1Kbit I2C EEPROM in SOT-23-6 — low-voltage non-volatile storage
The Microchip 24VL014T/OT is a 1Kbit serial EEPROM organized as 128 x 8 bits, accessed via an I²C interface at clock frequencies up to 400 kHz. It stores configuration data, calibration constants, or small logs in a non-volatile array that retains contents without power. The 900 ns access time is typical for this I²C family; the bus protocol handles the timing, so the read cycle is transparent to the host controller. Packaged in a 6-pin SOT-23-6, it occupies minimal board area and is straightforward to hand-solder or rework with hot air.
1.5V to 3.6V supply — why it matters for low-voltage designs
The 1.5V minimum supply voltage is the headline feature of the 24VL014T/OT. Many standard I²C EEPROMs require at least 2.5V or 4.5V, which rules them out in 1.8V-core MCU systems or single-cell battery applications. This part works directly from a 1.8V rail without a level shifter, and the 3.6V upper limit covers 3.3V logic comfortably. If your design already runs on 1.8V or 2.5V I²C buses, this part eliminates an extra voltage translation step on the BOM.
For a procurement decision, this is straightforward: the part is qualified for new designs and repeat production orders without supply-chain clock pressure.
SOT-23-6 — small footprint, rework-friendly
The 6-pin SOT-23-6 package is a common, low-profile surface-mount form factor. Pin pitch is 0.95 mm, so it is visible under a microscope and easy to hand-solder with a fine tip or rework with hot air. The small body (roughly 3 mm x 3 mm) fits into tight layouts, and the package outline is standard across many EEPROM vendors, which simplifies footprint reuse if a second source is needed. No special thermal pad or via stitching is required — standard FR-4 board with a basic soldermask-defined pad works fine.
