It runs on a 1.71V to 1.89V supply, which means it drops straight onto a 1.8V digital rail without a separate regulator — a common requirement in battery-operated sensors, portable instruments, and IoT edge nodes where every millivolt of headroom matters. The FRAM technology writes at bus speed with no write-cycle delays and no wear-out mechanism, so it replaces serial Flash or EEPROM in applications that log frequent, small data packets: metering, event recorders, and configuration storage that sees thousands of updates over the product life. ## SPI at 20 MHz – bus timing margin The 20 MHz SPI clock is a moderate rate for FRAM — fast enough for most data-logging and parameter-storage tasks, but not the fastest in the Excelon family. The 8-GQFN package (3.23 x 3.28 mm) keeps trace lengths short, which helps maintain signal integrity on the SPI bus at this speed. No external initialization is required; the device powers up ready to accept commands. ## Active production – no LTB watch needed The CY15V108QI-20LPXI carries an Active lifecycle status from Cypress (now Infineon). There is no announced last-time-buy or obsolescence notice, so it is safe to specify for new designs and production BOMs. The part is ROHS3 compliant. If a replacement is ever needed, the Excelon-LP family includes higher-density or higher-speed siblings, but no direct pin-compatible replacement exists today — the 1.8V-only supply and 8 Mbit density are distinctive. ## Tray packaging – design-in note This part ships in a tray, not tape-and-reel. For high-volume pick-and-place, verify that your feeder setup accepts trays or request a reeled variant from the Excelon-LP family if one exists. The 8-UQFN / 8-GQFN footprint is standard and compatible with typical SPI FRAM layouts.","metaTitle":"Cypress CY15V108QI-20LPXI FRAM, 8Mbit SPI 20MHz 1.8V 8-GQFN","metaDescription":"Cypress CY15V108QI-20LPXI Excelon-LP FRAM, 8Mbit non-volatile memory, SPI interface at 20 MHz, 1.71V–1.89V supply, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"Excelon™-LP,F-RAM™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"Excelon™-LP,F-RAM™","Package":"Tray","Technology":"FRAM (Ferroelectric RAM)","Memory Size":"8Mbit","Memory Type":"Non-Volatile","Memory Format":"FRAM","Mounting Type":"Surface Mount","Package / Case":"8-UQFN","Clock Frequency":"20 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI","Voltage - Supply":"1.71V ~ 1.89V","Memory Organization":"1M x 8","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-GQFN (3.23x3.28)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$35.54","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$35.54000","currency":"USD"},{"qty":10,"price":"$33.41700","currency":"USD"},{"qty":25,"price":"$32.25680","currency":"USD"},{"qty":40,"price":"$31.23700","currency":"USD"},{"qty":80,"price":"$27.49725","currency":"USD"},{"qty":230,"price":"$26.75730","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b67b1b862949a84e220144fc47e1a520.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY15V108QI-20LPXI compatible with 1.8V systems?","answer":"Yes. The supply voltage range is 1.71V to 1.89V, which is a direct match for a 1.8V digital rail. No external regulator is needed."},{"question":"How does CY15V108QI-20LPXI compare to serial Flash memory?","answer":"Unlike serial Flash, FRAM writes at bus speed with no erase cycles and no write-cycle wear. This makes it a better fit for applications that write small data frequently — data logging, configuration storage — where Flash would wear out or introduce write delays."},{"question":"Does CY15V108QI-20LPXI require external initialization?","answer":"No. The device powers up ready to accept SPI commands. No external initialization sequence is required."},{"question":"What is the replacement for CY15V108QI-20LPXI if it becomes obsolete?","answer":"There is no direct pin-compatible replacement announced today. The Excelon-LP family includes other densities and speeds, but none with the same 1.8V-only supply and 8 Mbit density. If a replacement is needed, the closest functional alternative is the CY15B104Q-SXI (4 Mbit, 2.0V supply, 40 MHz SPI) — but verify the supply voltage and footprint compatibility."},{"question":"Where can I buy CY15V108QI-20LPXI?","answer":"This part is available to order through independent distribution.
