概述

Description

The AT24C08D-SSHM-T is an 8K-bit (1K x 8) EEPROM (Electrically Erasable Programmable Read-Only Memory) chip from Microchip Technology. It utilizes the I2C (Inter-Integrated Circuit) communication protocol, allowing multiple devices to be connected on the same bus, making it suitable for various applications in embedded systems.
Key features include:
- 1.8V to 5.5V operating voltage range, enabling use in low-power applications.
- Up to 1 million write/erase cycles per memory location, ensuring durability.
- Page write capability, allowing data to be written in blocks for efficiency.
- 64-byte page size for data writing, making it suitable for data logging and storage.
Its compact surface-mount package (SSOP) is designed for easy integration into PCBs, making it ideal for consumer electronics, automotive, and industrial applications. The AT24C08D is widely used for storing configuration settings, calibration data, and other non-volatile information where power loss may occur.

Features

The AT24C08D-SSHM-T is an I2C-compatible EEPROM (Electrically Erasable Programmable Read-Only Memory) with the following key features:
1. Memory Size: 1 Kbit (128 bytes) of memory organized in 16 pages of 8 bytes each.
2. Voltage Range: Operates with a supply voltage of 1.7V to 5.5V, making it suitable for low-voltage applications.
3. I2C Interface: Supports standard I2C bus speeds of 100 kHz and 400 kHz, facilitating communication with microcontrollers.
4. Write Endurance: Offers a minimum of 1 million write/erase cycles per byte, ensuring durability.
5. Data Retention: Maintains data integrity for up to 100 years at 25°C.
6. Byte and Page Write Modes: Allows writing data one byte at a time or in a page, enhancing flexibility.
7. Temperature Range: Suitable for industrial applications with an operating temperature range of -40°C to +85°C.
These features make it suitable for applications such as configuration storage, calibration data, and other non-volatile memory requirements.

Package

The AT24C08D-SSHM-T is packaged in a 8-lead SOIC (Small Outline Integrated Circuit) package. This surface-mount package is designed for EEPROM memory applications, offering a compact solution for electronic circuit design.

Pinout

The AT24C08D-SSHM-T is an I2C-compatible EEPROM (Electrically Erasable Programmable Read-Only Memory) with a pin count of 8.
Pin Functions:
1. VCC: Power supply pin (typically 2.7V to 5.5V).
2. GND: Ground pin.
3. SDA: Serial Data Line, used for data transfer.
4. SCL: Serial Clock Line, used to synchronize data transfer.
5. WP: Write Protect pin, when connected to VCC, prevents write operations.
6. A0, A1, A2: Address pins, used to configure the device's I2C address for multi-device support.
The device has a storage capacity of 1 Kbit (128 bytes) and supports multiple devices on the same I2C bus by using the address pins. It is commonly used for data storage in embedded systems, such as configuration settings or calibration data.
