GoBridge ASSP

 

GoBridge ASSPs are highly integrated, low-power, single-chip devices for interfacing and communicating between various types of peripheal interfaces. The GoBridge ASSPs are ideal for converting from one type of peripheal interface to another, multiplexing between multiple interfaces or demultiplexing to multiple interfaces.

 

The first two devices in the GoBridge ASSP product line are the GWU2X and GWU2U ASSPs, which provide interface conversion between USB and SPI, JTAG, I2C, GPIO and UART. Future ASSP's will be added to the Gowin GoBridge product line soon.

 

Bult-in Interface conversion processing and data buffering
I/O independent power supply, supports 3.3V, 2.5V, 1.8V level standards
Configurable register map
Independent clock adjustment
API provided in C/C++ for host device usage

GWU2X is a USB device to peripheral bridging ASSP supporting SPI Master, I2C Master, JTAG Master and GPIO.  The device is the first interface bridge ASSP in the GoBridge product family.
