概述

Description

The 93LC66C-I/ST is a serial EEPROM (Electrically Erasable Programmable Read-Only Memory) designed for applications requiring non-volatile data storage. It features a 1 Kbit (128 x 8-bit) memory capacity and operates using a simple serial interface, allowing efficient data transfer over a 3-wire protocol (Serial Data Input, Serial Data Output, and Serial Clock).
This EEPROM is designed for low-power applications and can operate at a voltage range of 1.8V to 5.5V, making it suitable for battery-operated devices. The device supports fast data access, with read and write cycles typically in the microsecond range.
The 93LC66C-I/ST is ideal for storing configuration data, calibration settings, or other small amounts of data that need to be retained when the power is turned off. Its compact size and ease of integration make it a popular choice in consumer electronics, automotive systems, and industrial applications.

Features

The 93LC66C-I/ST is a 2-wire serial EEPROM (Electrically Erasable Programmable Read-Only Memory) from Microchip Technology. Key features include:
1. Memory Capacity: 1 Kbit (128 bytes), organized as 16 pages of 8 bits each.
2. Interface: I²C-compatible serial interface for easy integration with microcontrollers.
3. Data Retention: Capable of retaining data for up to 100 years.
4. Write Endurance: Supports at least 1 million write/erase cycles.
5. Operating Voltage: Typically operates between 2.5V and 5.5V, making it suitable for low-voltage applications.
6. Low Power Consumption: Designed for minimal power usage during operation and standby modes.
7. Byte and Page Write: Allows for writing data in both byte and page modes, enhancing flexibility.
8. Temperature Range: Operates reliably over a wide temperature range (-40°C to +85°C).
9. Package Options: Available in various packages, including SOIC and TSSOP.
This device is ideal for applications that require non-volatile storage in compact electronic designs.
