Its 550 ns access time sets the read-cycle window: after the address is clocked in, the first data byte is available on the SDA line within 550 ns. For a 1 MHz bus (Fast Mode Plus), that leaves roughly 450 ns of setup margin before the next SCL rising edge — comfortable for most MCU I2C peripherals, but worth checking if the master has a tight SDA hold-time spec. The 1 MHz clock frequency is the maximum bus speed; the part also works at 400 kHz and 100 kHz without any configuration change. ## Write cycle time and endurance The write cycle time is 5 ms per word or page. For a 2Kbit device, a full-chip rewrite (256 bytes) takes 256 × 5 ms if written byte-by-byte, or about 5 ms if the master uses page writes (the page size is not explicitly stated, but the 256 x 8 organization implies a single page). ## Lifecycle and sourcing posture Microchip lists the AT24MAC602-XHM-B as Active.","metaTitle":"Microchip AT24MAC602-XHM-B 2Kbit I2C EEPROM, 550 ns access","metaDescription":"Microchip AT24MAC602-XHM-B 2Kbit I2C EEPROM, 550 ns access time, 1 MHz clock, 1.7V-5.5V, -40°C to 85°C, 8-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Package":"Bulk","Technology":"EEPROM","Access Time":"550 ns","Memory Size":"2Kbit","Memory Type":"Non-Volatile","Memory Format":"EEPROM","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP (0.173\\\", 4.40mm Width)","Clock Frequency":"1 MHz","lifecycle_stage":"eol_hot","Memory Interface":"I²C","Voltage - Supply":"1.7V ~ 5.5V","Memory Organization":"256 x 8","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-TSSOP","Write Cycle Time - Word, Page":"5ms"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.31","stockQuantity":0,"priceTiers":[{"qty":975,"price":"$0.31000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a45b7ac7606f890bfb6cffcc86baca8c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can AT24MAC602-XHM-B replace AT24MAC602-XHM?","answer":"Yes, the AT24MAC602-XHM-T is the tape-and-reel variant of the same die. The AT24MAC602-XHM-B is the bulk-packaged version; functionally they are identical — same 2Kbit I2C EEPROM, same 550 ns access time, same 1 MHz clock, same 8-TSSOP package. The only difference is the shipping medium."},{"question":"What is the replacement for AT24MAC602-XHM-B if unavailable?","answer":"No official replacement is listed. The closest functional peer is the AT24MAC602-XHM-T (same die, tape-and-reel). If a larger density is acceptable, the AT24C04D-SSHM-B offers 4Kbit in an SOIC-8 package with a slightly faster 450 ns access time — but the pinout and footprint differ (SOIC-8 vs TSSOP-8)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/AT24MAC602-XHM-B","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/AT24MAC602-XHM-B when reusing this data.
