Lattice Semiconductor
SRAM Interface
The LatticeXP2 Brevia Evaluation Board provides 1Mbit of asynchronous SRAM memory in a 128K x 8-bit configu-
ration.
Table 7.
Configuration Interface
Jumper 5 controls the XP2 CFG0 input control pin.
Table 8. Configuration Interface
The factory default setting on J5 is to leave it unshunted. CFG0 has a weak pullup resistor.
