External Master Reset of all Cypress FIFO's

Last Updated: June 13, 2011

- Is there a built-in reset in Cypress FIFO's?
- Is there POR circuitry in Cypress FIFO's?
- Do I need to reset the FIFO on power up?


All Cypress FIFO's require an external Master Reset cycle upon power up. There is no internal built-in circuitry for this. It is very important to complete a full Master Reset cycle, adhering to the specifications laid out in each device's datasheet. If a full Master Reset cycle is not issued upon start up, there is a high chance that the FIFO will not work properly. Please review the datasheet for the FIFO in question to find out the specific requirements for a Master Reset.
