32M Synchronous Burst CellularRAM
Functional Description
2.7
NOR-Flash-Type Mode
In NOR-Flash mode the CellularRAM applies the NOR-Flash protocol to perform read and write accesses to the
memory. Read accesses can be executed in synchronous burst mode, while write accesses are executed in
asynchronous mode using ADV as address latch strobe signal.
2.7.1
Synchronous Read Mode
[Disclaimer]
WAIT signal of all synchronous timings below is shown in the case of WC=0 (at delay) and WP=0 (active low) though it is not
default state.
In synchronous read mode all operations are referred to the rising or falling clock signal edge. Refresh cycles or
page boundary crossings are indicated by the WAIT output signal which stalls the processor for this period.
