All grounds must be electrically connected at the board level. However, for the purposes of I/O current loading, grounds are associated with the bank shown. 2. Internal GNDs and I/O GNDs (Bank 0/1) are connected inside package. 3. VCCO balls connect to two power planes within the package, one for VCCO0 and one for VCCO1. 4. Pin orientation follows the conventional order from pin 1 marking of the top side view and counter-clockwise. 5. ispMACH 4384V/B/C pin 46 is tied to GND (Bank 0). 6. ispMACH 4128V only. 7. Pin orientation A1 starts from the upper left corner of the top side view with alphabetical order ascending vertically and numerical order ascending horizontally. 8. ispMACH 4128Z and 4256Z only. NC for ispMACH 4064Z. 9. Use 256 ftBGA package for all new designs. Refer to PCN#14A-07 for 256 fpBGA package discontinuance. |
