The page select bit indicates the bit at the top address. The address indicator bit is set in the 8 bits between WA7 to WA0 within the address command. However, since a total of 256 combinations are possible, for EEPROMs greater than 4kbits the address indicator bit is assigned within the Slave address. Therefore, for the page selection bit please handle the expansion of WA7-0 considering the following. BR24L04-W PS → WA8 BR24L08-W P1 → WA9 P0 → WA8 BR24L16-W P2 → WA10 P1 → WA9 P0 → WA8 (Reference) Type No. of addresses No. of required bits Indicator address Bit name BR24L02-W 256 8 WA7 to WA0 BR24L04-W 512 9 PS WA7 to WA0 BR24L08-W 1024 10 P1,P0 WA7 to WA0 BR24L16-W 2048 11 P2,P1,P0 WA7 to WA0
