What this 2Kbit I²C EEPROM brings to the bus
The Microchip 24LC024HT-I/SN is a 2Kbit serial EEPROM organized as 256 x 8 bits, communicating over an I²C interface at up to 1 MHz. That 1 MHz clock rate is the headline — it is twice the speed of the standard 400 kHz I²C EEPROMs, which matters when the MCU is polling calibration constants or booting from serial memory. The 400 ns access time sets the minimum SCL high/low period, so firmware needs to account for that when configuring the I²C timing registers.
For a 5 V legacy bus or a 3.3 V IoT node, this part sits on the same rail as the MCU.
Housed in an 8-pin SOIC (3.90 mm width), surface-mount. The Tape & Reel variant (TR) is the standard for automated pick-and-place; the Cut Tape (CT) option suits prototype or low-volume builds. The 8-SOIC footprint is common across Microchip's 24LC serial EEPROM family, so a layout for a 24LC024 can also accept a 24LC025 or 24FC04 with the same pinout.
Write cycle and endurance
Write cycle time is 5 ms per word or page. For a 256 x 8 organization, a page write can program up to 16 bytes in one cycle, which keeps the firmware update or parameter storage loop short. No endurance cycle count is listed in this record, but Microchip's standard for this family is typically 1 million erase/write cycles — verify against the full datasheet for your application's write budget.
ROHS3 compliant. For a production BOM, this means no supply discontinuity to plan around.
