To provide SRAM address input in byte mode (x8). When CIOs is V
IL
, the SRAM is in
Byte mode and SA provides the most significant address input. When CIOs is V
IH
, the
SRAM is in Word mode and SA becomes a Don’t Care pin.
To output data during Read cycles and receive input data during Write cycles.
Data is internally latched during a flash Erase/Program cycle. The outputs are in
tri-state when OE# is high or BES1# is high or BES2 is low and BEF# is high.
To activate the Flash memory bank when BEF# is low
SRAM Memory Bank Enable To activate the SRAM memory bank when BES1# is low
SRAM Memory Bank Enable To activate the SRAM memory bank when BES2 is high
Output Enable
To gate the data output buffers
Write Enable
To control the Write operations

I/O Configuration (SRAM)
CIOs = V
IH
is Word mode (x16), CIOs = V
IL
is Byte mode (x8)
Write Protect
To protect and unprotect sectors from Erase or Program operation
Reset
To Reset and return the device to Read mode
Ready/Busy#
To output the status of a Program or Erase Operation
RY/BY# is a open drain output, so a 10K
- 100K
pull-up resistor is required to
allow RY/BY# to transition high indicating the device is ready to read.
