43 / 151 page ![]() MPC8548E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 9 Freescale Semiconductor 43 Local Bus 10 Local Bus This section describes the DC and AC electrical specifications for the local bus interface of the device. 10.1 Local Bus DC Electrical Characteristics This table provides the DC electrical characteristics for the local bus interface operating at BVDD = 3.3 V DC. Table 39 provides the DC electrical characteristics for the local bus interface operating at BVDD = 2.5 V DC. Table 38. Local Bus DC Electrical Characteristics (3.3 V DC) Parameter Symbol Min Max Unit High-level input voltage VIH 2BVDD + 0.3 V Low-level input voltage VIL –0.3 0.8 V Input current (VIN 1 = 0 V or V IN = BVDD)IIN —±5 A High-level output voltage (BVDD = min, IOH = –2 mA) VOH 2.4 — V Low-level output voltage (BVDD = min, IOL = 2mA) VOL —0.4 V Note: 1. Note that the symbol VIN, in this case, represents the BVIN symbol referenced in Table 1 and Table 2. Table 39. Local Bus DC Electrical Characteristics (2.5 V DC) Parameter Symbol Min Max Unit High-level input voltage VIH 1.70 BVDD + 0.3 V Low-level input voltage VIL –0.3 0.7 V Input current (VIN 1 = 0 V or V IN = BVDD)IIH —10 A IIL –15 High-level output voltage (BVDD = min, IOH = –1 mA) VOH 2.0 — V Low-level output voltage (BVDD = min, IOL = 1mA) VOL —0.4 V Note: 1. Note that the symbol VIN, in this case, represents the BVIN symbol referenced in Table 1 and Table 2. |
