概要

Description

The 24LC1025-I/SN is a serial EEPROM (Electrically Erasable Programmable Read-Only Memory) chip from Microchip Technology. It features a 1-Mbit (128KB) memory capacity, organized as 128 pages of 8 bytes each. This device operates on a supply voltage range of 1.8V to 5.5V, making it suitable for low-power applications.
The "I" in the part number indicates that it comes in an industrial temperature range, while "SN" refers to the specific package type and delivery format. The 24LC1025 uses a 2-wire I2C interface, allowing multiple devices to be connected on the same bus, with a maximum clock speed of 1 MHz.
Key features include self-timed write cycles, an endurance rating of over 1 million write cycles, and data retention of 100 years. This chip is commonly used in applications such as data logging, configuration storage, and any application requiring non-volatile memory.

Package

The 24LC1025-I/SN is available in an 8-lead SOIC (Small Outline Integrated Circuit) package type. This surface-mount package is designed for space-saving applications, commonly used in electronic devices for EEPROM memory.

Pinout

The 24LC1025-I/SN is a 256 Kbit I2C EEPROM (Electrically Erasable Programmable Read-Only Memory) that features a total of 8 pins. The pin configuration and their functions are as follows:
1. VCC (Pin 1): Power supply pin (typically +2.5V to +5.5V).
2. GND (Pin 2): Ground pin.
3. SDA (Pin 3): Serial Data Line for I2C communication.
4. SCL (Pin 4): Serial Clock Line for I2C communication.
5. WP (Pin 5): Write Protect pin to protect the memory from being written to when high.
6. A0 (Pin 6): Address pin for setting the least significant bit of the device address.
7. A1 (Pin 7): Address pin for setting the next bit of the device address.
8. A2 (Pin 8): Address pin for setting the most significant bit of the device address.
The device supports multiple I2C addresses, allowing for up to 8 devices to be connected on the same bus.
