27.6.3 AC Characteristics

Figure 27.9 shows the test conditions for the AC characteristics.

(1) Clock Timing

Table 27.53 lists the clock timing.

Table 27.53 Clock Timing

Condition A (ZTAT 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 10 MHz,

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

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

Condition B (F-ZTAT version, 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 13.5MHz,

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

Ta = –40°C to +85°C (wide-range 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 = 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)
