DS2438
Page 1 (01h)
The second page, Page 1, contains the ICA, elasped time meter, and current offset data. Both the ETM
and ICA are volatile read/write locations so that they may be set, changed, or cleared by the host
software. Bytes 0-3 contain the ETM data, formatted as described in the “Operation - Elapsed Time
Meter” section. Byte 4 contains the 8-bit ICA. Bytes 5 and 6 contain the Offset Register data. Byte 7 is
reserved and will read out as all “1”s.
Page 2 (02h)
The third page of memory (Page 2) contains the Disconnect (first 4 bytes) and End of Charge (remaining
4 bytes) timestamps. This page is volatile and read/write. Refer to the “Operation – Elapsed Time Meter”
section for the formatting of these locations.
Pages 3-7 (03h - 07h)
The remainder of the memory in the DS2438 (Pages 3 through 7) is backed with EEPROM. This memory
provides 40 bytes of user memory which may be used to carry any information the user wishes to store.
Additionally, the CCA/DCA information is stored in bytes 4-7 of page 7 if the DS2438 is configured
appropriately. If the CCA/DCA is used, page 7 should not be written to or current accumulator data will
be overwritten. See “Operation-Current Accumulators” for details.
