7786 - Do MachXO2 and MachXO3 Devices support Soft I²C IP?
Description
Lattice XO2 and XO3 devices do not natively support the conventional I²C Soft IP provided in Propel. Customers who require I²C functionality must use the reference designs provided by Lattice Semiconductor.
To implement I²C communication, Lattice offers reference designs that provide tested implementations for both Controller and Target configurations.
Use the following Lattice reference designs for XO2/XO3 devices as reference:
Description DisplayPort TX IP version 2.1.0 requires the video input to provide blanking interval between active horizontal video lines to ensure correct video data packing. Failure symptoms include no video image output or black screen, even though ...
Description: In PCIe Soft-DMA mode, when an error condition occurs, the DMA IP asserts an interrupt to notify the Host of the detected error. If this interrupt is not properly handled and the DMA is not reset, the system may enter an unrecoverable ...
Title: PCIe DMA in Ring Buffer Operation Mode Cannot Be Stopped Unexpectedly Issue Description: When the PCIe DMA is configured to operate in Ring Buffer DMA mode for continuous transfers, the DMA operation cannot be stopped unexpectedly. If a device ...
For ECP5 non-5G devices, PCIe Endpoint IP is to be used. This IP can only support up to Gen1 speed (2.5 Gbps data rate). For ECP5 5G devices, PCIe-5G Endpoint IP is to be used. This IP supports both Gen1 and Gen2 speed (5 Gbps data rate). After ...
