Read access time is 550 ns, which sets the minimum SCL low-to-high transition window for a single byte read — at 1 MHz the bus period is 1 µs, so the access fits within one clock cycle with margin. Page write time is 5 ms; if the application writes multiple sequential bytes within a page, the total write time stays at 5 ms regardless of byte count, so firmware update loops must budget this as a fixed latency per page. ## Package and board-fit — 8-SOIC, no surprises Cut Tape works for prototypes or small-batch rework without minimum order multiples. RoHS3 compliant (2015/863/EU) with no restricted substances above the threshold — no exemption expiry to track for EU-market products.","metaTitle":"Microchip AT24HC02C-SSHM-T 2Kbit I²C EEPROM, 1 MHz, 8-SOIC","metaDescription":"Active 2Kbit I²C EEPROM by Microchip Technology. 1 MHz clock, 550 ns access, 1.7-5.5V supply, -40 to +85°C. 8-SOIC package.

The AT24HC02C-SSHM-T is faster on reads but offers less storage — if the firmware expects 8 Kbit of addressable space, a 2 Kbit part will not map the full memory map. Check the BOM's required density and read timing before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/AT24HC02C-SSHM-T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/AT24HC02C-SSHM-T when reusing this data.
