Vcc/Vccio Power up sequence of device will not result in excessive current. It does not make much difference whether Vcc is powered up first or Vccio. There is no best or worst sequence . This is both for HC and ZE devices.
No, you do not need to add a ferrite bead between your VCC regulator output and the VCC pins on the FPGA. There are two reasons for not adding the ferrite bead, the first being that the VCC pins are less susceptible to power supply noise so they do ...
The problem in using higher ramp rate than what is described in the datasheet in VCC and VCCAUX supplies is that high current may affect the reliability of the device through time or may degrade its performance. Nonetheless, the FPGA should work as ...
The LatticeXP2 CFG[1:0] and TOE pins are internally linked to the VCC core voltage and can be pulled up to either VCC core or 3.3v. For more information about LatticeXP2 TOE and CFG[1:0] pins, , please refer to LatticeXP2 Family Data Sheet.
The Deployment tool can only generate the Application Specific BSDL file which support the FLASH block thus requiring the JEDEC file. Lattice devices that didn’t have the Flash has no Application Specific BSDL supported for the Deployment tool. The ...
We do not have adaptor to connect J6 header. Also MIPI interface through J6 has not tested. However, by looking at the datasheet of the header pin, Wurth part number: 61302021121 (url: ...
Lattice Technical Support Expectation Please be advised that highest priority for Lattice Technical Support will be given to 1. Software which is not working as expected or suspected bugs. We recommend that customers use the latest software tools and ...
Lattice currently recommends the following for implementing Gigabit Ethernet interfaces: CertusPro-NX FPGAs: Use SERDES-based SGMII or RGMII Certus-NX, MachXO5-NX, and CrossLink-NX: Use RGMII These recommendations are based on updated LVDS-based ...
Glitch Fliter is used to prevent short-duration events of glitches, This is used to prevent False tripping on noise in a system. GLITCHFilter in device constraints , enables 1ns glitch filtering.
Description: Nexus device family has a default I2C slave address of 0x40 and you are allow to modify it based on your requirement. Solution: To permanently modify the I2C address, you can modify the desired value in .fea file and use the Programmer ...
Description: To understand the RTL formatting of the PCIe configuration space in the Nexus' PCIe demos, please refer to the following details. Figure 1 illustrates the initialization of the PCIe configuration space in the Nexus' demo.
