Notes:
1) _{Capacitive loading on ports 0 and 2 may cause spurious noise pulses to be superimposed on the VOL of ALE}
and port 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 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 VOH on ALE and PSEN to momentarily fall bellow the}
0.9 V_CC specification when the address lines are stabilizing.
3) _{IPD (Power Down Mode) is measured under following conditions:}
EA = Port0 = V_CC; RESET = V_SS; XTAL2 = N.C.; XTAL1 = V_CC; all other pins are disconnected.
4) _{ICC (active mode) is measured with:}
XTAL1 driven with t_CLCH, t_CHCL = 5 ns, V_IL = V_SS + 0.5 V, V_IH = V_CC – 0.5 V; XTAL2 = N.C.;
EA = Port0 = RESET = V_CC; all other pins are disconnected. I_CC would be slightly higher if a crystal oscillator
is used (appr. 1 mA).
5) _{ICC (Idle mode) is measured with all output pins disconnected and with all peripherals disabled;}
XTAL1 driven with t_CLCH, t_CHCL = 5 ns, V_IL = V_SS + 0.5 V, V_IH = V_CC – 0.5 V; XTAL2 = N.C.;
RESET = EA = V_SS; Port0 = V_CC; all other pins are disconnected;
6) _{ICC Max at other frequencies is given by:}
C511/C511A/C513/C513A : Active mode: TBD
Idle mode: TBD
C513A-H :
Active mode: TBD
Idle mode: TBD
where f_OSC is the oscillator frequency in MHz. I_CC values are given in mA and measured at V_CC = 5 V.
7) _{This parameter is periodically sampled and not 100% tested.}
8) _{The typical ICC values are periodically measured at TA = +25 ˚C but not 100% tested.}
