概述

Description

The 24LC256-I/MS is a 256Kb (32K x 8) EEPROM (Electrically Erasable Programmable Read-Only Memory) device from Microchip Technology. It operates over a wide voltage range of 1.8V to 5.5V, making it suitable for low-power applications. The device communicates via the I²C interface, supporting standard and fast modes with speeds up to 400 kHz.
Key features include:
- Memory Organization: 256Kbits organized as 32,768 words of 8 bits each.
- Endurance and Data Retention: Capable of withstanding at least 1 million write cycles and offering data retention of over 100 years.
- Page Write Capability: Allows writing up to 16 bytes in a single operation, enhancing performance.
- Write Protection: Features a hardware write protect pin to prevent accidental writes.
Ideal applications include data logging, configuration storage, and general-purpose memory storage in embedded systems. The 24LC256-I/MS is commonly found in consumer electronics, automotive, and industrial applications due to its reliability and efficiency.

Package

The 24LC256-I/MS is available in an 8-lead MSOP (Thin Shrink Small Outline Package) or an 8-lead PDIP (Plastic Dual In-line Package). These compact package types are designed for surface-mount or through-hole applications, respectively.

Pinout

The 24LC256-I/MS is a 256 Kbit EEPROM (Electrically Erasable Programmable Read-Only Memory) device featuring a total of 8 pins. The pin configuration and their functions are as follows:
1. VCC: Power supply pin (typically 2.5V to 5.5V).
2. GND: Ground pin.
3. SDA: Serial Data Line for data transfer.
4. SCL: Serial Clock Line to synchronize data transfer.
5. WP: Write Protect pin; if connected to VCC, it prevents write operations.
6. A0: Chip Select pin for device addressing (can be left unconnected for single device).
7. A1: Chip Select pin for device addressing (can be left unconnected for single device).
8. A2: Chip Select pin for device addressing (can be left unconnected for single device).
This device uses I2C (Inter-Integrated Circuit) protocol for communication, allowing multiple devices to be connected on the same bus.
