# Introduction to the AT24C02C - CUM - T Product Series
## 1. Overview
The AT24C02C - CUM - T belongs to the family of Serial Electrically Erasable and Programmable Read - Only Memory (EEPROM) products. Manufactured by Microchip Technology, this product series is designed to offer reliable, non - volatile data storage solutions for a wide range of electronic applications. With its compact size, low power consumption, and high - performance features, it has become a popular choice among designers in various industries.
## 2. Key Features
### 2.1 Memory Capacity
The AT24C02C - CUM - T has a memory capacity of 2 kilobits (2Kb), which is equivalent to 256 bytes. This capacity is suitable for storing small to medium - sized amounts of data, such as configuration settings, calibration data, and user - specific information in electronic devices.
### 2.2 I²C Interface
It utilizes the widely adopted Inter - Integrated Circuit (I²C) interface for communication. The I²C interface is a simple, bidirectional, two - wire serial bus that allows multiple devices to be connected on the same bus. This feature simplifies the hardware design and reduces the number of pins required for communication, making it easy to integrate into existing systems. The device supports a standard mode with a clock frequency of up to 100 kHz and a fast mode with a clock frequency of up to 400 kHz, providing flexibility in different application scenarios.
### 2.3 Low Power Consumption
The AT24C02C - CUM - T is designed with low - power operation in mind. It has a very low standby current, typically in the range of a few microamps. During active read or write operations, the power consumption is also relatively low, which is beneficial for battery - powered devices. This low - power characteristic helps to extend the battery life of portable and handheld devices.
### 2.4 High - Performance Endurance
The product offers a high endurance rating, with a guaranteed minimum of 1 million write cycles. This means that the EEPROM can withstand a large number of write operations over its lifetime, making it suitable for applications where frequent data updates are required. Additionally, it has a data retention period of up to 100 years, ensuring that the stored data remains intact even when the power is removed.
### 2.5 Hardware Write Protection
The AT24C02C - CUM - T features a hardware write - protection mechanism. By connecting the WP (Write Protect) pin to a specific voltage level, the user can protect the entire memory or a portion of it from accidental or unauthorized writes. This provides an additional layer of security for the stored data.
## 3. Package and Pin Configuration
### 3.1 Package Types
The AT24C02C - CUM - T is available in a variety of industry - standard packages, including the 8 - lead SOIC (Small Outline Integrated Circuit) and the 8 - lead TSSOP (Thin Shrink Small Outline Package). These packages are widely used in the electronics industry, making it easy to find compatible printed circuit board (PCB) footprints and assembly processes.
### 3.2 Pin Configuration
- **A0, A1, A2**: These are the address input pins. They are used to set the device address on the I²C bus. By changing the logic levels on these pins, up to 8 devices can be connected to the same I²C bus, allowing for multiple EEPROMs to be used in a single system.
- **SDA**: Serial Data Line. It is a bidirectional pin used for data transfer between the device and the
