Board Design Consultation & Schematic Review
280 - Power Manager II: How many I2C loads can I put on an I2C chain for Power Manager II devices?
When using the Power Manager-II; POWR1220AT8, POWR1014A or POWR6AT6, it is important to know the loading and driving source of the full set-up. In a case where there are just a few I2C loads, whether Lattice POWR devices or others, the designer needs ...
6503 - MachXO2: Should I power up Vcc or Vccio first in my board design?
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.
1983 - Should I add a ferrite bead to the VCC core voltage supply?
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 ...
6113 - What happens if you go above the maximum ramp rate of VCC and VCCAUX? In this case, what kind of problems can occur?
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 ...
1320 - LatticeXP2: Which voltage rail should CFG and TOE pins be pulled up to?
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.
6445 - Can you generate an application specific BSDL file for a Lattice devices?
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 ...
6084 - CrossLink-NX: Do we have adaptor to connect for MIPI DPHY Connector on CL-NX-Evaluation Board?
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: ...
