Notes: 1. When 4.0 V

≤ AV

CC ≤ 5.5 V

2. When 2.7 V

≤ AV

CC < 4.0 V (mask ROM version) or when 3.0 V ≤ AVCC < 4.0 V (F-ZTAT

version)

3. When conversion time

≥ 11. 17 µs (CKS = 1 and φ ≤ 12 MHz, or CKS = 0)

4. When conversion time < 11. 17 µs (CKS = 1 and

φ > 12 MHz)

5. In single mode and

φ = maximum operating frequency.
