The Cypress CY14B256I-SFXIT is a 256Kbit non-volatile SRAM organized as 32K x 8, communicating over an I²C bus. It combines the fast read/write cycle of SRAM with non-volatile storage — no battery backup needed, no wear-leveling required.
Submit an RFQ with your target quantity and preferred lead time; the quote will reflect real-time channel supply.
A functional alternative is the Cypress FM24V02A-G, a 256Kbit FRAM with the same I²C interface and 3.4 MHz bus speed. FRAM has near-infinite endurance but different write timing; verify firmware compatibility before substituting.
The suffix 'T' in the order code indicates tape-and-reel packaging, and the part is manufactured to be RoHS-compliant and lead-free per Cypress standard practice. No separate RoHS certificate is required for this active-line part.
The CY14B256I-SFXI is the tube-packaged variant of the same die; the CY14B256I-SFXIT is tape-and-reel. Electrical specs, temperature range, and footprint are identical. Choose the 'T' suffix for automated pick-and-place assembly.
