Frequently asked questions
Is CY15B102QSN-108SXI RoHS compliant?
Yes, it is ROHS3 Compliant.
What is the closest functional second-source for CY15B102QSN-108SXI?
The Cypress CY15B102Q-SXET is a 2 Mbit FRAM in the same 256K x 8 organization, but it runs at 25 MHz (not 108 MHz), operates from 2.0 V (not 1.8 V to 3.6 V), and is rated -40°C to 125°C with AEC-Q100 automotive qualification. It is a drop-in for temperature-extended or automotive applications, not a speed-equivalent swap.
