Notes
1. Pins CMDVCC, VPP21, VPP15, VPP12.5, CMD7, CMD3.5 and PRES are active LOW; pins RSTIN and PRES are
active HIGH.
2. The transition time and duty cycle definitions are shown in Fig.12;
.
3. P is the card programming voltage set by pin VPP12.5, VPP15 or VPP21.
4. The tests for dynamic response of both VPP and VCC are performed at 1 Hz, 10 kHz, 100 kHz and 1 MHz, with a
capacitive load of 100 nF.
5. This condition ensures proper starting of the oscillator with crystals having a series resistance up to 100
