Ram High
Address
Jumpers
When External Memory is enabled in an AVR, all Port C pins are by default used for the
high address byte. If the full 60 KB address space is not required to access the external
memory, some, or all, Port C pins can be released for normal port pin function as
described in the ATmega128(L) datasheet. AT90S/LS8515, ATmega103(L) and
ATmega161 do not have this feature, and all jumpers should be connected if using the
XRAM interface with these devices.
If some or all of the Port C pins are released for normal port pin functions, the corre-
sponding “ RAM High Address ” jumper should be removed to avoid any Port C activity to
reach the SRAM address pins thus corrupting the address.
If a jumper is removed, the corresponding address line will be pulled low giving a logic
2.7
A[7:0] Connector The connector marked A[7:0] contains the 8 least-significant bits of the external SRAM
address bus. The purpose of the connector is to provide easy access to the address
bus. The 8 most significant bits can be found on the “ Ram High Addresses ” jumpers or
the Port C connector.
This connector is handy when using the SRAM interface to interface external devices.

Using the SRAM
Interface with
AT90S/LS8515
and ATmega161
When using the SRAM interface with devices placed in the STK500 board, some addi-
tional straps are required. The reason is that the RD, WR, and ALE signals are not on
the same port pins for the AT90S8515/ATmega161(L) and ATmega103(L)/
ATmega128(L), so these signals must be routed manually using two of the 2-wire
cables.
