ST M48T35 M48T35Y 5 V 256 Kbit (32 Kb x 8) TIMEKEEPER SRAM handbook
M48T35 and M48T35Y are products that integrate ultra-low-power SRAM, real-time clock, power-fail control circuit, and battery. They have BYTEWIDE RAM-like clock access, BCD-coded year, month, day, date, hours, minutes, and seconds, frequency test output for the real-time clock, automatic power-fail chip deselect, and WRITE protection.
