITE protectionApplicationsSecurity, Communications & NetworkingProduct InformationDate Format: YY-MM-DD-ddClock Format: HH:MM:SSClock IC Type: TimekeeperSupply Voltage Min: 4.75VSupply Voltage Max: 5.5VClock IC Case Style: DIPNo. of Pins: 24PinsIC Interface Type: ParallelOperating Temperature Min: 0°COperating Temperature Max: 70°C
