This chip is a 256Bit SRAM with external battery support. It's pupose is to save a few bits content over power-cycles of the machine it's build into.Notes: Vdd can be applied to a 2.8..3V battery to save the RAM state even if the onewire parasite power fails or the onewire is disconnected. The DS2224 is a similar chip with 32 Bit ROM and 224 Bit RAM Both the DS2223 and DS2224 chips seem discontinued by Maxim IC. Use the DS2423 chip, which provides additional features instead. Please note the DS2423 is not pin-compatible to the DS2223! Author: Orginal device and description from Giovanni Varasano <email@example.com>
