A/D Conversion Characteristics

Table 27.47 lists the A/D conversion characteristics.

Table 27.47 A/D Conversion Characteristics

Condition A (F-ZTAT version and masked ROM version):

VCC = 2.7 V to 3.6 V, AVCC = 2.7 V to 3.6 V,

Vref = 2.7 V to AVCC, VSS =AVSS = 0 V,

φ = 2 to 13.5 MHz,

Ta = –20°C to +75°C (regular specifications),

Ta = –40°C to +85°C (wide-range specifications)

Condition B (F-ZTAT version):

VCC = 2.2 V to 3.6 V, AVCC = 2.2 V to 3.6 V,

Vref = 2.2 V to AVCC, VSS =AVSS = 0 V,

φ = 2 to 6.25 MHz,

Ta = –20°C to +75°C (regular specifications)

Condition C (Masked ROM version): VCC = 2.2 V to 3.6 V, AVCC = 2.2 V to 3.6 V,

Vref = 2.2 V to AVCC, VSS = AVSS = 0 V,

φ = 2 to 6.25 MHz,

Ta = –20°C to +75°C (regular specifications),

Ta = –40°C to +85°C (wide-range specifications)
