11 / 92 page  MPC885/MPC880 Hardware Specifications, Rev. 3 Freescale Semiconductor 11 DC Characteristics 6 DC Characteristics Table 6 provides the DC electrical characteristics for the MPC885/880. 2 Maximum power dissipation at V DDL = VDDSYN= 1.9 V, and VDDH is at 3.5 V. NOTE The values in Table 5 represent VDDL-based power dissipation and do not include I/O power dissipation over VDDH. I/O power dissipation varies widely by application due to buffer current, depending on external circuitry. The VDDSYN power dissipation is negligible. Table 6. DC Electrical Specifications Characteristic Symbol Min Max Unit Operating voltage VDDL (Core) 1.7 1.9 V VDDH (I/O) 3.135 3.465 V VDDSYN 1 1 The difference between V DDL and VDDSYN cannot be more than 100 mV. 1.7 1.9 V Difference between VDDL and VDDSYN — 100 mV Input high voltage (all inputs except EXTAL and EXTCLK) 2 2 The signals PA[0:15], PB[14:31], PC[4:15], PD[3:15], PE(14:31), TDI, TDO, TCK, TRST, TMS, MII1_TXEN, MII_MDIO are 5-V tolerant. The minimum voltage is still 2.0 V. VIH 2.0 3.465 V Input low voltage 3 3 V IL(max) for the I 2C interface is 0.8 V rather than the 1.5 V as specified in the I2C standard. VIL GND 0.8 V EXTAL, EXTCLK input high voltage VIHC 0.7*(VDD H) VDDH V Input leakage current, Vin = 5.5 V (except TMS, TRST, DSCK and DSDI pins) for 5-V tolerant pins 2 Iin — 100 µA Input leakage current, Vin = VDDH (except TMS, TRST, DSCK, and DSDI) IIn —10 µA Input leakage current, Vin = 0 V (except TMS, TRST, DSCK and DSDI pins) IIn —10 µA Input capacitance 4 Cin —20 pF Output high voltage, IOH = –2.0 mA, except XTAL and open-drain pins VOH 2.4 — V Output low voltage IOL = 2.0 mA (CLKOUT) IOL = 3.2 mA 5 IOL = 5.3 mA 6 IOL = 7.0 mA (TXD1/PA14, TXD2/PA12) IOL = 8.9 mA (TS, TA, TEA, BI, BB, HRESET, SRESET) VOL —0.5 V |
