CLK
Address Inputs, pSRAM Upper Byte Control (A22 available
Address Inputs, pSRAM Lower Byte Control
Address Inputs
Flash Chip Enable Input. Asynchronous relative to CLK for
for 128 Mb Flash)
Multiplexed Address/Data input/output
pSRAM Chip Select Input
the Burst mode.
Output Enable Input. Asynchronous relative to CLK for the
Burst mode.
Write Enable Input.
Device Power Supply (1.7 V–1.95 V).
Ground
No Connect; not connected internally
Ready output; indicates the status of the Burst read.
V
Flash Clock input. The first rising edge of CLK in conjunction
with AVD# low latches address input and activates burst
mode operation. After the initial word is output, subsequent
rising edges of CLK increment the internal address counter.
CLK should remain low during asynchronous access.
Address Valid input. Indicates to device that the valid
address is present on the address inputs (address bits A15–
A0 are multiplexed, address bits A22–A16 are address
only).
V
burst mode, causes starting address to be latched on rising
edge of CLK.
V
Hardware reset input. V
reading array data
At 12 V, accelerates programming; automatically places
device in unlock bypass mode. At V
erase functions. Should be at V
