ECP5 and ECP5-5G sysCONFIG Usage Guide Technical Note

2022-03-23
■Introduction:
●The configuration memory in ECP5™ and ECP5-5G™ FPGAs is built using volatile SRAM; therefore, an external non-volatile configuration memory is required to maintain the configuration data when the power is removed. This non-volatile memory supplies the configuration data to the ECP5 and ECP5-5G devices when it powers up or anytime the device needs to be updated. The ECP5 and ECP5-5G devices provide a rich set of features for programming and configuration of the FPGA. You have many options available to you for building the programming solution that fits your needs. Each of the options available is described in detail so that you can put together the programming and configuration solution that meets your needs. Waveforms presented in this document are for reference only;for detailed timing recommendations refer to ECP5 and ECP5-5G Family DataSheet (FPGA-DS-02012).
