Microchip Technology's 25LC128-E/ST Serial EEPROM
The 25LC128-E/ST is a 128Kb (16,384 x 8) Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) produced by Microchip Technology, designed for storage applications where low-power and low-voltage operations are essential. This device is particularly well-suited for advanced, space-constrained data storage systems and offers a versatile combination of features that make it ideal for a wide range of applications.
Constructed with Microchip's advanced CMOS technology, the 25LC128-E/ST offers a standard SPI interface, enabling high-speed data transfer at rates up to 10 MHz. The device operates across a broad voltage range from 2.5V to 5.5V, making it versatile for both 3.3V and 5V systems. Its endurance is impressive, with a typical value of 1 million erase/write cycles, and the data retention is rated for over 200 years, ensuring the longevity and reliability of stored information.
The 25LC128-E/ST comes in an 8-pin TSSOP (Thin Shrink Small Outline Package) form factor, which is known for its compact footprint and suitability for PCBs where space is at a premium. It also features a page write buffer, allowing up to 64 bytes to be written in a single operation, thus improving write performance when dealing with large amounts of data.
Security is a paramount concern in data storage, and the 25LC128-E/ST addresses this by providing a write-protect pin and write-disable instructions for both hardware and software data protection. Additionally, the device supports sequential read operation, which provides efficient access to the entire memory array with a minimal number of instruction cycles.
Whether it's utilized in personal communication devices, digital cameras, or industrial control systems, the 25LC128-E/ST from Microchip Technology is a reliable choice for designers and engineers looking for a non-volatile memory solution that combines high capacity, small form factor, and robust performance features.
