Pin Descriptions (Cont.)
Lattice Semiconductor
1. GND pins must be connected together on the circuit board.
2. Open-drain outputs require an external pull-up resistor to a supply.
3. IN1_PWRDN and IN2 are inputs to the PLD. The thresholds for these pins are referenced by the voltage on VCC.
4. The power-down function is E
5. Source of the power-down initiation can be assigned to either the IN1_PWRDN pin or to an internally generated PLD output signal called
6. VCC pins must be connected together on the circuit board.
7. In power-down mode, VCCJ is internally pulled to GND to turn off the JTAG I/O pins. It is important, therefore, that the VCCJ pin be open
8. The VMON inputs can be biased independently from VCC. Unused VMON inputs should be tied to GND.
9. Thresholds of IN_OUT3...IN_OUT7 in the input mode are referenced by the voltage on VCC.

PLD_PWRDN. When generated internally by the PLD, the IN1_PWRDN pin is only used to exit power-down mode (IN1_PWRDN pin =
high).
whenever power-down mode is initiated. If connected to a power supply during power-down mode, VCCJ will draw approximately 2.2mA.
