DS1302ZN+T&R
Analog DevicesThe DS1302ZN+T&R is the tape-and-reel SOIC-8 code for the Analog Devices (Maxim) DS1302 trickle-charge real-time clock, in the industrial-grade N version rated from -40 C to +85 C. It counts seconds through years with leap-year compensation to 2100 over a simple three-wire serial interface, adds 31 bytes of scratchpad RAM and charges the backup battery or supercap through a programmable trickle charger, with dual supply pins so the clock keeps time when main power fails. The grade is the selection point on this page: the plain DS1302Z code is the commercial 0 C to +70 C part, while this ZN code is what outdoor meters, industrial loggers and wide-temperature equipment should carry on the BOM. Selection advice: the +T&R suffix is part of the Analog Devices ordering code for reel packing, and the trickle-charge resistor and diode settings must be programmed to match your backup cell. Parameters verified against Analog Devices documentation.
