Microchip 25LC1024-I/SM 1Mbit SPI Serial EEPROM SOIC8

The Microchip 25LC1024-I/SM is a 1Mbit serial EEPROM memory device with an SPI-compatible interface, designed for reliable data storage in industrial and embedded applications.

Overview

The device operates from a supply voltage range of 2.5V to 5.5V and supports both byte-level and page-level write operations. Advanced page, sector, and chip erase instructions, typically associated with Flash memory products, provide efficient memory management while retaining the simplicity of SPI communication. The memory configuration is 128K x 8bit, making it suitable for storing configuration data, calibration parameters, and small application logs.

Key Features

• Power-on/off data protection circuitry to safeguard data during power transitions
• Write enable latch and write-protect pin to help prevent unauthorised writes
• Hold pin that allows the host to pause communication, for example when servicing higher-priority interrupts
• 256-byte page for efficient write operations
• 6 ms internal write cycle time (maximum)
• Maximum clock frequency of 20 MHz (at 4.5V to 5.5V)
• Endurance of 1 million erase/write cycles (minimum)
• Data retention of over 200 years
• ESD protection of up to 4000V

Package and Operating Range

The EEPROM is housed in an 8-pin SOIJ package (SOIC-8) with a surface mount design, which is suitable for compact PCB layouts. It operates across an industrial temperature range of -40°C to +85°C, supporting demanding applications. The product dimensions are 3.3 width, 1.5 depth and 4.3 height, with a weight of 0.175 gm.
