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 ...
There are several ways to do this. In some cases the functions inside a Power Manager II device may be stand alone and not affect the other device controlling other supplies. In the case where there are zones or sections that need to get powered up ...
Dual Boot Mode uses the MCLK as a clock source for the external SPI PROM in user-mode. This requires a pull-up to meet the required rise time of the external SPI flash device. When operated in Dual Boot Mode, the MCLK is an output that needs a ...
An IBIS Model is a mapping of voltage to current values for a given I/O standard, slew rate, and drive strength. User can estimate the output resistance by using a simple slope formula, in relative to the flow of current. Using Ohm's law: Resistance ...
MachXO5 devices base package is based on caBGA and BBG is the variation. Per stated in Part Number Description, Lattice support both BBG256/400 packages. User should follow BBG package Thermal Resistance Specification for MachXO5 devices. Example: ...
