概要

Description

The 24LC1026-I/SN is a 1024 Kbit (128 Kbyte) EEPROM (Electrically Erasable Programmable Read-Only Memory) device manufactured by Microchip Technology. It utilizes a two-wire I2C interface, allowing for easy communication with microcontrollers and other digital devices. The "I" designation indicates it operates over a wide voltage range, typically from 1.8V to 5.5V, making it suitable for low-power applications.
Key features include a high-speed mode with a clock rate up to 1 MHz, which enhances data transfer rates. The 24LC1026 supports multiple device addressing, permitting up to eight devices on a single I2C bus. It has a built-in page write capability, facilitating writing up to 32 bytes at once.
This EEPROM is ideal for applications requiring non-volatile storage, such as data logging, configuration storage, and calibration data in consumer electronics, automotive systems, and industrial devices. Its compact 8-pin PDIP or 8-pin SOIC package allows for easy integration into various circuit designs.

Package

The 24LC1026-I/SN is available in an 8-pin MSOP (Mini Small Outline Package) or an 8-pin PDIP (Plastic Dual In-line Package). These compact packages are designed for surface mount and through-hole applications, respectively.

Pinout

The 24LC1026-I/SN is a 256 Kbit I²C EEPROM from Microchip Technology. It features a 8-pin Dual In-line Package (DIP) configuration.
The pin count and functions are as follows:
1. VCC: Power supply pin.
2. GND: Ground pin.
3. SDA: Serial Data Line, used for data transmission.
4. SCL: Serial Clock Line, used for clock signaling.
5. WP: Write Protect pin, controls write protection for the entire memory.
6. A0, A1, A2: Address pins, used to configure the device's I²C address for multiple devices on the same bus.
This device operates in a range of 1.8V to 5.5V and supports byte and page write operations, making it suitable for various memory applications.
