概述

Description

The 24FC256T-I/MS is a 256 Kbit (32 K × 8) EEPROM (Electrically Erasable Programmable Read-Only Memory) from Microchip Technology. It communicates via the I²C (Inter-Integrated Circuit) interface, allowing for easy integration into various electronic systems. The device operates across a voltage range of 1.8V to 5.5V, making it suitable for both low-power and general applications.
The 24FC256T features a 100 kHz I²C bus speed, enabling efficient data transfer. It supports a page write capability, allowing multiple bytes to be written in a single operation, which enhances performance. The memory is organized in pages of 16 bytes, with an endurance of up to 1 million write cycles and a data retention of over 200 years.
Additionally, the -I/MS suffix indicates that the part is offered in a small, surface-mount MSOP (Mini Small Outline Package) form factor, making it ideal for space-constrained designs. This EEPROM is commonly used in applications like consumer electronics, automotive systems, and telecommunications for data storage and configuration settings.

Features

The 24FC256T-I/MS is a 256 Kbit (32K x 8) I2C-compatible EEPROM (Electrically Erasable Programmable Read-Only Memory) device. Key features include:
1. I2C Interface: Supports standard (100 kHz) and fast (400 kHz) modes.
2. Memory Organization: 32 K x 8 bits with a byte-write capability.
3. Voltage Range: Operates typically from 2.5V to 5.5V, making it suitable for a variety of applications.
4. Write Endurance: Up to 1,000,000 write cycles and data retention of up to 200 years.
5. Low Power Consumption: Minimal power usage in active and standby modes, making it ideal for battery-operated devices.
6. Page Write Capability: Allows writing up to 32 bytes at a time.
7. Self-Timed Write Cycle: No external timing components are required, simplifying design.
These features make the 24FC256T-I/MS suitable for applications requiring non-volatile memory storage, such as in consumer electronics, industrial controls, and data logging systems.
