Notes:
1. Operating ICC is measured with all output pins disconnected; XTAL1 driven with
VIH = VCC - 0.5V; XTAL2 N.C.; EA = RST = Port 0 = VCC. ICC would be slightly higher
if a crystal oscillator used (see Figure 50.).
2. Idle ICC 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
3. Power-down ICC is measured with all output pins disconnected; EA = VCC, PORT 0 =
and the POF flag must be set.
4. Capacitance loading on Ports 0 and 2 may cause spurious noise pulses to be super-
imposed 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 val-
ues listed are at room temperature.
6. Under steady state (non-transient) conditions, IOL must be externally limited as fol-
lows:
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 specification. Pins are
not guaranteed to sink current greater than the listed test conditions.
7. ICC_FLASH_WRITE operating current while a Flash block write is on going.
