Pin Descriptions (Cont.)
Lattice Semiconductor
Number
1. [IN1...IN4] are inputs to the PLD. The thresholds for these pins are referenced by the voltage on VCCINP. Unused INx inputs should be tied
2. IN1 pin can also be controlled through JTAG interface.
3. [IN2..IN4] can also be controlled through I
4. GNDA and GNDD pins must be connected together on the circuit board.
5. VCCD and VCCA pins must be connected together on the circuit board.
6. Open-drain outputs require an external pull-up resistor to a supply.
7. The RESETb pin should only be used for cascading two or more ispPAC-POWR1014/A devices.
8. These pins should be connected to GNDD (ispPAC-POWR1014 only).
9. The VCCPROG pin MUST be left floating when V
10. SCL should be tied high and SDA is don’t care when I
