40 / 82 page ![]() &3, Data Sheet 38 1999-07 Parameter Interpretation The parameters listed in the following partly represent the characteristics of the C161PI and partly its demands on the system. To aid in interpreting the parameters right, when evaluating them for a design, they are marked in column “Symbol”: CC (Controller Characteristics): The logic of the C161PI will provide signals with the respective timing characteristics. SR (System Requirement): The external system must provide signals with the respective timing characteristics to the C161PI. DC Characteristics (Standard Supply Voltage Range) (Operating Conditions apply) Parameter Symbol Limit Values Unit Test Condition min. max. Input low voltage XTAL1, P3.0, P3.1, P6.5, P6.6, P6.7 9 IL1 SR – 0.5 0.3 V DD V– Input low voltage (TTL) 9 IL SR – 0.5 0.2 9 DD – 0.1 V– Input low voltage (Special Threshold) 9 ILS SR – 0.5 2.0 V – Input high voltage RSTIN 9 IH1 SR 0.6 9 DD 9 DD + 0.5 V– Input high voltage XTAL1, P3.0, P3.1, P6.5, P6.6, P6.7 9 IH2 SR 0.7 9 DD 9 DD + 0.5 V– Input high voltage (TTL) 9 IH SR 0.2 9 DD + 0.9 9 DD + 0.5 V– Input high voltage (Special Threshold) 9 IHS SR 0.8 9 DD - 0.2 9 DD + 0.5 V– Input Hysteresis (Special Threshold) HYS 400 – mV – Output low voltage (PORT0, PORT1, Port 4, ALE, RD, WR, BHE, CLKOUT, RSTOUT) 9 OL CC – 0.45 V , OL = 2.4 mA Output low voltage (P3.0, P3.1, P6.5, P6.6, P6.7) 9 OL2 CC – 0.4 V , OL2 = 3 mA |
