DEVICE OPERATIONS
The following operations can be performed using
the appropriate bus cycles: Address Latch, Read
Array (Random, and Page Modes), Write com-
mand, Output Disable, Standby, Reset/Power-
down and Block Locking. See Table 8.
Address Latch. In asynchronous operation, the
address is latched on the rising edge of L input; in
burst mode, the address is latched either by L go-
ing high or with a rising/falling edge of K, depend-
ing on the clock configuration.
Read. Read operations are used to output the
contents of the Memory Array, the Electronic Sig-
nature, the Status Register, the CFI, the Block
Protection Status, the Configuration Register sta-
tus and the Security Code.
Read operation of the Memory Array may be per-
formed in asynchronous page mode or synchro-
nous burst mode. In asynchronous page mode
data is internally read and stored in a page buffer.
The page has a size of 4 words and is addressed
by ADQ0 and ADQ1 address inputs.
According to the device configuration the following
Read operations: Electronic Signature - Status
Register - CFI - Block Protection Status - Configu-
ration Register Status - Security Code must be ac-
cessed as asynchronous read or as single
synchronous burst mode (see Figure 4). Both Chip
Enable E and Output Enable G must be at VIL in
order to read the output of the memory.
