概述

Description

The 93AA56AT-I/OT is a serial EEPROM (Electrically Erasable Programmable Read-Only Memory) device produced by Microchip Technology. It features a 1-kbit memory capacity organized into 128 bytes, with each byte being individually addressable. This EEPROM operates over a supply voltage range of 1.8V to 5.5V and communicates using a 2-wire I²C interface, making it compatible with various microcontrollers and digital systems.
The "I" in the part number indicates an industrial temperature range, typically from -40°C to +85°C, while "OT" refers to the operational temperature range. This device is particularly useful for applications requiring non-volatile memory storage, such as configuration settings, calibration data, and small data logging.
Key features include low power consumption, high endurance (up to 1 million write cycles), and data retention of over 100 years, making it suitable for battery-operated devices and long-term data storage applications.

Package

The 93AA56AT-I/OT is offered in an 8-lead TDFN (Thin Dual Flat No-lead) package. This compact package type is designed for space-constrained applications, providing a low-profile solution for memory devices.

Pinout

The 93AA56AT-I/OT is a 8-pin serial EEPROM (Electrically Erasable Programmable Read-Only Memory) device. Its pin count is 8, and the functions of each pin are as follows:
1. VCC (Pin 1): Power supply pin.
2. VSS (Pin 2): Ground reference pin.
3. SDA (Pin 3): Serial Data Input/Output; used for data transfer.
4. SCL (Pin 4): Serial Clock; synchronizes data transfer.
5. WP (Pin 5): Write Protect; used to enable or disable writing to the memory.
6. A0 (Pin 6): Address pin; used to select the device in a multi-device configuration.
7. A1 (Pin 7): Address pin; used to further select the device in a multi-device setup.
8. NC (Pin 8): No Connection; not internally connected.
This device operates using a two-wire interface and is typically used for storing small amounts of data in applications such as sensors and identification systems.
