概述

Description

The 93LC56AT-I/SN is a serial EEPROM (Electrically Erasable Programmable Read-Only Memory) device manufactured by Microchip Technology. It is designed for applications requiring non-volatile storage of data, such as in consumer electronics, automotive, and industrial control systems.
Key features include a 64-bit memory organized into 8 bytes, a 2-wire I2C interface for easy communication, and low power consumption, making it suitable for battery-operated devices. The operating voltage range is typically between 1.8V and 5.5V, ensuring compatibility with various microcontrollers.
The "I" in the part number indicates industrial temperature range (-40°C to 85°C), and the "SN" suffix denotes the package type, which is often an 8-lead SOIC. The device supports multiple data write and read cycles, making it reliable for frequent data updates. Overall, the 93LC56AT-I/SN is a versatile choice for reliable and efficient non-volatile memory solutions in diverse electronic applications.

Package

The 93LC56AT-I/SN is available in an 8-pin SOIC (Small Outline Integrated Circuit) package.

Pinout

The 93LC56AT-I/SN is a 1K-bit EEPROM (Electrically Erasable Programmable Read-Only Memory) device with a total of 8 pins. Here are the pin functions:
1. VCC (Pin 1): Power supply.
2. GND (Pin 2): Ground reference.
3. CS (Chip Select, Pin 3): Active low input to enable communication.
4. SK (Serial Clock, Pin 4): Clock input for timing data transfers.
5. SI (Serial Input, Pin 5): Data input during write operations.
6. SO (Serial Output, Pin 6): Data output during read operations.
7. WP (Write Protect, Pin 7): Active low input to prevent write operations when high.
8. NC (No Connect, Pin 8): Not connected to any internal circuitry.
This device operates using a serial interface, allowing for both read and write operations.
