Microchip Technology's 24LC128 Serial EEPROM
The 24LC128 is a 128-Kilobit Electrically Erasable Programmable Read-Only Memory (EEPROM) chip brought to the market by Microchip Technology, a leader in smart, connected, and secure embedded control solutions. This particular EEPROM provides an ample storage solution for applications requiring non-volatile memory with low-power operation and high endurance.
The 24LC128 features a sizable 128K bits of memory, which is organized as 16,384 words of 8 bits each. This memory can be accessed via a high-speed I2C interface, which supports standard (100 kHz), fast (400 kHz), and fast-plus (1 MHz) modes, making it versatile for various communication requirements. The chip operates across a voltage range of 2.5V to 5.5V, making it suitable for a wide array of applications, from industrial to consumer electronics.
One of the key advantages of the 24LC128 EEPROM is its low-power consumption, which is essential for battery-operated devices. Additionally, it boasts a high endurance of 1 million erase/write cycles and a data retention period of over 200 years, ensuring reliability and longevity of the stored data.
Security features are also part of the 24LC128's design. The device includes a write protect pin to prevent inadvertent writes, and a software write-protect feature for the upper quarter of the array, providing hardware and software data protection options.
For ease of integration, the 24LC128 is offered in several package types, including the standard 8-lead PDIP, surface-mount SOIC, TSSOP, and MSOP packages. This allows designers to choose the package that best fits their space requirements.
In summary, the Microchip 24LC128 EEPROM is a robust and reliable storage solution that offers a significant amount of non-volatile memory, low-power operation, and high data integrity, making it an excellent choice for a multitude of applications that require long-term data storage without the need for a constant power supply.
