Read and write operations are initiated by shifting in a start bit, opcode, and address through DI on the rising edge of SK. During read operations, data is shifted out on DO. The ORG pin selects between 8-bit and 16-bit organization. Write operations are self-timed with auto-clear of the write enable latch, and the busy status can be polled through the DO pin.","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 high)<\/td><\/tr><tr><td>2<\/td><td>SK<\/td><td>Serial Clock input<\/td><\/tr><tr><td>3<\/td><td>DI<\/td><td>Serial Data Input<\/td><\/tr><tr><td>4<\/td><td>DO<\/td><td>Serial Data Output<\/td><\/tr><tr><td>5<\/td><td>GND<\/td><td>Ground<\/td><\/tr><tr><td>6<\/td><td>ORG<\/td><td>Memory Organization select (VCC=x16, GND=x8)<\/td><\/tr><tr><td>7<\/td><td>NC<\/td><td>No Connect<\/td><\/tr><tr><td>8<\/td><td>VCC<\/td><td>Power supply (1.8-6.0V)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Configuration storage for microcontrollers<\/li><li>Calibration data storage<\/li><li>Device serial number storage<\/li><li>Industrial control parameter storage<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Spec1<\/th><th>Spec2<\/th><\/tr><tr><td>93C66B-I\/ST<\/td><td>Microchip<\/td><td>4Kb Microwire EEPROM<\/td><td>SOIC-8<\/td><\/tr><tr><td>AT93C66D<\/td><td>Atmel\/Microchip<\/td><td>4Kb Microwire EEPROM<\/td><td>SOIC-8<\/td><\/tr><tr><td>BR24G04FVT-W<\/td><td>Rohm<\/td><td>4Kb I2C EEPROM<\/td><td>TSSOP-8<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9779","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/comments?post=9779"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9779\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=9779"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=9779"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=9779"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=9779"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
