概述

Description

The 24LC32AT-I/OT is a 32 Kbit (4 K x 8) EEPROM (Electrically Erasable Programmable Read-Only Memory) device produced by Microchip Technology. It utilizes an I²C (Inter-Integrated Circuit) interface, allowing for easy integration with microcontrollers and other devices. The “I” in the part number indicates that it operates over a wide voltage range (1.7V to 5.5V), making it suitable for various applications, including low-power environments.
The 24LC32AT features a typical write cycle time of 5 ms and supports up to 1 million write/erase cycles. It includes a page write capability, allowing data to be written in blocks for efficiency. The device supports simple address and data byte protocols, enabling sequential reads and writes.
Common applications include data storage in consumer electronics, automotive systems, and industrial applications where non-volatile memory is essential. Its compact size and versatile operation make it a popular choice for developers seeking reliable memory solutions.

Features

The 24LC32AT-I/OT is a 32Kb (4K x 8) I2C EEPROM (Electrically Erasable Programmable Read-Only Memory) from Microchip Technology. Key features include:
1. Memory Organization: 32Kbits of EEPROM divided into 4 pages of 32 bytes each.
2. I2C Interface: Supports standard (100 kHz) and fast (400 kHz) modes.
3. Wide Voltage Range: Operates from 2.5V to 5.5V, making it suitable for various applications.
4. Low Power Consumption: Typical active current is 1 mA, with a standby current of less than 1 µA.
5. Byte and Page Write Modes: Supports single-byte writes and page writes (up to 16 bytes at a time).
6. Endurance: Capable of 1 million write/erase cycles per byte, with data retention of over 100 years.
7. Write Protection: Provides hardware write protection features for enhanced data integrity.
8. Temperature Range: Available in industrial temperature ranges (-40°C to 85°C).
This makes it ideal for applications in consumer electronics, automotive, and industrial systems needing reliable non-volatile memory storage.

Package

The 24LC32AT-I/OT is typically available in an 8-lead MSOP (Miniature Small Outline Package) or 8-lead PDIP (Plastic Dual In-Line Package) configuration. This EEPROM is designed for low-power applications and features I2C-compatible communication.

Pinout

The 24LC32AT-I/OT is a 32 Kbit (4 K x 8) EEPROM with a pin count of 8. The functions of its pins are as follows:
1. VSS (Pin 1): Ground connection.
2. VCC (Pin 2): Power supply voltage (typically 2.5V to 5.5V).
3. SDA (Pin 3): Serial data line for data input/output.
4. SCL (Pin 4): Serial clock line for synchronizing data transfer.
5. WP (Pin 5): Write protect pin; when high, it prevents write operations.
6. A0 (Pin 6): Device address pin; used for selecting multiple devices on the same bus.
7. A1 (Pin 7): Another device address pin for additional address selection.
8. A2 (Pin 8): A third device address pin for further addressing options.
