Table 20.8 DMAC Timing
Case A: V_CC = 3.0 to 5.5 V, AV_CC = 3.0 to 5.5 V, AV_CC = V_CC ±10%, AV_ref = 3.0 V to AV_CC,
V_SS = AV_SS = 0 V, Ta = –20 to +75°C*
Case B: V_CC = 5.0 V ±10%, AV_CC = 5.0 V ±10%, AV_CC = V_CC ±10%, AV_ref = 4.5 V to AV_CC,
V_SS = AV_SS = 0 V, Ta = –20 to +75°C*
Note: * Regular-specification products; for wide-temperature-range products, Ta = –40 to +85°C
