Notes:

1. CD1# and CD2# are grounded internal to PC Card.

2. Shows density for which speciﬁed address bit is MSB. Higher order address bits are

no connects (i.e., 1MB A19 is MSB, A20 - A21 are NC).

3. BVD1 is an open drain output with a 10K ohm internal pull-up resistor.

4. Address bit 22 is used for the 8MB cards as well as the 6MB Cards.
