DS1922E
iButton High-Temperature Logger with
8KB Data-Log Memory
Memory
Figure 5 shows the DS1922E memory map. Pages 0 to
15 contain 512 bytes of general-purpose SRAM. The
various registers to set up and control the device fill
pages 16 and 17, called register pages 1 and 2 (see
Figure 6 for details). Pages 18 and 19 can be used as
extension of the general-purpose memory. The data-log
logging memory starts at address 1000h (page 128)
and extends over 256 pages. The memory pages 20 to
127 are reserved for future extensions. The scratchpad
is an additional page that acts as a buffer when writing
memory can be written at any time. The access type for
the register pages is register-specific and depends on
whether the device is programmed for a mission.
Figure 6 shows the details. The data-log memory is
read only for the user. It is written solely under supervi-
sion of the on-chip control logic. Due to the special
behavior of the write access logic (write scratchpad,
copy scratchpad), it is recommended to only write full
pages at a time. This also applies to the register pages.
See the Address Registers and Transfer Status section
for details.
