DS2406

MEMORY MAP

The DS2406 has two memory sections, called data memory and status memory. The data memory

consists of 1024 bits of one-time programmable EPROM organized as 4 pages of 32 bytes each. The

address range of the device’s status memory is 8 bytes. The first seven bytes of status memory (addresses

0 to 6) are implemented as EPROM. The eighth byte (address 7) consists of static RAM. The complete

memory map is shown in Figure 5. The 8-bit scratchpad is an additional register that acts as a buffer when

writing the memory. Data is first written to the scratchpad and then verified by reading a 16-bit CRC

from the DS2406 that confirms proper receipt of the data and address. This process ensures data integrity

when programming the memory. If the buffer contents are correct, the bus master should transmit a

programming pulse (EPROM) or a dummy byte FFh (RAM) to transfer the data from the scratchpad to

the addressed memory location. The details for reading and programming the DS2406 are given in the

Memory Function Commands section.
