The 2V to 3.6V supply range lets it operate in both 3.3V and 1.8V logic domains without an extra regulator.","metaTitle":"FM25V20A-PG F-RAM 2Mbit SPI FRAM, 40 MHz, 8-PDIP","metaDescription":"Cypress FM25V20A-PG 2Mbit Ferroelectric RAM, SPI interface at 40 MHz, 2V-3.6V, -40°C to 85°C, 8-pin PDIP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"F-RAM™","Package":"Tube","Technology":"FRAM (Ferroelectric RAM)","Memory Size":"2Mbit","Memory Type":"Non-Volatile","Memory Format":"FRAM","Mounting Type":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","Product Status":"Active","Clock Frequency":"40 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI","Voltage - Supply":"2V ~ 3.6V","Base Product Number":"FM25V20","Memory Organization":"256K x 8","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-PDIP","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.8651","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/62eaa4798890162f7b589879742b29b4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/FM25V20A-PG/alternatives.json"},"ai":{"faq":[{"question":"Is the FM25V20A-PG a drop-in replacement for the FM25V20A?","answer":"The FM25V20A-PG is the same base product (FM25V20) in the 8-pin PDIP package variant. The suffix -PG denotes the through-hole PDIP option. If your existing design uses the FM25V20A in a PDIP footprint, the -PG suffix is the correct ordering code for that package — verify the package code on your BOM matches 8-PDIP."},{"question":"Does the FM25V20A-PG require any external components?","answer":"No external charge pump or write-enable sequencing is needed. FRAM writes at the SPI bus speed directly, so the standard SPI bus signals (SCK, MOSI, MISO, CS) plus supply decoupling are all that is required. A 0.1 µF ceramic close to the supply pin is the usual recommendation."},{"question":"Can the FM25V20A-PG replace a serial EEPROM?","answer":"Yes, in most cases. The FM25V20A-PG uses the same SPI interface and pinout as a standard serial EEPROM, but writes at bus speed with no write-cycle delay and offers essentially unlimited endurance (10^14 read/write cycles) versus EEPROM's typical 1 million cycles. The trade-off is a slightly higher standby current than some EEPROMs, so check the quiescent budget for battery-powered designs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/FM25V20A-PG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/FM25V20A-PG when reusing this data.
