9 / 20 page 9 80C32E 4149M–AERO–06/03 DC Parameters Notes: 1. I CC under reset is measured with all output pins disconnected; XTAL1 driven with TCLCH, TCHCL = 5 ns (see Figure 6), VIL = VSS + 0.5V, V IH = VCC - 0.5V; XTAL2 N.C.; EA = RST = Port 0 = VCC. ICC would be slightly higher if a crystal oscillator is used. 2. Idle I CC is measured with all output pins disconnected; XTAL1 driven with TCLCH, TCHCL = 5 ns, VIL = VSS + 0.5V, VIH = VCC - 0.5V; XTAL2 N.C; Port 0 = VCC; EA = RST = VSS (see Figure 4). 3. Power-down I CC is measured with all output pins disconnected; EA = VSS, PORT 0 = VCC; XTAL2 NC.; RST = VSS (see Fig- ure 5). 4. Capacitance loading on Ports 0 and 2 may cause spurious noise pulses to be superimposed on the VOLs of ALE and Ports 1 and 3. The noise is due to external bus capacitance discharging into the Port 0 and Port 2 pins when these pins make 1 to 0 transitions during bus operation. In the worst cases (capacitive loading 100 pF), the noise pulse on the ALE line may exceed 0.45V with maxi VOL peak 0.6V. The use of a Schmitt Trigger is not necessary. 5. Under steady state (non-transient) conditions, I OL must be externally limited as follows: Maximum I OL per port pin: 10 mA Maximum IOL per 8-bit port: Port 0: 26 mA Ports 1, 2 and 3: 15 mA Maximum total IOL for all output pins: 71 mA Table 3. DC Parameters in Standard VoltageTA = -55 °C to +125°C; V SS = 0V; VCC = 5V ± 10%; F = 0 to 30 MHz. Symbol Parameter Min.
