Hardware Specification Revision 1.3
6.3. Memory Map
The memory map has been configured to make the SRAM supporting the S-7600A compact. S-7600A
has two 5 K byte memory banks (denoted as “0” and “1”). Their mapping addresses are given in Table
6-1 and Table 6-2.
The actual capacity of the incoming buffer is 2047 bytes.
The actual capacity of the outgoing buffer is 1023 bytes for TCP mode and 1015 bytes for UDP mode.
