NOTES
1.
ICC under reset is measured with all output pins disconnected; XTAL1 driven with TCLCH, TCHCL = 5 ns (see Figure 17.), VIL = VSS + 0.5 V, VIH = VCC - 0.5V; XTAL2 N.C.; EA = RST = Port 0 = VCC. ICC would be slightly higher if a crystal oscillator used..
2.
Idle ICC is measured with all output pins disconnected; XTAL1 driven with TCLCH,TCHCL = 5 ns, VIL =VSS + 0.5 V, VIH =VCC - 0.5 V; XTAL2
N.C; Port 0 = VCC; EA = RST = VSS (see Figure 15.).
3.
Power Down ICC is measured with all output pins disconnected; EA = VSS, PORT 0 = VCC; XTAL2 NC.; RST = VSS (see Figure 16.).
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.
Typicals 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 IOL 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
If IOL exceeds the test condition, VOL may exceed the related specication. Pins are not guaranteed to sink current greater than the listed test conditions.
7.
For other values, please contact your sales ofce.
8.
Operating ICC is measured with all output pins disconnected; XTAL1 driven with TCLCH, TCHCL = 5 ns (see Figure 17.), VIL = VSS + 0.5 V,
VIH =VCC - 0.5V; XTAL2 N.C.; EA = Port 0 = VCC; RST = VSS. The internal ROM runs the code 80 FE (label: SJMP label). ICC would be slightly
higher if a crystal oscillator is used. Measurements are made with OTP products when possible, which is the worst case.
