Inputs/
Outputs
Multiplexed address/data (ADQ[15:0]) can be used for
multiple purposes:
• Address input during read operations to access the
RAM buffer and the register
• Data input during program operations
• Commands inputs
• Data output during read operations from the memory
array or from registers
• ADQ[15:0] are left floating when the device is dese-
lected or the outputs disabled.
O-CE#
E
F
Chip Enable
Input • Activates the Flash memory control logic, input
buffers, decoders and sense amplifiers.
• When O-CE# is at VIL, the device is in active mode.
• When O-CE# is at VIH, the memory is deselected, the
outputs are high impedance and the power consump-
tion is reduced to standby level.
O-OE#
G
F
Output Enable
Input
Controls data outputs during the bus read operation of
the memory.
O-WE#
W
F
Write Enable
Input
Controls the bus write operation of the memory's
command interface.
O-RP#
RST
, RP
F
Reset
Input • Provides a hardware reset of the memory.
• When O-RP# is at VIL, the device is in reset mode. All
blocks are in the locked state and the configuration
register is reset.
• When O-RP# is at VIH, the device is in normal opera-
tion. Upon exiting reset mode, the device enters asyn-
chronous read mode, but a negative transition of O-
CE# or O-ADV# is required to ensure valid data
outputs.
O-CLK
CK, K
F
Clock
Input • Synchronizes the memory to the system bus
frequency, during synchronous burst mode.
• The addresses are latched on the first O-CLK rising
edge when O-ADV# is at VIL.
