Pin Name

Functions

AMS1 to A0 Address Inputs

To provide flash address, AMS-A0.

To provide PSRAM address, AMS-A0

DQ15-DQ0 Data Inputs/Outputs

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.

BEF#

Flash Memory Bank Enable

To activate the Flash memory bank when BEF# is low

BES1#

PSRAM Memory Bank Enable To activate the PSRAM memory bank when BES1# is low

BES2

PSRAM Memory Bank Enable To activate the PSRAM memory bank when BES2 is high

OEF#2

Output Enable

To gate the data output buffers for Flash2 only

OES#2

Output Enable

To gate the data output buffers for PSRAM2 only

WEF#2

Write Enable

To control the Write operations for Flash2 only

WES#2

Write Enable

To control the Write operations for PSRAM2 only

OE#

Output Enable

To gate the data output buffers

WE#

Write Enable

To control the Write operations

UBS#

Upper Byte Control (PSRAM)

To enable DQ15-DQ8

LBS#

Lower Byte Control (PSRAM)

To enable DQ7-DQ0

WP#

Write Protect

To protect and unprotect sectors from Erase or Program operation

RST#

Reset

To Reset and return the device to Read mode

VSSF2

Ground

Flash2 only

VSSS2

Ground

PSRAM2 only

VSS

Ground

VDDF
