AT24C256C-SSHL-T
Brand: Microchip
AT24C256C-SSHL-T is a 256 Kbit (32,768 × 8) serial EEPROM from Microchip with an I²C-compatible 2-wire interface operating up to 1 MHz. With a 64-byte page write buffer and self-timed 5 ms maximum write cycle, it delivers efficient non-volatile storage across a wide 1.7 V to 5.5 V supply range. The device features hardware write protection, endurance exceeding 1 million cycles, and data retention beyond 100 years. Packaged in an 8-pin SOIC rated from -40 °C to +85 °C, it supports up to 8 devices on a shared I²C bus and is factory-programmable for custom data.
