M69KB096AA

Table 18. Synchronous Burst Write AC Characteristics

Note: 1. When configured in Synchronous mode (BCR15 = 0), a refresh opportunity must be provided every tELEH. A refresh opportunity is

satisfied by either of the following two conditions: E = VIH during Clock input K rising edge or E = VIH for longer than 15ns.

2. Clock rates lower than 50MHz (clock period higher than 20ns) are allowed as long as tELKH specifications are met.
