Meaning
Square brackets are used to designate group membership or to define a group of signals with a
similar function, such as A[21:1].

VCC vs. VCC
When referring to a signal or package-connection name, the notation used is VCC. When
referring to a voltage level, the notation used is subscripted such as VCC
.
This term is used interchangeably throughout this document to denote either a particular die, or
all die in the package.
Device
This is the method used to refer to more than one chip-enable or output enable. When each is
referred to individually, the reference is F1-CE# and F1-OE# (for die #1), and F2-CE# and F2-
OE# (for die #2).
F[3:1]-CE#,
F[2:1]-OE#
When referencing flash memory signals, the notation used is F-VCC or F-VCC, respectively. When
the reference is to PSRAM signals or timings, the notation is prefixed with “P-” (for example, P-
VCC, P-VCC).
When referencing SRAM signals or timings, the notation is prefixed with “S-” (for example, S-
VCC or S-VCC).
F-VCC P-VCC, S-VCC
P-VCC and S-VCC are RFU for stacked combinations that do not include PSRAM or SRAM.
Used to identify RAM OE#, LB#, UB#, WE# signals, and are usually shared between two or
more RAM die. R-OE#, R-LB#, R-UB# and R-WE# are RFU for stacked combinations that do not
include PSRAM or SRAM.
