exact items shown - lot of
three M48T35AV clock/calendar/eeprom chips. the data sheet for them is here: https://www.st.com/resource/en/datasheet/m48t35y.pdf
5 V, 256 Kbit (32 Kb x 8) TIMEKEEPER® SRAM
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):
– M48T35: VCC = 4.75 to 5.5 V;
4.5 V ≤ VPFD ≤ 4.75 V
– M48T35Y: VCC = 4.5 to 5.5 V;
4.2 V ≤ VPFD ≤ 4.5 V
■ 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 32 Kb x 8 SRAMs
■ RoHS compliant
– Lead-free second level interconnect
Note to me: top small gray drawer
I normally ship within 24 hours of your order, but the post office does not always initiate tracking when I put the packages in the drop off box.
