Pin Definitions
The location of the pins in the GW1NS series of FPGA products
varies according to the different packages.
Table 2-5 provides a detailed overview of user I/O, multi-function
pins, dedicated pins, and other pins.
Table 2-5 Definition of the Pins in the GW1NS series of FPGA products
Pin Name
I/O
Description
User I/O Pins
IO[End][Row/Column
Number][A/B]
I/O
[End] indicates the pin location, including L(left)
R(right) B(bottom), and T(top)
[Row/Column Number] indicates the pin
Row/Column number.If [End] is T(top) or
B(bottom), the pin indicates the column number of
the corresponding CFU. If [End] is L(left) or
R(right), the pin indicates the Row number of the
corresponding CFU.
[A/B] indicates differential signal pair information.
Multi-Function Pins
IO[End][Row/Column Number][A/B]/MMM
/MMM represents one or more of the other
functions in addition to being general purpose user
I/O. These pins can be used as user I/O when the
functions are not used.
RECONFIG_N
I, internal weak
pull-up
Start new GowinCONFIG mode when low pulse
READY
I/O
When high level, the device can be programmed
and configured
When low level, the device cannot be programmed
and configured
DONE
I/O
High level indicates successful program and
configure
Low level indicates incomplete or failed to program
and configure
FASTRD_N /D3
I/O
In MSPI mode, FASTRD_N is used as Flash
access speed port. Low indicates high-speed Flash
access mode; high indicates regular Flash access
mode.
Data port D3 in CPU mode
MCLK /D4
I/O
Clock output MCLK in MSPI mode
Data port D4 in CPU mode
MCS_N /D5
I/O
Enable signal MCS_N in MSPI mode, active-low
Data port D5 in CPU mode
MI /D7
I/O
MISO in MSPI mode: Master data input/Slave data
output
Data port D7 in CPU mode
MO /D6
I/O
MISO in MSPI mode: Master data output/Slave
data input
Data port D6 in CPU mode
SSPI_CS_N/D0
I/O
Enable signal SSPI_CS_N in SSPI mod,
active-low, Internal Weak Pull Up
Data port D0 in CPU mode
SO /D1
I/O
MISO in MSPI mode: Master data input/Slave data
output
