Description

The AT24C08C-PUM is an 8-kilobit (1 Kbyte) EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Microchip Technology. It uses I2C (Inter-Integrated Circuit) communication protocol for data transfer, which allows multiple devices to be connected on the same bus. The device operates with a supply voltage range of 1.7V to 5.5V, making it suitable for low-power applications.
The AT24C08C-PUM features a 1 MHz I2C bus speed and supports up to 1 million write cycles, ensuring durability for frequent data updates. It has a built-in Write Protect feature to prevent accidental overwrites. Data is organized in 256-byte pages, allowing for efficient read and write operations.
Common applications include data storage in consumer electronics, automotive systems, and industrial devices, where non-volatile memory is essential for storing configuration settings, calibration data, or other critical information. The package type is often a small 8-pin SOIC, making it ideal for space-constrained designs.

Features

The AT24C08C-PUM is an 8Kb (1K x 8) I2C EEPROM (Electrically Erasable Programmable Read-Only Memory) from Microchip Technology. Key features include:
1. Memory Organization: 8Kbits divided into 1024 bytes, each byte can be individually accessed.
2. I2C Interface: Supports standard (100 kHz) and fast (400 kHz) modes.
3. Write Protection: Supports hardware and software write protection to secure stored data.
4. Byte and Page Write: Allows single-byte writes and multi-byte page writes (up to 16 bytes).
5. Endurance: Capable of enduring 1,000,000 write cycles per byte.
6. Data Retention: Retains data for at least 100 years under typical conditions.
7. Operating Voltage: Typically operates from 1.7V to 5.5V, making it suitable for low-power applications.
8. Package Options: Available in various packages, such as SOIC and TSSOP, for flexibility in design.
This EEPROM is ideal for applications requiring non-volatile storage, such as configuration data and calibration settings.

Package

The AT24C08C-PUM is packaged in a 8-pin UDFN (Ultra Thin Dual Flat No-lead) package. This compact, surface mount package is designed for space-constrained applications, providing a small footprint while offering reliability and ease of handling for electronic designs.

Pinout

The AT24C08C-PUM is an EEPROM (Electrically Erasable Programmable Read-Only Memory) chip with a pin count of 8. It operates using the I²C (Inter-Integrated Circuit) protocol for communication.
The pin functions are as follows:
1. Pin 1 (A0): Address pin for device selection.
2. Pin 2 (A1): Address pin for device selection.
3. Pin 3 (A2): Address pin for device selection.
4. Pin 4 (GND): Ground connection.
5. Pin 5 (SDA): Serial Data Line for data transfer.
6. Pin 6 (SCL): Serial Clock Line for timing control.
7. Pin 7 (WP): Write Protect pin. When connected to VCC, it prevents write operations.
8. Pin 8 (VCC): Power supply pin (typically 2.5V to 5.5V).
This chip provides 1 kilobit of memory organized in 8 pages of 256 bits each.
