Advanced Information

ABSOLUTE MAXIMUM RATINGS

Absolute Maximum Ratings are stress ratings only. Permanent damage to the device may be caused by continuously operating at

or beyond these limits. Device functional operating limits and guaranteed performance specifications are given under Electrical

Characteristics at the test conditions specified

ESD Sensitive Device. This device is manufactured on a CMOS process. It is therefore generically susceptible

to damage from excessive static voltages. Proper ESD precautions must be taken during handling and storage

of this device.

Notes:

1. Analogue and digital grounds must always be within 0.3V of each other.

2. The digital supply core voltage (DCVDD) must always be less than or equal to the analogue supply voltage (AVDD) or

digital supply buffer voltage (DBVDD).

3. The digital supply buffer voltage (DBVDD) must always be less than or equal to the analogue supply voltage (AVDD).

4. When CLKIDIV2=1
