The 24LC01BT/SN is a Serial EEPROM chip from Microchip. It is a 1 Kb Serial Electrically Erasable Programmable Read-Only Memory (EEPROM). It is a two-wire (I2C) memory with an 8-pin packages. The 24LC01BT/SN is capable of utilizing the full range of I2C communications at up to 100 kHz. It has a single-supply voltage of 1.8 to 5.5 V, and is operable across the industrial 125°C temperature range. The 24LC01BT/SN is available with either TD (Tape and Reel) or TR (Tube) packaging. It is used to store small bits of data that need to be kept in memory when the device is not powered. It is used in applications like Programmable Logic Controllers (PLCs), robotics, security systems, automotive electronics, and other industrial automation equipment.
