Conditions (regular specifications):
VCC = 4.5 V to 5.5 V, PVCC = 4.5 V to 5.5 V,
AVCC = 4.5 V to 5.5 V, AVrefh = 4.5 V to AVCC,
VSS = PLLVSS = AVSS = AVrefh = 0 V,
Ta = –40°C to +85°C
Conditions (wide-range specifications): VCC = 3.0 V to 3.6 V, PVCC = 4.5 V to 5.5 V,
AVCC = 4.5 V to 5.5 V, AVrefh = 4.5 V to AVCC,
VSS = PLLVSS = AVSS = AVrefh = 0 V,
Ta = –40°C to +125°C

Notes: 1. The RES, MRES, NMI, BREQ, and IRQ3 to IRQ0 signals are asynchronous signals.
When the setup time is satisfied, change of signal level is detected at the rising edge of
the clock. If not, the detection is delayed until the rising edge of the clock.
2. In standby mode, tRESW = tOSC2 (10 ms).
3. In standby mode, t = t (10 ms).

4. tBcyc indicates external bus clock cycle time (Bφ = CK).
