概述

Description

The AT24C02C-SSHM-T is a 2-kilobit (256 x 8-bit) EEPROM (Electrically Erasable Programmable Read-Only Memory) designed by Atmel (now part of Microchip Technology). It operates over an I2C (Inter-Integrated Circuit) bus, which allows for easy communication with microcontrollers and other digital devices.
Key features include a wide operating voltage range (1.8V to 5.5V), low power consumption, and an extensive endurance of up to 1 million write cycles. The EEPROM supports multiple device addressing, allowing up to eight devices on the same bus.
Data is stored in a non-volatile manner, making the AT24C02C ideal for applications such as configuration settings, calibration data, and other small data storage needs in consumer electronics, automotive, and industrial applications. Its compact 8-pin SOIC package enables easy integration into various designs.

Features

The AT24C02C-SSHM-T is a 2 Kbit I2C EEPROM from Microchip Technology. Key features include:
1. Memory Organization: 256 x 8 bits or 128 x 16 bits.
2. I2C Interface: Supports standard (100 kHz) and fast mode (400 kHz) I2C communication.
3. Voltage Range: Operates from 1.7V to 5.5V, making it suitable for a wide range of applications.
4. Low Power Consumption: Offers low active and standby current, enhancing energy efficiency.
5. Endurance: Supports up to 1,000,000 write/erase cycles per memory cell.
6. Data Retention: Ensures data retention for at least 100 years.
7. Byte and Page Write: Allows writing data in single bytes or in pages (up to 16 bytes at a time).
8. Packages: Available in various packages including TSSOP and SOIC for versatile design options.
This EEPROM is widely used in applications such as data storage, configuration settings, and calibration data retention in embedded systems.

Package

The AT24C02C-SSHM-T is packaged in a small, 8-lead SOIC (Small Outline Integrated Circuit) package. It features a surface mount design, ideal for space-constrained applications.

Pinout

The AT24C02C-SSHM-T is a 2-kbit I2C EEPROM (Electrically Erasable Programmable Read-Only Memory) device. It features a total of 8 pins. The pin functions are as follows:
1. VCC: Power supply (typically 1.8V to 5.5V).
2. GND: Ground connection.
3. SDA: Serial Data Line, used for data transfer.
4. SCL: Serial Clock Line, used for clocking the data.
5. WP: Write Protect pin, which can be used to protect the memory from write operations.
6. A0, A1, A2: Address pins to set the device address for multiple devices on the same I2C bus.
The AT24C02C-SSHM-T supports a maximum clock frequency of 1 MHz and is suitable for low-power applications, making it ideal for storing configuration data and small amounts of non-volatile data.
