Supply range is 2.7 V to 3.6 V. Industrial temperature range -40°C to 85°C. Housed in 44-TSOP II. ## 25 ns access — what it buys you 25 ns access time. On a 40 MHz bus, data arrives within one clock cycle. Write cycle time is also 25 ns for a word or page operation, so the store completes in a single bus cycle. That matters for real-time parameter logging where the controller cannot stall for tens of microseconds. ## NVSRAM vs battery-backed SRAM The CY14B108K-ZS25XI stores data in on-chip non-volatile elements, not in a battery-backed SRAM cell. That means no battery replacement schedule, no battery disposal compliance, and no risk of data loss when the battery voltage dips below the retention threshold. The trade-off is a finite number of store cycles (typically 1 million) — fine for configuration and calibration data that changes infrequently, not for a high-frequency write cache. ## Active lifecycle — no LTB clock ticking Active lifecycle status. ROHS3 compliant.","metaTitle":"Cypress CY14B108K-ZS25XI NVSRAM, 8 Mbit, 25 ns, 44-TSOP II","metaDescription":"Cypress CY14B108K-ZS25XI 8 Mbit NVSRAM, 25 ns access time, parallel interface, 2.7V-3.6V, -40°C to 85°C, 44-TSOP II.

The CY7C1061G30-10BVXI and CY7C1061G30-10ZSXI are volatile SRAMs (16 Mbit, 10 ns) in different packages — they are not functional drop-in replacements because they lack non-volatile storage and have a different pinout."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY14B108K-ZS25XI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY14B108K-ZS25XI when reusing this data.
