Note: 1. IPD (Power-down Mode) is measured with:
XTAL1=VSS; XTAL2=not connected; RESET=VCC; Port 0 =VCC; all other pins are disconnected. PLD not in Turbo mode.
2. ICC_CPU (active mode) is measured with:
XTAL1 driven with tCLCH, tCHCL = 5ns, VIL = VSS+0.5V, VIH = Vcc – 0.5V, XTAL2 = not connected; RESET=VSS; Port 0=VCC; all
other pins are disconnected. ICC would be slightly higher if a crystal oscillator is used (approximately 1mA).
3. ICC_CPU (Idle Mode) is measured with:
XTAL1 driven with tCLCH, tCHCL = 5ns, VIL = VSS+0.5V, VIH = VCC– 0.5V, XTAL2 = not connected; Port 0 = VCC;
RESET=VCC; all other pins are disconnected.
4. PLD is in non-Turbo Mode and none of the inputs are switching.
5. See Figure 72 for the PLD current calculation.
6. I/O current = 0 mA, all I/O pins are disconnected.
