The STMicroelectronics M24C02-RMB6TG is a 2Kbit serial EEPROM organized as 256 x 8 bits, accessed through an I²C interface at up to 400 kHz. It stores configuration parameters, calibration constants, or small firmware look-up tables in designs that need non-volatile memory with byte-level rewritability — think sensor modules, industrial controllers, or telecom line cards. The 900 ns access time is the read-cycle window from the I²C bus; the 5 ms write-cycle time per word or page governs how quickly you can update a parameter.
Package and temperature — what the board sees
Housed in an 8-UFDFN with an exposed pad (2x3 mm footprint), this part is surface-mount only. No AEC-Q grade is stated, so it is not qualified for under-hood or mission-critical automotive paths.
Lifecycle reality — obsolete, sourced through independent channels
STMicroelectronics lists the M24C02-RMB6TG as Obsolete. That means no further factory orders, no last-time-buy window. The part is available today through independent distribution — we source it from franchised-excess inventory and verified broker stock. Every reel is date-code and lot-code traceable; we screen for counterfeit before shipment.
