Table 19. AC characteristics (M950x0-R or M95040-DF, device grade 6)(1)

1. The timing values described in this table are recommended for new designs.

Test conditions specified in Table 10 or Table 11 and Table 12(2)

2. If the application uses the M950x0-R or M95040-DF devices at 2.5 V

≤VCC ≤5.5 V and -40 °C ≤TA ≤+85 °C,

please refer to Table 18: AC characteristics (M950x0-W, device grade 6), rather than to the above table.
