Description
The 24AA32AT-I/SN is a serial Electrically Erasable Programmable Read-Only Memory (EEPROM) chip developed by Microchip Technology. It features a storage capacity of 32 kilobits, organized in a 4K x 8-bit configuration. Designed for use in a wide range of applications, the chip utilizes the I2C (Inter-Integrated Circuit) bus protocol for communication, which allows it to connect with microcontrollers or other devices over just two wires for data (SDA) and clock (SCL).
This EEPROM operates at a voltage range from 1.7V to 5.5V, making it suitable for a variety of power environments. It is notable for its low power consumption, with active read/write currents and standby current kept minimal. It offers robust data retention capabilities of over 200 years, with a write endurance of one million cycles per byte. The 24AA32AT-I/SN is housed in an 8-lead SOIC (Small Outline Integrated Circuit) package, making it compact and easy to integrate into circuit designs. This chip is commonly used in consumer electronics, automotive systems, and industrial applications where reliable and non-volatile memory storage is required.
