defines the signals shown in
ADDRESS INPUTS for memory addresses. Addresses are internally latched during a program or
erase cycle.
DATA INPUTS/OUTPUTS:
The data balls float to tristate when the chip is deselected or the outputs are disabled.
FLASH CHIP ENABLE: Activates the flash internal control logic, input buffers, decoders, and
sense amplifiers.
SRAM CHIP SELECT1: Activates the SRAM internal control logic, input buffers, decoders, and
sense amplifiers.
SRAM CHIP SELECT2: Activates the SRAM internal control logic, input buffers, decoders, and
sense amplifiers.
FLASH OUTPUT ENABLE: Enables flash memory outputs through the data buffers during a read
operation. F-OE# is active low.
SRAM OUTPUT ENABLE: Enables SRAM outputs through the data buffers during a read
operation. S-OE# is active low.
FLASH WRITE ENABLE: Controls writes to the flash memory command register and memory
array. F-WE# is active low. Addresses and data are latched on the rising edge of the second
F-WE# pulse.
SRAM WRITE ENABLE: Controls writes to the SRAM memory array. S-WE# is active low.
SRAM UPPER BYTE ENABLE: Enables the upper byte for SRAM (DQ
S-UB# is active low.
SRAM LOWER BYTE ENABLE: Enables the lower byte for SRAM (DQ
S-LB# is active low.
