Notes :
1) Capacitive loading on ports 0 and 2 may cause spurious noise pulses to be superimposed on the V_OL of ALE
and port 1, 3, 4, 5, 6, and 9. 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 case (capacitive loading
> 100 pF), the noise pulse on ALE line may exceed 0.8 V. In such cases it may be desirable to qualify ALE
with a schmitt-trigger, or use an address latch with a schmitt-trigger strobe input.
2) Capacitive loading on ports 0 and 2 may cause the V_OH on ALE and PSEN/RDF to momentarily fall below the
0.9 V_CC specification when the address lines are stabilizing.
3) I_PD (power down mode) is measured under following conditions:
EA = RESET = V_CC; Port0 = Port7 = Port8 = V_CC; XTAL1 = N.C.; XTAL2 = V_SS; PE/SWD = OWE = V_SS;
HWDP = V_CC; V_AREF = V_CC; V_AGND = V_SS; all other pins are disconnected.
Hardware power down mode current (I_PD) is measured with OWE =V_CC or V_SS.
4) I_CC (active mode) is measured with:
XTAL2 driven with t_R/t_F = 5 ns , V_IL = V_SS + 0.5 V, V_IH = V_CC – 0.5 V; XTAL1 = N.C.; EA = PE/SWD= V_CC ;
Port0 = Port7 = Port8 = V_CC ; HWPD = V_CC ; RESET = V_SS; all other pins are disconnected. I_CC would be
slightly higher if a crystal oscillator is used.
5) I_CC (idle mode) is measured with all output pins disconnected and with all peripherals disabled;
XTAL2 driven with t_R/t_F = 5 ns, V_IL = V_SS + 0.5 V, V_IH = V_CC – 0.5 V; XTAL1 = N.C.; RESET = V_CC;
HWPD = V_CC ; Port0 = Port7 = Port8 = V_CC ; EA = PE/SWD = V_SS; all other pins are disconnected;
6) Input leakage current for port 0 is measured with RESET = V_CC.
7) Overload conditions occur if the standard operating conditions are exeeded, ie. the voltage on any pin exceeds
the specified range (i.e. V_OV > V_CC + 0.5 V or V_OV < V_SS - 0.5 V). The supply voltage V_CC and V_SS must remain
within the specified limits. The absolute sum of input currents on all port pins may not exceed 50 mA.
8) Not 100% tested, guaranteed by design characterization.
9) The typical I_CC values are periodically measured at T_A = +25 ˚C and V_CC = 5 V but not 100% tested.
10)The maximum I_CC values are measured under worst case conditions (T_A = 0 ˚C or -40 ˚C and V_CC = 5.5 V)
