8 mb85344c-60/MB85344C-70 notes: 1. an initial pause (ras =cas =v ih ) of 200 m s is required after power-up followed by any eight ras -only cycles or eight cas -before-ras refresh cycles (we =v ih ) before proper device operation is achieved. if an internal refresh counter is used, a minimum of eight cas -before-ras initialization cycles are required instead of eight ras cycles. 2. ac characteristics assume t t = 2 ns. 3. v ih (min.) and v il (max.) are reference levels for measuring the timing of input signals. transition times are measured between v ih (min.) and v il (max.). 4. assumes that t rcd t rcd (max.), t rad t rad (max.). if t rcd and/or t rad is greater than the maximum recommended value shown in this table, t rac will be increased by the amount that t rcd exceeds the value shown. 5. if t rcd 3 t rcd (max.), t rad 3 t rad (max.), and t asc 3 t aa ?t cac ?t t , access time is t cac . 6. if t rad 3 t rad (max.) and t asc t aa ?t cac ?t t , access time is t aa . 7. measured with a load equivalent to two ttl loads and 100 pf. 8. t off and t ofr are specified that output buffer change to high impedance state. 9. operation within the t rcd (max.) limit ensures that t rac (max.) can be met. t rcd (max.) is speci?d as a reference point only; if t rcd is greater than the speci?d t rcd (max.) limit, access time is controlled exclusively by t cac or t aa . 10. t rcd (min.) = t rah (min.)+ 2 t t + t asc (min.). 11. operation within the t rad (max.) limit ensures that t rac (max.) can be met. t rad (max.) is speci?d as a reference point only; if t rad is greater than the speci?d t rad (max.) limit, access time is controlled exclusively by t cac or t aa . 12. either t rrh or t rch must be satis?d for a read cycle. 13. t wcs is speci?d as a reference point only. if t wcs 3 t wcs wcs (min.) the data output pin will remain high- z state through entire cycle. 14. t cpa is access time from the selection of a new column address (caused by changing cas from ??to ??. therefore, if t cp become long, t cpa also become longer than t cpa (max.). 15. assumes that cas -before-ras refresh cycle. 16. assumes that cas -before-ras self refresh cycle. 17. assumes test mode function. *source: see mb814405c data sheet for details on the electricals.
