Visão Geral
Description
The EEPROM is organized in a 4K x 8-bit structure with a page write capability of up to 32 bytes. It features a hardware write-protect pin to safeguard against inadvertent writes, ensuring data integrity. The device has low power consumption, with a typical standby current of 1µA, making it energy-efficient for battery-powered applications.
Available in an 8-pin SOIC package, the 24AA32AFT-I/SN is ideal for use in consumer electronics, automotive, industrial, and other systems requiring reliable data storage and retrieval. Its robust design and ease of use make it a popular choice for designers looking to implement EEPROM in their projects.
Equivalent
1. AT24C32 from Microchip (also previously from Atmel)
2. CAT24C32 from ON Semiconductor
3. M24C32 from STMicroelectronics
4. 24LC32 from Microchip
These alternatives offer similar functionalities like I2C interface and 32Kb memory size, but always check the datasheet for specific compatibility in your application.
Features
1. Memory Capacity: It offers 32Kb of memory, organized as 4,096 x 8.
2. Interface: Utilizes the I2C (Inter-Integrated Circuit) bus protocol, which requires only two wires for communication, making it efficient for embedded applications.
3. Voltage Range: Operates with a wide voltage range, typically from 1.7V to 5.5V, which allows it to be used in a variety of systems.
4. Low Power Consumption: Designed for low power applications, with a standby current of typically less than 1μA.
5. Write Protection: Features include a write protection pin for hardware protection of the entire memory array.
6. Data Retention: Offers over 200 years of data retention and can endure more than 1 million erase/write cycles.
7. Temperature Range: Suitable for industrial applications, operating in a temperature range from -40°C to +85°C.
These features make it an ideal choice for applications requiring reliable, non-volatile memory storage.
Pinout
1. Pin 1 (A0): Device address input.
2. Pin 2 (A1): Device address input.
3. Pin 3 (A2): Device address input.
4. Pin 4 (VSS): Ground.
5. Pin 5 (SDA): Serial Data - Input/Output for I2C communication.
6. Pin 6 (SCL): Serial Clock - Clock input for I2C communication.
7. Pin 7 (WP): Write-Protect - Disables write operations when connected to VCC.
8. Pin 8 (VCC): Supply Voltage.
The chip supports I2C communication, allowing data to be read and written via the SDA and SCL pins. It is used for non-volatile storage, meaning it retains data even when powered off. The address pins (A0, A1, A2) allow for up to eight such devices to be connected on the same I2C bus.
