Address inputs
Multiplexed Address/Data
Output Enable input. Asynchronous relative to CLK for the Burst mode.
Write Enable input.
Ground
No Connect; not connected internally
Ready output. Indicates the status of the Burst read. The WAIT# pin of the
pSRAM is tied to 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
IL
or V
IH
while in asynchronous mode
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
Hardware write protect input. At V
, disables program and erase functions
in the four outermost sectors. Should be at V
IH
for all other conditions.
Accelerated input. At V
, accelerates programming; automatically places
device in unlock bypass mode. At V
, disables all program and erase
functions. Should be at V
IH
for all other conditions.
Chip-enable input for pSRAM.
Chip-enable input for Flash. Asynchronous relative to CLK for Burst Mode.
Control Register Enable (pSRAM).
Flash 1.8 Volt-only single power supply.
pSRAM Power Supply.
Upper Byte Control (pSRAM).
