Notes:
3. X = “Don't Care.” H = Logic HIGH, L = Logic LOW.
4. WRITE = L when any one or more Byte Write enable signals and BWE = L or GW= L. WRITE = H when all Byte write enable signals , BWE, GW = H.
5. The DQ pins are controlled by the current cycle and the OE signal. OE is asynchronous and is not sampled with the clock.
6. CE
1
, CE
2
, and CE
3
are available only in the TQFP package. BGA package has only 2 chip selects CE
1
and CE
2
.
7. The SRAM always initiates a read cycle when ADSP is asserted, regardless of the state of GW, BWE, or BW
. Writes may occur only on subsequent clocks
after the ADSP or with the assertion of ADSC. As a result, OE must be driven HIGH prior to the start of the write cycle to allow the outputs to tri-state. OE is a
8. OE is asynchronous and is not sampled with the clock rise. It is masked internally during write cycles. During a read cycle all data bits are Tri-State when OE is
inactive or when the device is deselected, and all data bits behave as output when OE is active (LOW).
9. Table only lists a partial listing of the byte write combinations. Any Combination of BW
X
is valid Appropriate write will be done based on which byte write is active.
