32 / 43 page Semiconductor Group 32 C511 / C513 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 VCC specification when the address lines are stabilizing. 3) IPD (Power Down Mode) is measured under following conditions: EA = Port0 = VCC; RESET = VSS; XTAL2 = N.C.; XTAL1 = VCC; all other pins are disconnected. 4) ICC (active mode) is measured with: XTAL1 driven with tCLCH, tCHCL = 5 ns, VIL = VSS + 0.5 V, VIH = VCC – 0.5 V; XTAL2 = N.C.; EA = Port0 = RESET = VCC; all other pins are disconnected. ICC 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 tCLCH, tCHCL = 5 ns, VIL = VSS + 0.5 V, VIH = VCC – 0.5 V; XTAL2 = N.C.; RESET = EA = VSS; Port0 = VCC; 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 fOSC is the oscillator frequency in MHz. ICC values are given in mA and measured at VCC = 5 V. 7) This parameter is periodically sampled and not 100% tested. 8) The typical I CC values are periodically measured at TA = +25 ˚C but not 100% tested.
