Summary description

The M48T58/Y TIMEKEEPER? RAM is a 8Kb 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.

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

■ Frequency test output for real time clock

■ Automatic power-fail chip deselect and write protection

■ Write protect voltages (VPFD = power-fail deselect voltage):

– M48T58: VCC = 4.75 to 5.5V 4.5V ≤ VPFD ≤ 4.75V

– M48T58Y: VCC = 4.5 to 5.5V 4.2V ≤ VPFD ≤ 4.5V

■ Self-contained battery and crystal in the CAPHAT? dip package

■ Packaging includes a 28-lead SOIC and SNAPHAT? top (to be ordered separately)

■ SOIC package provides direct connection for a snaphat housing containing the battery and crystal

■ Pin and function compatible with JEDEC standard 8 Kb x8 SRAMs

■ RoHS compliant

– Lead-free second level interconnect
