Figure 15. Crystal oscillator and resonator connection scheme VIH SR P Input high level CMOS (Schmitt Trigger) Oscillator bypass mode 0.65VDD —VDD+0.4 V VIL SR P Input low level CMOS (Schmitt Trigger) Oscillator bypass mode 0.4 — 0.35VDD V 1. VDD = 3.3 V ± 10% / 5.0 V ± 10%, TA = 40 to 125 °C, unless otherwise specified 2. Stated values take into account only analog module consumption but not the digital contributor (clock tree and enabled peripherals) Table 38. Fast external crystal oscillator (4 to 16 MHz) electrical characteristics (continued) Symbol C Parameter Conditions(1) Value Unit Min Typ Max OSC32K_XTAL OSC32K_EXTAL DEVICE C2 C1 OSC32K_XTAL OSC32K_EXTAL DEVICE Note: OSC32K_XTAL/OSC32K_EXTAL must not be directly used to drive external circuits. |
