DC Parameters for Standard Voltage (2)
TA = 0
°C to +70°C; V
SS = 0 V; VCC = 2.7V to 5.5V; F = 10 to 40 MHz
TA = -40
°C to +85°C; V
SS = 0 V; VCC = 2.7V to 5.5V; F = 10 to 40 MHz
Notes:
1. Operating I
CC is measured with all output pins disconnected; XTAL1 driven with TCLCH, TCHCL = 5 ns (see Figure 17-4.),
V
IL = VSS + 0.5V,
VIH = VCC - 0.5V; XTAL2 N.C.; EA = RST = Port 0 = VCC. ICC would be slightly higher if a crystal oscillator used (see Figure
17-1).
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 17-2).
3. Power-down I
CC is measured with all output pins disconnected; EA = VSS, PORT 0 = VCC; XTAL2 NC.; RST = VSS (see Figure
17-3).
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 100pF), the noise pulse on the ALE line may exceed
0.45V with maxi VOL peak 0.6V. A Schmitt Trigger use is not necessary.
5. Typical are based on a limited number of samples and are not guaranteed. The values listed are at room temperature and
5V.
6. Under steady state (non-transient) conditions, IOL must be externally limited as follows:
Maximum I
OL per port pin: 10 mA
Maximum I
OL per 8-bit port:
Port 0: 26 mA
Ports 1, 2 and 3: 15 mA
Maximum total IOL for all output pins: 71 mA
If IOL exceeds the test condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater
than the listed test conditions.
