27 / 40 page SN74V215, SN74V225, SN74V235, SN74V245 512 × 18, 1024 × 18, 2048 × 18, 4096 × 18 DSP-SYNC FIRST-IN, FIRST-OUT MEMORIES SCAS636E – APRIL 2000 – REVISED SEPTEMBER 2002 27 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 WCLK WEN tCLKH tCLKL tENH tENS PAF tPAFS RCLK REN tENH tENS tPAFS D – (m + 1) Words in FIFO D – m Words in FIFO D – (m + 1) Words in FIFO tSKEW2 (see Note C) NOTES: A. m = PAF offset B. D = maximum FIFO depth In FWFT mode: D = 513 for the SN74V215, 1025 for the SN74V225, 2049 for the SN74V235, and 4097 for the SN74V245. In standard mode: D = 512 for the SN74V215, 1024 for the SN74V225, 2048 for the SN74V235, and 4096 for the SN74V245. C. tSKEW2 is the minimum time between a rising RCLK edge and a rising WCLK edge for PAF to go high during the current clock cycle. If the time between the rising edge of RCLK and the rising edge of WCLK is less than tSKEW2, the PAF deassertion time might be delayed an extra WCLK cycle. D. PAF is asserted and updated on the rising edge of WCLK only. E. Select synchronous modes by setting (FL, RXI, WXI) = (1,0,0), (1,0,1), or (1,1,0) during reset. Figure 19.
