It clocks at 100 MHz with an 8 ns access time, operating from a 4.5 V to 5.5 V supply. ## 100 MHz clock, 8 ns access — timing margin for the bus The 100 MHz data rate and 8 ns access time set the read-cycle timing window. ## 144K (8K x 18) depth — buffer sizing for packet or line-rate storage With 8K entries of 18 bits each, this FIFO holds 144K bits. ## Sourcing reality — obsolete, sourced to order The CY7C4255-10AC is marked obsolete.
