RAM UPPER/ LOWER BYTE ENABLES: Low-true; During RAM reads, R-UB#-low enables the RAM
high-order bytes on D[15:8], and R-LB#-low enables the RAM low-order bytes on D[7:0].
R-UB# and R-LB# are only available on SCSP combinations with either SRAM die or PSRAM die.
FLASH WRITE ENABLE: Low-true; WE# controls writes to the selected flash die. Address and data
are latched on the rising edge of WE#.
RAM WRITE ENABLE: Low-true; R-WE# controls writes to the RAM die.
R-WE# is only available on SCSP combinations with RAM die.
FLASH WRITE PROTECT: Low-true; WP# enables/disables the lock-down protection mechanism of
the flash die. WP#-low enables the lock-down mechanism- locked down blocks cannot be unlocked
with software commands. WP#-high disables the lock-down mechanism, allowing locked down blocks
to be unlocked with software commands.
FLASH RESET: Low-true; RST#-low initializes flash internal circuitry and disables flash operations.
RST#-high enables flash operation. Exit from reset places the flash in asynchronous read array mode.
FLASH PROGRAM/ ERASE POWER: A valid F-V
operations. Flash memory array contents cannot be altered when F-V
program operations at invalid F-V

PSRAM MODE: Low-true; P-MODE is used to enter/exit low power mode.
Low power mode is not applicable to 38F2020W0ZTQ1, 38F2020W0ZBQ1, 38F2030W0YTQ1,
38F2030W0YBQ1, 38F2030W0ZTQ2, 38F2030W0ZBQ2, 38F1030W0ZTQ0, 38F1030W0ZBQ0.
P-Mode is only available on SCSP combinations with PSRAM die.
FLASH LOGIC POWER: F1-VCC supplies power to the core logic of flash die #1; F2-VCC supplies
power to the core logic of flash die #2 and #3. Write operations are inhibited when F-V
Device operations at invalid F-V
F2-VCC is only available on SCSP combinations with two or three flash die, and is RFU on SCSP
combinations with only one flash die.
SRAM Power Supply: Supplies power to the SRAM die.
S-VCC is only available on SCSP combinations with SRAM die.
PSRAM Power Supply: Supplies power to the PSRAM die.
P-VCC is only available on SCSP combinations with PSRAM die.
FLASH OUTPUT-BUFFER POWER: Supplies power for the I/O output buffers.
Ground: Connect to ground. Do not float any VSS connection.
Reserved for Future Use: Reserve for future device functionality/ enhancements.
Don’t Use: Do not connect to any other signal, or power supply; must be left floating.
