Microchip 128 kB Serial EEPROM 50 ns 8-Pin TSSOP Serial-SPI 25LC128-I/ST

Microchip 25LC128-I/ST is a high-performance 128 kB Serial EEPROM designed for industrial and commercial applications demanding reliable memory storage. Operating with an industry-standard Serial Peripheral Interface (SPI), this EEPROM provides fast and efficient communication supporting clock frequencies up to 10 MHz while maintaining low power consumption with a maximum read and write current of 5 mA at 10 MHz and a minimal standby current of 5 μA at 5.5 V.

The device memory is organized as 16k x 8 bits providing a total capacity of 128 kB. It features a 50 ns maximum random access time enabling rapid data retrieval. Data retention exceeds 200 years with more than one million erase/write cycles, making it highly reliable for long-term use.

This EEPROM supports SPI modes 0 and 3 and includes block write protection options to safeguard quarter, half, or the entire memory array from accidental overwrite or erasure. The package comes in a compact 8-pin Thin Shrink Small Outline Package (TSSOP) with surface-mount capability, allowing easy integration on PCB designs where space is a constraint. Physical dimensions are 6.4 mm in length, 3.1 mm in width, and 1.2 mm in height.

The device operates over an industrial temperature range from -40°C to 85°C, with extended temperature options available up to 150°C, catering to automotive and harsh environment applications. It complies with the automotive AEC-Q100 standard ensuring quality and reliability for automotive electronics.

Typical applications include industrial control systems, automotive electronics, communication equipment, and consumer products requiring non-volatile, programmable memory storage.
