Evaluation Board
When E2 is closed, the AT49BV1604 (MN7) is selected by NCS0.
When E3 is closed, the AT49BV1604 (MN7) is selected by NCS2.
When E4 is closed, the AT49BV8011 (MN2) is selected by NCS0.
When E5 is closed, the AT49BV8011 (MN2) is selected by NCS3.
The two 1MB SRAM banks are connected to active high or low chip select lines 4 and 5.
E6 connects the active low NCS4 line to the first SRAM bank.
E7 connects the active high CS4 line to the first SRAM bank.
E8 connects the active low NCS5 line to the second SRAM bank.
E9 connects the active high CS5 to the second SRAM bank.
The E1 link connects the AT49BV8011 (MN2) Ready/Busy signal to the line MCKO sig-
nal of the EBI extension slot. If the Ready/Busy feature is not used, it is strongly
recommended that you open the E1 link.
The use of the Ready/Busy signal requires the MCKO signal, multiplexed with a PIO sig-
nal on the MCU to be configured in PIO input mode. This capability is, however, not
available on the EB55.
The links E3, E5, E7 and E9 are closed by default.
See Figure 2-2.
Solder the connector on the evaluation board.
Connect the plug on the EBI extension slot into the socket on the MEC01 AT91 evalua-
tion board.
Match pin 1 on the MEC01 to the square connector located on the MN1 side of the J1
connector.
Pin 1 of the EBI extension slot is marked on the board.
