A/D Conversion Characteristics

Notes:

Use when AVCC = VCC1.

Flash memory rewrite disabled. Except for the analog input pin, set the pins to be measured as input ports and

connect them to VSS. See Figure 5.2 “A/D Accuracy Measure Circuit”.

A/D Conversion Characteristics (1/2) (1)

VCC1 = AVCC = 3.0 to 5.5 V ≥ VCC2 ≥ VREF, VSS = AVSS = 0 V at Topr = -20°C to 85°C/-40°C to 85°C unless otherwise

specified.
