HY62WT08081E Series
Notes(WRITE CYCLE):
1. A write occurs during the overlap of a low /CS and a low /WE. A write begins at the latest transition
among /CS going low and /WE going low: A write ends at the earliest transition among /CS going high
and /WE going high. t
WP
is measured from the beginning of write to the end of write.
2. t
CW
is measured from the later of /CS going low to the end of write .
3. t
AS
is measured from the address valid to the beginning of write.
4. t
WR
is measured from the end of write to the address change. t
WR is
applied in case a write ends as /CS,
or /WE going high.
5. If /OE and /WE are in the read mode during this period, and the I/O pins are in the output low-Z state,
input of opposite phase of the output must not be applied because bus contention can occur.
6. If /CS goes low simultaneously with /WE going low, or after /WE going low, the outputs remain in high
impedance state.
7. D
OUT
is the same phase of the latest written data in this write cycle.
8. D
OUT
is the read data of the new address.
