Table 25.6 shows bus timing.
Table 25.6 Bus Timing
Conditions: VCC = 5.0 V ±0.5 V, AVCC = 5.0 V ±0.5 V, VSS = PLLVSS = AVSS = 0 V, Ta = –20°C to
+75°C (Standard product)* 1, Ta = –40°C to +85°C (Wide temperature-range
product)*1.

Notes: 1. See page 2 for correspondence of the standard product, wide temperature-range
product, and product model name.
2. n is the number of wait cycles.
3. At the CS assert period extension, t × (3 + n) - 35.
CYC
4. At the CS assert period extension, tCYC.
5. At the CS assert period extension, 5 + tCYC.
