![]() It is recommended to leave NC, DNU and RFU pin unconnected.HOLD#, WP# and RESET# pins have a weak internal pull-up resistor and can be left open if not used.Based on the signal integrity simulations, series termination resistors can be added on SPI signals. ![]() IBIS models for Cypress flash devices are available at: under the “Design Models” tab. It is recommended to perform signal integrity simulations using IBIS models before finalizing the design.A reference schematic diagram for Cypress SPI NOR flash devices is given below using S25FL512S. But, we recommend using a simple pull-up resistor on CS# signal to ensure safe and proper power-up and power-down. Is there any reference schematic for Cypress SPI NOR flash devices available?Ĭypress SPI NOR flash devices can be connected directly with memory controllers without any additional components.
