Table 12: RAM Cell Synchronous Write Timing
Parameter: RAM Cell Synchronous Write Timing
WA setup time to WCLK: the amount of time the Write ADDRESS must be stable
before the active edge of the Write CLOCK
WA hold time to WCLK: the amount of time the Write ADDRESS must be stable
after the active edge of the Write CLOCK
WD setup time to WCLK: the amount of time the Write DATA must be stable before
the active edge of the Write CLOCK
WD hold time to WCLK: the amount of time the Write DATA must be stable after
the active edge of the Write CLOCK
WE setup time to WCLK: the amount of time the Write ENABLE must be stable
before the active edge of the Write CLOCK
WE hold time to WCLK: the amount of time the Write ENABLE must be stable after
the active edge of the Write CLOCK
WCLK to RD (WA=RA): the amount of time between the active Write CLOCK edge
and the moment when the data is available at RD
