4. Data labelled “Typ” is not to be used for design purposes but is intended as an indication of the IC’s potential performance.
5. The formulas given are for the typical characteristics only at 25
_C.
6. When using the on chip oscillator the total supply current (in
Adc) becomes: IT = ID + 2 Ctc VDD f x 10–3 where ID is in A, Ctc is in pF,
VDD in Volts DC, and f in kHz. (see Fig. 3) Dissipation during power–on with automatic reset enabled is typically 50 A @ VDD = 10 Vdc.
