32M Asynch/Page CellularRAM
Functional Description
2.4.1
If activated by RCR.Bit7 page mode allows to toggle the four lower address bits (A3 to A0) to perform subsequent
random read accesses (max. 16-words by A3 - A0) at much faster speed than 1
st
read access. Page mode
operation supports only read access in CellularRAM. As soon as page mode is activated, CS1 low time restriction
(
t
CSL
) applies. In case of CS1 staying low longer than
t
CSL
limit, then it is alternative way to toggle non-page address
(A20 - A4) no later than
t
CSL,max
. Therefore the usage of page mode is only recommended in systems which can
respect this limitation.
Please see also application note on
