HD64F3437TF16 Datasheet, PDF (366/752 Pages) Hitachi Semiconductor – 12 V must not be applied to the S-mask model (single-power-supply specification), as this may permanently damage the device.

15.1.3 Input Pins
Table 15.1 lists the A/D converter’s input pins. The eight analog input pins are divided into two
groups: group 0 (AN₀ to AN₃), and group 1 (AN₄ to AN₇). AV_CC and AV_SS are the power supply
for the analog circuits in the A/D converter. AV_ref is the A/D conversion reference voltage.
