95 / 107 page  95/107 ST72E331 ST72T331 7.5 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. Symbol Parameter Test Conditions Value Unit Min. Typ. Max.
