The device supports I2C bus speeds up to 1 MHz for fast data access, with backward compatibility to 400 kHz and 100 kHz modes. The 128-byte page write buffer allows efficient writing of large data blocks in a single operation. The 1.7V to 5.5V supply range covers both low-voltage and 5V systems. The device provides both hardware write protect (WP pin) that prevents any write operation when asserted, and software-controlled write protect for the upper quadrant of the memory array. The greater than 1 million write cycle endurance and greater than 200 year data retention ensure long-term reliability for calibration data and configuration parameters. The SSHD-B suffix indicates TSSOP-8 package with tape and reel packaging.","working_principle":"The AT24C512C-SSHD-B uses a floating-gate EEPROM cell array organized as 65,536 words of 8 bits each. The I2C interface uses a 2-wire protocol (SDA data, SCL clock) with 7-bit device address (1010xxx) plus R\/W bit. The 16-bit address word (2 bytes) addresses all 65,536 locations. During a page write operation, up to 128 bytes are loaded into the page write buffer and then simultaneously programmed into the EEPROM array during the 5ms internal write cycle. Partial page writes wrap within the 128-byte page boundary. Reading can be sequential (current address read) or random (address-specified read). The WP pin, when tied to VCC, disables all write operations to the entire memory array for data protection. The software write protect allows protecting the upper 1\/4, upper 1\/2, or entire array via a special sequence. The I2C interface supports standard mode (100 kHz), fast mode (400 kHz), and fast mode plus (1 MHz) with corresponding timing requirements.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>A0<\/td><td>Input<\/td><td>Address bit 0 \/ SWP protect<\/td><\/tr><tr><td>2<\/td><td>A1<\/td><td>Input<\/td><td>Address bit 1<\/td><\/tr><tr><td>3<\/td><td>A2<\/td><td>Input<\/td><td>Address bit 2<\/td><\/tr><tr><td>4<\/td><td>VSS<\/td><td>Power<\/td><td>Ground<\/td><\/tr><tr><td>5<\/td><td>SDA<\/td><td>I\/O<\/td><td>Serial data (open-drain, bidirectional)<\/td><\/tr><tr><td>6<\/td><td>SCL<\/td><td>Input<\/td><td>Serial clock<\/td><\/tr><tr><td>7<\/td><td>WP<\/td><td>Input<\/td><td>Write protect (HIGH = protect all)<\/td><\/tr><tr><td>8<\/td><td>VCC<\/td><td>Power<\/td><td>Supply (1.7-5.5V)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Sensor calibration data storage with >200yr retention and hardware WP<\/li><li>Network device MAC address and serial number storage in TSSOP-8<\/li><li>Industrial PLC configuration backup with 1MHz fast I2C access<\/li><li>Medical device patient settings storage with 1M write cycle endurance<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>Microchip<\/td><td>AT24C512C-SSHL-T<\/td><td>TSSOP-8<\/td><td>Same device, different temp range<\/td><\/tr><tr><td>ST<\/td><td>M24M01-RMN6TP<\/td><td>TSSOP-8<\/td><td>1Mbit, higher density, upgrade<\/td><\/tr><tr><td>onsemi<\/td><td>CAT24C512WI-GT3<\/td><td>TSSOP-8<\/td><td>Pin-compatible equivalent<\/td><\/tr><tr><td>Renesas<\/td><td>24LC512-I\/ST<\/td><td>TSSOP-8<\/td><td>Pin-compatible equivalent<\/td><\/tr><tr><td>Microchip<\/td><td>AT24C256C-SSHL-B<\/td><td>TSSOP-8<\/td><td>256Kbit, half density, lower cost<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/6881","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/comments?post=6881"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/6881\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=6881"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=6881"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=6881"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=6881"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
