MEMORY
The memory map of the DS2422 is shown in Figure 7. The 512 bytes general-purpose SRAM are located in pages
0 through 15. The various registers to set up and control the device fill page 16 and 17, called Register Pages 1
and 2 (details in Figure 8). Pages 18 and 19 provide storage space for calibration data. They can alternatively be
used as extension of the general-purpose memory. The Trim Register Page holds registers that are used to tune
the timing of the serial data interface and to trim the on-chip temperature converter. The "datalog" logging memory
starts at address 1000h (page 128) and extends over 256 pages. The memory pages 20 to 31 and 33 to 127
are
reserved for future extensions. The scratchpad is an additional page that acts as a buffer when writing to the SRAM
memory or the register page. The data- and calibration memory can be written at any time. The access type for the
two register pages and the Trim Register Page is register-specific and depends on whether the device is pro-
grammed for a mission. Figures 8A and 8B show
the details. The datalog memory is read-only for the user. It is
written solely under supervision 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 all the
register pages and the calibration memory. See section
Address Register and Transfer Status
for details.
