Microchip 24LC1025-I/P 1 Mbit EEPROM 128K x 8-bit I2C DIP-8

Microchip 24LC1025-I/P 1 Mbit EEPROM is a 1 Mbit (128K x 8) serial electrically erasable programmable read-only memory with an I2C-compatible 2-wire serial interface. It operates across a voltage range of 2.5 V to 5.5 V, is designed for low-power embedded systems, and is supplied in a standard 8-pin DIP package.

The device supports both byte write and page write operations, with a 128-byte page write buffer for handling data efficiently. The maximum page write time is 5 ms. Random and sequential reads are supported within specific address boundaries, from 0000h to FFFFh and from 10000h to 1FFFFh, giving developers extensive control over data access.

Key Features

• I2C-compatible 2-wire serial interface for straightforward integration and communication
• Functional address lines allow cascading of up to four devices on the same data bus, for a total system memory expansion of up to 4 Mbit
• Hardware write-protect pin for an additional layer of data security
• Schmitt trigger inputs for superior noise suppression
• Output slope control to eliminate ground bounce
• ESD protection of over 4000 V
• Endurance of more than 1 million erase/write cycles
• Data retention exceeding 200 years
• Maximum read current of 450 µA and standby current of 5 µA

Physical Specifications

The device is housed in an 8-pin DIP (Dual In-line Package) for through-hole mounting. Listed dimensions are Width 3.3, Depth 1.5, and Height 4.3, with a weight of 0.789 g.

Applications

The device is suitable for prototyping, industrial controls, and applications requiring long-term data storage without constant power. It is an ESD-sensitive device, so proper handling precautions must be taken during use.

Choose the Microchip 24LC1025-I/P 1 Mbit EEPROM for embedded designs that require 1 Mbit of non-volatile serial memory in a standard through-hole 8-pin DIP package.
