概述

Description

The 24AA32AT-I/SN is a serial EEPROM (Electrically Erasable Programmable Read-Only Memory) device produced by Microchip Technology. It features a 32 Kbit (4 KBytes) memory capacity and operates over a wide voltage range (1.8V to 5.5V). The device communicates using the I2C (Inter-Integrated Circuit) protocol, allowing multiple devices to be connected on the same bus.
Key features include a 256-byte page write capability, which enhances data writing efficiency, and a built-in hardware write protection feature. The 24AA32AT-I/SN is commonly used in applications requiring non-volatile storage, such as configuration settings, calibration data, and other small data storage needs in consumer electronics, automotive, and industrial applications.
The device is available in various packages, including DIP (Dual In-Line Package) and TSSOP (Thin Shrink Small Outline Package), making it suitable for diverse PCB designs. Its low power consumption and reliable performance make it a popular choice for embedded systems.

Features

The 24AA32AT-I/SN is a 32 Kbit I2C EEPROM (Electrically Erasable Programmable Read-Only Memory) from Microchip Technology. Key features include:
1. Memory Size: 32 Kbits (4 Kbytes) with a 256 x 8-bit organization.
2. Interface: I2C (Inter-Integrated Circuit) bus compatible, supporting standard (100 kHz) and fast (400 kHz) modes.
3. Addressing: Supports up to 8 devices on the same bus with a 3-bit hardware address.
4. Write Endurance: Rated for 1,000,000 write cycles per memory location.
5. Data Retention: Capable of retaining data for up to 200 years.
6. Low Power Consumption: Operates with low standby current and power during read/write operations.
7. Write Protection: Features a write-protect pin for protecting memory during critical operations.
This device is ideal for applications requiring non-volatile data storage, such as configuration settings and calibration data in various electronic systems.

Package

The 24AA32AT-I/SN is available in an 8-lead MSOP (Mini Small Outline Package) and an 8-lead SOIC (Small Outline Integrated Circuit) package type.

Pinout

The 24AA32AT-I/SN is a 32K-bit (4K x 8) I2C EEPROM with a total of 8 pins. The pin configuration and functions are as follows:
1. VCC: Power supply pin (typically 2.5V to 5.5V).
2. GND: Ground pin.
3. SDA: Serial Data Line for data transfer.
4. SCL: Serial Clock Line for synchronization of data transfer.
5. WP: Write Protect pin; when tied to VCC, it disables write operations.
6. A0: Address pin; used to set the least significant bit of the device address.
7. A1: Address pin; used to set the next bit of the device address.
8. A2: Address pin; used to set the most significant bit of the device address.
This device supports I2C communication, allowing multiple EEPROMs to be connected on the same bus. It features a page write capability and supports up to 1 million write cycles per memory location.
