Flash memory means the program is retained without battery backup — no risk of losing the application during a battery swap or extended power-down. Rated for 10000 write cycles maximum. In a typical machine where the program is updated a few times per year, this endurance covers the equipment's service life. For applications requiring frequent field re-flashing (e.g., multi-product changeover), budget the cycle count against the expected update frequency. ## Hardware protection and transfer controls A PROTECT switch on the cassette prevents accidental overwrites — slide it to lock before leaving the panel. The Data transfer button lets you initiate a program transfer without a programming tool, useful for field service or quick clone operations.","metaTitle":"Mitsubishi Electric FX3U-FLROM-64L Flash-RAM Memory Cassette","metaDescription":"Mitsubishi Electric FX3U-FLROM-64L Flash-RAM memory cassette for FX3U PLCs. 64000-step capacity, 10000 write cycles, PROTECT switch.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["PLCs (Programmable Logic Controllers)"],"specifications":{"Memory type":"Flash memory","Product No.":"FX3U-FLROM-64L","Manufacturer":"Mitsubishi","Product Type":"FX3U Flash-RAM memory cassette","PROTECT switch":"Provided","Shipping Weight":"1 Kg","lifecycle_stage":"mature","Estimated Lead Time":"1 - 10 working days.","Data transfer button":"Provided","Max. allowable write":"10000 times","Max. memory capacity":"64000 steps"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$166.37 – $221.00","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/72a083152f748f036973de5bfd610803.pdf","sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/FX3U-FLROM-64L/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/mitsubishi/FX3U-FLROM-64L","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/mitsubishi/FX3U-FLROM-64L when reusing this data.
