DS1616
MEMORY
The memory map in Figure 2a shows the general organization of the DS1616. As can be seen in the
figure, the device is segmented into 32-byte pages. Pages 0 and 1 contain the Real Time Clock and
Control registers (see Figure 2b for more detail). The User NV RAM resides in page 2. Pages 17 to 19
are assigned to storing the alarm time stamps and durations and pages 64 to 71 are reserved for histogram
memory. The data logging memory covers pages 128 to 191. Memory pages 3 to 16, 20 to 63, 68 to 127,
and 192 and up are reserved for future extensions.
The end user can write only to the Real Time Clock and Control registers and the User NV RAM. The
rest of the memory map is read-only from the end user’s perspective.
