1. Current products are identified by process letters “AB”.
2. New products are identified by process letter K. For these new products, the test flow guarantees the AC parameter values
defined in this table (when VCC = 1.8 V) and the AC parameter values defined in Table 17 (when VCC= 2.5 V or VCC=
5.0 V).
3. tCH + tCL must never be less than the shortest possible clock period, 1 / fC(max)
4. Value guaranteed by characterization, not 100% tested in production.
