Product Summary

The M48T35Y-70PC1 is a 32Kb x8 non-volatile static RAM and real time clock. The monolithic chip is available in two special packages to provide a highly integrated battery backed-up memory and real time clock solution. The M48T35Y-70PC1 is a non-volatile pin and function equivalent to any JEDEC standard 32Kb x8 SRAM. The M48T35Y-70PC1 is 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 writes that can be performed.

Parametrics

M48T35Y-70PC1 absolute maximum ratings: (1)TA, Ambient Operating Temperature, Grade 1: 0 to 70℃; Grade 6: –40 to 85℃; (2)TSTG, Storage Temperature (VCC Off, Oscillator Off): –40 to 85℃; (3)TSLD, Lead Solder Temperature for 10 seconds: 260℃; (4)VIO, Input or Output Voltages: –0.3 to 7 V; (5)VCC, Supply Voltage: –0.3 to 7 V; (6)IO, Output Current: 20 mA; (7)PD, Power Dissipation: 1 W.

Features

M48T35Y-70PC1 features: (1)integrated ultra low power SRAM, real time clock, power-fail control circuit and battery; (2)bytewide ram-like clock access; (3)bcd coded year, month, day, date, hours, minutes and seconds; (4)frequency test output for real time clock; (5)automatic power-fail chip deselect and write protection; (6)write protect voltages (VPFD = Power-fail Deselect Voltage): 4.2V ≤ VPFD ≤ 4.5V; (7)self-contained battery and crystal in the caphat DIP package; (8)SOIC package provides direct connection for a snaphat housing containing the battery and crystal; (9)snaphat housing (battery and crystal) is replaceable; (10)pin and function compatible with jedec standard 32Kb x8 SRAMs.
