t1-t8 REGISTERS (64h-73h)
These registers hold the accumulated time values for the time/temperature histogram. t1 corresponds to
the time spent in histogram bin 1, t2 the time spent in bin 2, etc., where the bins are defined by the limits
set in TA-TG as shown in Figure 2. The format for the time value stored in these two-byte registers
depends upon the SAMPLE RATE, and is defined in the paragraph describing the SAMPLE RATE
parameter.
t REGISTER (74h-76h)
This 3-byte register is the elapsed time counter, formatted as follows:
The elapsed time counter has an LSB value of 1 minute; the total time, which the counter can
accommodate, is 224 minutes, or 31.92 years.
Issuing any protocol to the DS2435 prevents the incrementing of the elapsed time counter and histogram
registers until the protocol is cleared by issuing a reset. Therefore, it is imperative that any protocol
issued to the DS2435 be followed by a reset (either after the protocol, if it requires no data, or
immediately following the required data). This is necessary to avoid contention between the counter and
histogram writing process and external processes.
PAGE 5
The fifth page of memory holds the battery manufacturer ID number, a 2-byte counter for counting the
number of battery charge/discharge cycles, histogram bin limits, and sample rate.
ID REGISTER (80h and 81h)
The ID Register is a 16-bit ROM register that can contain a unique identification code, if purchased from
Dallas Semiconductor. This ID number is programmed by Dallas Semiconductor, is unchangeable, and is
unique to each customer. This ID number may be used to ensure that batteries containing a DS2435 have
the same manufacturer ID number as a charger configured to operate with that battery pack. This feature
may be used to prevent charging of batteries for which the charging circuit has not been designed.
CYCLE COUNTER (82h and 83h)
The cycle counter register gives an indication of the number of charge/discharge cycles the battery pack
has been through. This nonvolatile (E2) register is incremented by the user through the use of a protocol
to the DS2435, and is reset by another protocol. The counter is a straight binary counter, formatted as
follows:
