Pin Capacitance

CIN

Input Pin Capacitance

FC = 1 MHz (Notes 6 & 10)

I/O or Output Pin Capacitance

FC = 1 MHz (Note 6)

CCLK

CLK Pin Capacitance

FC = 1 MHz (Note 6)

Notes:

1. IOL1 applies to AD[31:00], C/BE[3:0], REQ, and PAR

IOL2 applies to FRAME, IRDY, TRDY, DEVSEL, STOP, SERR, PERR, and LOCK

IOL3 applies to EESK/LED1, EEDO/LED3, and EEDI/LNKST

2. VOH does not apply to open–drain output pins.

3. IIL and IIH apply to all input pins except XTAL1.

4. IOZL and IOZH apply to all three-state output pins and bi-directional pins.

5. Outputs are CMOS and will be driven to rail if the load is not resistive.

6. Parameter not tested. Value determined by characterization.

7. Tested, but to values in excess of limits. Test accuracy not sufficient to allow screening guard bands.

8. Correlated to other tested parameters – not tested directly.

9. Test not implemented to data sheet specification.

10. CIN = 8 pF for IDSEL input.
