概要

Description

The AT24C04C-PUM is a 4 Kbit (512 x 8) I²C-compatible EEPROM (Electrically Erasable Programmable Read-Only Memory) from Microchip Technology. This device operates on a supply voltage range of 1.8V to 5.5V and is designed for low power consumption, making it suitable for battery-powered applications.
The AT24C04C-PUM features a two-wire I²C interface, allowing multiple devices to be connected on the same bus, and supports data rates of up to 1 MHz. It offers write protection and has a page write capability (up to 16 bytes), enhancing flexibility in data storage.
The device is packaged in a 8-lead TSSOP (Thin Shrink Small Outline Package) format, making it suitable for compact electronic designs. Applications include data storage in automotive systems, consumer electronics, and industrial controls, where non-volatile memory is essential.
This EEPROM is ideal for storing configuration settings, calibration data, and other critical information that must persist even when power is removed.

Features

The AT24C04C-PUM is a 4 Kbit (512 x 8) I²C EEPROM (Electrically Erasable Programmable Read-Only Memory) device. Key features include:
1. I²C Interface: Supports standard (100 kHz) and fast (400 kHz) modes for communication.
2. Memory Organization: Comprises 512 bytes of EEPROM, organized into 8 pages of 64 bytes each.
3. Write Protection: The device includes write-protect features to prevent accidental data modification.
4. Byte and Page Write: Supports both byte-level and page-level (up to 16 bytes) write operations.
5. Low Power Consumption: Operates at a low voltage (2.7V to 5.5V) with minimal active and standby current.
6. Endurance: Typically supports up to 1 million write/erase cycles per byte.
7. Data Retention: Guarantees data retention of up to 100 years.
8. Temperature Range: Available in industrial temperature range (-40°C to 85°C).
These features make the AT24C04C-PUM suitable for various applications, including consumer electronics, industrial control, and data logging.

Package

The AT24C04C-PUM is available in a 8-lead SOIC (Small Outline Integrated Circuit) package.

Pinout

The AT24C04C-PUM is a 4K-bit I2C EEPROM from Microchip Technology. It features a total of 8 pins. Here are the pin functionalities:
1. VCC: Power supply (typically +1.8V to +5.5V).
2. GND: Ground reference.
3. SDA: Serial Data Line for data transmission.
4. SCL: Serial Clock Line for synchronization of data transmission.
5. WP: Write Protect; when tied to VCC, it prevents write operations.
6. A0, A1, A2: These are address pins used for selecting the device address when multiple devices are connected on the same bus.
The device operates using the I2C communication protocol, allowing multiple devices to be connected on the same bus while enabling read and write operations with specific addressing.
