Microchip Technology's 24LC04BT-I/SN EEPROM

The 24LC04BT-I/SN is a high-performance, 4 Kbit serial Electrically Erasable Programmable Read-Only Memory (EEPROM) device from Microchip Technology. It comes in an 8-pin SOIC (SN) package, designed to operate over an industrial temperature range of -40°C to +85°C, making it well-suited for a wide range of applications that require data storage under harsh environmental conditions.

This EEPROM device utilizes a bidirectional, two-wire I²C bus for communication, which simplifies integration into your existing designs. It supports a voltage range of 2.5V to 5.5V, providing flexibility for various power supply conditions. The 24LC04BT-I/SN is capable of both random and sequential read/write operations, which enhances its versatility for storing configuration parameters, calibration data, or small application data sets.

The memory is organized as 512 x 8 (512 bytes of 8 bits each), which is divided into two 256 x 8 blocks. This organization allows for byte-level and page-level addressing, giving developers the ability to optimize data storage and retrieval efficiency. Additionally, the device features a self-timed erase/write cycle, removing the need for external erase commands and complex programming algorithms.

The 24LC04BT-I/SN also includes a write protect pin to prevent inadvertent writes, which is particularly useful in preventing data corruption during power transitions or system malfunctions. Furthermore, its low-power design ensures minimal power consumption, which is critical for battery-operated and power-sensitive applications.

Microchip's commitment to quality ensures that the 24LC04BT-I/SN EEPROM delivers high reliability and endurance, with a write endurance of one million write cycles and a data retention period of over 200 years. This device is ideal for a multitude of applications, such as in consumer electronics, automotive industries, medical devices, and industrial control systems where long-term data storage is paramount.
