D/A Conversion Characteristics

Table 21.10 lists the D/A conversion characteristics

Table 21.10 D/A Conversion Characteristics

Condition A: VCC = AVCC = 2.7 V to 5.5 V, Vref = 2.7 V to AVCC, VSS = AVSS = 0 V,

φ = 2 to 10 MHz, Ta = –20 to +75°C (regular specifications),

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

Condition B: VCC = AVCC = 5.0 V ±10%, Vref = 4.5 V to AVCC, VSS = AVSS = 0 V,

φ = 2 to 20 MHz, Ta = –20 to +75°C (regular specifications),

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

Usage Note

Although both the ZTAT and mask ROM versions fully meet the electrical specifications listed in

this manual, due to differences in the fabrication process, the on-chip ROM, and the layout

patterns, there will be differences in the actual values of the electrical characteristics, the operating

margins, the noise margins, and other aspects.

Therefore, if a system is evaluated using the ZTAT version, a similar evaluation should also be

performed using the mask ROM version.
