34 / 124 page  MPC8377E PowerQUICC™ II Pro Processor Hardware Specifications, Rev. 2 34 Freescale Semiconductor Local Bus 10.1 Local Bus DC Electrical Characteristics Table 35 and Table 36 provides the DC electrical characteristics for the local bus interface. Table 35. Local Bus DC Electrical Characteristics (LBVDD =3.3 V) At recommended operating conditions with LBVDD = 3.3 V. Parameter Conditions Symbol Min Max Unit Supply voltage 3.3 V — LBVDD 3.135 3.465 V Output high voltage IOH = –4.0 mA LBVDD = Min VOH 2.40 — V Output low voltage IOL = 4.0 mA LBVDD = Min VOL —0.50 V Input high voltage — — VIH 2.0 LBVDD + 0.3 V Input low voltage — — VIL –0.3 0.90 V Input high current VIN 1 = LBV DD IIH —30 μA Input low current VIN 1 = GND IIL –30 — μA Table 36. Local Bus DC Electrical Characteristics (LBVDD =2.5 V) At recommended operating conditions with LBVDD = 2.5 V. Parameter Conditions Symbol Min Max Unit Supply voltage 2.5 V — LBVDD 2.37 2.73 V Output high voltage IOH = –1.0 mA LBVDD = Min VOH 2.00 — V Output low voltage IOL = 1.0 mA LBVDD = Min VOL —0.40 V Input high voltage — LBVDD = Min VIH 1.7 LBVDD + 0.3 V Input low voltage — LBVDD = Min VIL –0.3 0.70 V Input high current VIN 1 = LBV DD IIH —20 μA Input low current VIN 1 = GND IIL –20 — μA Table 37. Local Bus DC Electrical Characteristics (LBVDD =1.8 V) At recommended operating conditions with LBVDD = 1.8 V. Parameter Conditions Symbol Min Max Unit Supply voltage 1.8 V — LBVDD 1.71 1.89 V Output high voltage IOH = –1.0 mA LBVDD = Min VOH LBVDD – 0.45 — V Output low voltage IOL = 1.0 mA LBVDD = Min VOL —0.45 V Input high voltage — LBVDD = Min VIH 0.65 × LBVDD LBVDD + 0.3 V Input low voltage — LBVDD = Min VIL –0.3 0.35 × LBVDD V Input high current VIN 1 = LBV DD IIH —10 μA Input low current VIN 1 = GND IIL –10 — μA |
