14 / 64 page 14 Altera Corporation MAX 7000A Programmable Logic Device Data Sheet Figure 6. I/O Control Block of MAX 7000A Devices When the tri-state buffer control is connected to ground, the output is tri-stated (high impedance) and the I/O pin can be used as a dedicated input. When the tri-state buffer control is connected to VCC, the output is enabled. The MAX 7000A architecture provides dual I/O feedback, in which macrocell and pin feedbacks are independent. When an I/O pin is configured as an input, the associated macrocell can be used for buried logic. From Macrocell Fast Input to Macrocell Register Slew-Rate Control To PIA To Other I/O Pins 6 or 10 Global Output Enable Signals (1) PIA VCC Open-Drain Output OE Select Multiplexer GND Note: (1) EPM7032AE, EPM7064AE, EPM7128A, EPM7128AE, EPM7256A, and EPM7256AE devices have six output enable signals. EPM7512AE devices have 10 output enable signals. |
