(1) Clock Timing

Table 27.17 lists the clock timing.

Table 27.17 Clock Timing

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 = 32.768 kHz,

2 to 16.0 MHz, Ta = –20°C to +75°C (regular

specifications)

Condition B (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 = 32.768 kHz,

2 to 6.25 MHz, Ta = –20°C to +75°C (regular

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

specifications)

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

VCC = 3.0 V to 3.6 V, AVCC = 3.0 V to 3.6 V,

Vref = 3.0 V to AVCC, VSS = AVSS = 0 V, φ = 32.768 kHz,

10.0 to 20.0 MHz, Ta = –20°C to +75°C (regular

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

specifications)
