概述

Description

The AT24C04D-STUM-T is a 4Kb (512 x 8) I2C-compatible EEPROM (Electrically Erasable Programmable Read-Only Memory) developed by Microchip Technology. It features a 1.8V to 5.5V operating voltage range and is designed for low-power applications. This device allows for up to 1,000,000 write cycles and has a data retention of over 100 years.
The AT24C04D uses a 2-wire I2C interface, making it easy to integrate with microcontrollers and other digital devices. It supports multiple device addresses, allowing multiple EEPROMs to be connected on the same I2C bus.
Key features include:
- 4Kb memory size
- 8-bit data format
- Low power consumption
- Supports high-speed I2C mode (up to 1 MHz)
- Available in various package types, including SOIC and TSSOP
Overall, the AT24C04D-STUM-T is ideal for applications requiring non-volatile memory, such as data logging, configuration storage, and firmware storage in consumer electronics, automotive, and industrial systems.

Package

The AT24C04D-STUM-T is packaged in an 8-lead SOIC (Small Outline Integrated Circuit) package. This type of package is compact and suitable for surface-mount applications.

Pinout

The AT24C04D-STUM-T is a 4 Kbit EEPROM (Electrically Erasable Programmable Read-Only Memory) device that features a 1-Wire interface for communication. It has an 8-pin configuration. The pin assignments are as follows:
1. A0 - Address pin (used to select among multiple devices on the same bus)
2. A1 - Address pin (used to select among multiple devices on the same bus)
3. A2 - Address pin (used to select among multiple devices on the same bus)
4. GND - Ground
5. VCC - Supply voltage (typically 2.5V to 5.5V)
6. SDA - Serial Data Line (data input and output)
7. SCL - Serial Clock Line (synchronizes data transfer)
8. VPP - Programming Voltage (for write operations, typically tied to VCC)
This device is often used in applications requiring non-volatile data storage with low power consumption.
