112 / 148 page ![]() Intel® IXP45X and Intel® IXP46X Product Line of Network Processors—Datasheet Intel® IXP45X and Intel® IXP46X Product Line of Network Processors Datasheet August 2006 112 Document Number: 306261-004US 5.5.11 UART DC Parameters 5.5.12 Serial Peripheral Interface DC parameters 5.5.13 I2C Interface DC Parameters Table 40. UART DC Parameters Symbol Parameter Conditions Min. Typ. Max. Units Notes VIH Input-high voltage 2.0 V VIL Input-low voltage 0.8 V VOH Output-high voltage IOUT = - 4mA 2.4 V VOL Output-low voltage IOUT = 4mA 0.4 V IIL Input-leakage current 0 < VIN < VCCP -10 10 µA CIN Input-pin capacitance 5 pF 1 Notes: 1. These values are typical values seen by the manufacturing process and are not tested. 2. This interface has been designed assuming a single load which can be between 5pF to 25pF. Table 41. Serial Peripheral Interface DC Parameters Symbol Parameter Conditions Min. Typ. Max. Units Notes VIH Input-high voltage 2.0 V VIL Input-low voltage 0.8 V VOH Output-high voltage IOUT = - 6mA 2.4 V VOL Output-low voltage IOUT = 6mA 0.4 V IIL Input-leakage current 0 < VIN < VCCP -10 10 µA CIN Input-pin capacitance 5 pF 1 Notes: 1. These values are typical values seen by the manufacturing process and are not tested. Table 42. I2C Interface DC Parameters Symbol Parameter Conditions Min. Typ. Max. Units Notes VIH Input-high voltage 2.0 V VIL Input-low voltage 0.8 V VOH Output-high voltage IOUT = n/a n/a n/a n/a V 2 VOL Output-low voltage IOUT = 4mA 0.4 V IIL Input-leakage current 0 < VIN < VCCP -10 10 µA CIN Input-pin capacitance 5 pF 1 Notes: 1. These values are typical values seen by the manufacturing process and are not tested. 2. Voltage output high for this interface is not applicable due to it being an open drain I/O. |
