Description
The M48T35AV TIMEKEEPER RAM is a 32Kbit x 8 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 M48T35AV 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 WRITEs that can be performed.
The 28-pin, 600mil DIP CAPHATTM houses the M48T35AV silicon with a quartz crystal and a long-life lithium button cell in a single package.
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. The unique design allows the SNAPHAT battery package to be mounted on top of the SOIC package after the completion of the surface mount process. Insertion of the SNAPHAT housing after reflow prevents potential battery and crystal damage due to the high temperatures required for device surface-mounting. The SNAPHAT housing is keyed to prevent reverse insertion.
The SOIC and battery/crystal packages are shipped separately in plastic anti-static tubes or in tape & reel form.
Features
● Integrated, ultra low 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
● Battery low flag (BOK)
● Frequency test output for real-time clock
● Automatic power-fail chip deselect and write protection
● Write protect voltages (VPFD = Power-fail deselect voltage):
– M48T35AY: VCC = 4.5 to 5.5V 4.2V ≤ VPFD ≤ 4.5V
– M48T35AV: VCC = 3.0 to 3.6V 2.7V ≤ VPFD ≤ 3.0V
● Self-contained battery and crystal in the CAPHAT DIP package
● SOIC package provides direct connection for a SNAPHAT housing containing the battery and crystal
● SNAPHAT housing (battery and crystal) is replaceable
● Pin and function compatible with JEDEC standard 32Kbit x 8 SRAMs
● RoHS compliant – Lead-free second level interconnect
