It combines the fast read/write cycle of an SRAM — no write-cycle delays or wear-out — with automatic store-to-Flash on power-down, so data survives a supply loss without a battery or supercap. The 2.7 V to 3.6 V supply and -40°C to 85°C industrial temperature range suit it for factory automation, motor drives, and outdoor telecom where parameter logging or configuration data must persist across power cycles. ## Industrial temperature and package The -40°C to 85°C operating range covers the majority of industrial and outdoor installations — motor drives in unheated enclosures, solar inverters, and base-station controllers. The 16-SOIC (7.50 mm width) package is a standard footprint for serial memory, easily hand-solderable and compatible with common SOIC-16 test clips for in-circuit programming or verification. ## Lifecycle and compliance The CY14B101PA-SFXI carries an Active product status and ROHS3 compliance. This part is suitable for both new design-ins and production replenishment without supply-risk concerns.","metaTitle":"Infineon CY14B101PA-SFXI NVSRAM, 1Mbit SPI 40MHz","metaDescription":"Infineon CY14B101PA-SFXI 1Mbit NVSRAM with SPI interface, 40MHz clock, 128K x 8 organization, -40°C to 85°C.

The CY14B101PA-SFXI uses an internal store-to-Flash operation on supply dropout."},{"question":"What are the equivalent replacements for CY14B101PA-SFXI?","answer":"The FM25VN10-G from Cypress (now Infineon) is a functional alternative: 1 Mbit non-volatile memory with SPI at 40 MHz, same 128K x 8 organization and -40°C to 85°C range, but using FRAM technology instead of NVSRAM. FRAM offers similar write speed and endurance but with a different internal architecture — verify timing and supply voltage (2.0 V for FM25VN10-G) against your design."},{"question":"How to test or program CY14B101PA-SFXI?","answer":"This part is programmed and read via standard SPI commands at up to 40 MHz. Most production programmers (e.g., Dataman, Xeltek) support the NVSRAM family. For in-circuit testing, a standard SOIC-16 test clip connects to the SPI bus — no special voltage sequence required."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY14B101PA-SFXI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY14B101PA-SFXI when reusing this data.
