(8) Serial Communication Interface Timing
Table 20.25 Serial Communication Interface Timing
Conditions: V_CC = 3.3 V ±0.3V, AV_CC = 3.3 V ±0.3V, AV_CC = V_CC ±0.3V, AV_ref = 3.0 V to
AV_CC, V_SS = AV_SS = 0 V, φ = 12.5 to 20 MHz*¹, Ta = –20 to +75°C*²
Notes: *1 ROMless products only for 20 MHz version
*2 Regular-specification products; for wide-temperature-range products, Ta = –40 to
+85°C
