AC Timing for SIU Inputs No. Characteristic Value2 Units 10 Hold time for all signals after the 50% level of the DLLIN rising edge 0.5 ns 11a ABB/AACK set-up time before the 50% level of the DLLIN rising edge 3.5 ns 11b DBG/DBB/BR/TC set-up time before the 50% level of the DLLIN rising edge 5.0 ns 11c ARTRY set-up time before the 50% level of the DLLIN rising edge 4.0 ns 11d TA set-up time before the 50% level of the DLLIN rising edge • Pipeline mode • Non-pipeline mode 3.5 4.0 ns ns 11e TEA set-up time before the 50% level of the DLLIN rising edge • Pipeline mode • Non-pipeline mode 4.0 3.0 ns ns 11f PSDVAL set-up time before the 50% level of the DLLIN rising edge • Pipeline mode • Non-pipeline mode 3.5 3.5 ns ns 11g TS set-up time before the 50% level of the DLLIN rising edge 5.0 ns 11h BG set-up time before the 50% level of the DLLIN rising edge 4.5 ns 12 Data bus set-up time before the 50% level of the DLLIN rising edge in Normal • Pipeline mode • Non-pipeline mode 2.5 5.0 ns ns 13 Data bus set-up time before the 50% level of the DLLIN rising edge in ECC and PARITY modes • Pipeline mode • Non-pipeline mode 2.5 8.0 ns ns 14 DP set-up time before the 50% level of the DLLIN rising edge • Pipeline mode • Non-pipeline mode 4.0 9.0 ns ns 15a Address bus set-up time before the 50% level of the DLLIN rising edge • Extra cycle mode (SIUBCR[EXDD] = 0) • Non-extra cycle mode (SIUBCR[EXDD] = 1) 5.0 8.0 ns ns 15b Address attributes: TT/TBST/TSIZ/GBL set-up time before the 50% level of the DLLIN rising edge • Extra cycle mode (SIUBCR[EXDD] = 0) • Non-extra cycle mode (SIUBCR[EXDD] = 1) 5.0 5.5 ns ns 161 PUPMWAIT/IRQ signals set-up time before the 50% level of the DLLIN rising edge 3.0 ns Notes: 1. The set-up time for these signals is for synchronous operation. Any set-up time can be used for asynchronous operation. 2. Input specifications are measured from the 50% level of the rising edge of DLLIN to the 50% level of the signal. Timings are measured at the pin. |
