identifies the input and output package connections provided on the device.
Address inputs
Multiplexed Address/Data
Output Enable input. Asynchronous relative to CLK for the Burst mode.
Write Enable input.
Ground
Input/Output Ground
No Connect; not connected internally
Ready output; indicates the status of the Burst read.
Flash Memory RDY (using default "Active HIGH" configuration)

Note: The default polarity for the pSRAM WAIT signal is opposite the default polarity of the
Flash RDY signal.
pSRAM WAIT (using default “Active HIGH” configuration)
V
V
To match polarities, change bit 10 of the pSRAM Bus Configuration Register to 0 (Active
LOW WAIT). Alternately, change bit 10 of the Flash Configuration Register to 0 (Active LOW
RDY)
Clock input. In burst mode, after the initial word is output, subsequent active edges of CLK
increment the internal address counter. Should be at V
Address Valid input. Indicates to device that the valid address is present on the address
inputs.
Low = for asynchronous mode, indicates valid address; for burst mode, causes starting
address to be latched.
High = device ignores address inputs
Hardware reset input. Low = device resets and returns to reading array data
Accelerated input. At V
bypass mode. At V
conditions.
Chip-enable input for pSRAM.
Chip-enable input for Flash. Asynchronous relative to CLK for Burst Mode.
Control Register Enable (pSRAM).
Flash and pSRAM 1.8 Volt-only single power supply.
