Stmicroelectronics (M48T35Y-70PC1) RTC, TIMEKEEPER® RAM, 32Kbx8

Product Overview The M48T35Y-70PC1 is a 32kb x 8 TIMEKEEPER® Non-volatile Static RAM and Real-time Clock. The monolithic chip is to provide a highly integrated battery-backed memory and real-time clock solution. The RAM is a non-volatile pin and function equivalent to any JEDEC standard 32kb 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. The 28-pin, 330mil SOIC provides sockets with gold plated contacts at both ends for direct connection to a separate SNAPHAT® housing containing the battery and crystal. 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 Frequency test output for real-time clock Automatic power-fail chip deselect and WRITE protection SNAPHAT® housing (battery and crystal) is replaceable Applications Security, Communications & Networking Product Information Date Format: YY-MM-DD-dd Clock Format: HH:MM:SS Clock IC Type: Timekeeper Supply Voltage Min: 4.5V Supply Voltage Max: 5.5V Clock IC Case Style: DIP No. of Pins: 28Pins IC Interface Type: Parallel Operating Temperature Min: 0°C Operating Temperature Max: 70°C
