7.3 DC ELECTRICAL CHARACTERISTICS

(TA = -40°C to +125°C and VDD = 5V unless otherwise specified)

Notes:

1. Hysteresis voltage between switching levels. Based on characterisation results, not tested.

2. CPU running with memory access, no DC load or activity on I/O’s; clock input (OSCIN) driven by external square wave.

3. No DC load or activity on I/O’s; clock input (OSCIN) driven by external square wave.

4. Except OSCIN and OSCOUT

5. WAIT Mode with SLOW Mode selected. Based on characterisation results, not tested.
