DETAILED PIN DESCRIPTION
OVERVIEW
The DS2434 has five major components: 1) Scratchpad Memory, 2) Nonvolatile Memory, 3) On-board
SRAM, 4) Temperature Sensor, and 5) ID Register. All data is read and written least significant bit first.
Access to the DS2434 is over a 1-Wire interface. Charging parameters and other data such as battery
chemistry, gas gauge information, and other user data would be stored in the DS2434, allowing this
information to be permanently stored in the battery pack. Nonvolatile (E
if the battery goes dead; as long as the battery remains within typical charge/discharge operating range,
the SRAM provides battery-backed storage of information.
