2 Kbit non-volatile storage on a two-wire bus
The AT24HC02C-SSHM-T is a 2 Kbit serial EEPROM organized as 256 x 8 bits, accessed over an I²C bus at clock frequencies up to 1 MHz. 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.
