PC CARD PIN ASSIGNMENTS

Notes:

I = Input to card, O = Output from card

I/O = Bidirectional

NC = No connect

In systems which switch VCC individually to cards, no signal should be directly connected between cards other than ground.

1. VPP not required for Programming or Reading operations.

2. BVD = Internally pulled-up.

3. Signal must not be connected between cards.

4. Highest address bit for 1 Mbyte card.

5. Highest address bit for 2 Mbyte card.

6. Highest address bit for 4 Mbyte card.

7. Highest address bit for 10 Mbyte card.
