Unlike EEPROM\/Flash which uses charge storage in floating gates (requiring high voltage for tunneling), F-RAM switches the polarization state of the PZT dipoles with a low voltage pulse. This provides virtually unlimited endurance (10^14 cycles vs 10^6 for EEPROM), instant write (no erase-then-program delay), and extremely long data retention (151 years at 85C).","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>CS#<\/td><td>Chip select (active low)<\/td><\/tr><tr><td>2<\/td><td>SO\/SIO1<\/td><td>Serial out \/ SIO1<\/td><\/tr><tr><td>3<\/td><td>WP#\/SIO2<\/td><td>Write protect \/ SIO2<\/td><\/tr><tr><td>4<\/td><td>VSS<\/td><td>Ground<\/td><\/tr><tr><td>5<\/td><td>SI\/SIO0<\/td><td>Serial in \/ SIO0<\/td><\/tr><tr><td>6<\/td><td>SCK<\/td><td>Serial clock<\/td><\/tr><tr><td>7<\/td><td>HOLD#\/SIO3<\/td><td>Hold \/ SIO3<\/td><\/tr><tr><td>8<\/td><td>VDD<\/td><td>Power supply (3.0-3.6V)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Industrial data logging with frequent writes<\/li><li>Automotive event data recorder<\/li><li>Metering and calibration storage<\/li><li>Critical system state (no power-fail data loss)<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Spec1<\/th><th>Spec2<\/th><\/tr><tr><td>FM25V20-G<\/td><td>Infineon<\/td><td>2Mbit F-RAM<\/td><td>8-SOIC<\/td><\/tr><tr><td>MB85RS1MTPF-G-JNERE1<\/td><td>Fujitsu<\/td><td>1Mbit F-RAM<\/td><td>8-SOP<\/td><\/tr><tr><td>CAT24M01WI-G<\/td><td>onsemi<\/td><td>1Mbit EEPROM<\/td><td>8-SOIC (not F-RAM)<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/9729","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/comments?post=9729"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/9729\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=9729"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=9729"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=9729"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=9729"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
