概述

Description

The 24LC01B-I/SN is a 1 Kbit (128 x 8) Electrically Erasable Programmable Read-Only Memory (EEPROM) chip produced by Microchip Technology. It uses a two-wire I²C interface for communication, allowing for easy integration into various electronic systems. The device operates with a supply voltage ranging from 1.8V to 5.5V, making it suitable for low-power applications.
Key features include:
- Data Retention: Up to 40 years at 25°C.
- Endurance: Supports up to 1 million write/erase cycles.
- I²C Compatibility: Supports standard and fast modes with speeds up to 400 kHz.
- Byte or Page Write: Allows writing data one byte at a time or in pages of up to 8 bytes.
The 24LC01B-I/SN is commonly used in applications such as microcontroller interfacing, data logging, and storing configuration settings where non-volatile memory is essential. Its small package size and low power consumption make it ideal for portable devices.

Features

The 24LC01B-I/SN is a 1 Kbit (128 x 8) EEPROM (Electrically Erasable Programmable Read-Only Memory) device with the following key features:
1. Interface: I2C compatible, allowing multiple devices on the same bus.
2. Voltage Range: Operates from 2.5V to 5.5V, making it suitable for low-voltage applications.
3. Speed: Supports standard (100 kHz) and fast (400 kHz) I2C modes.
4. Memory Organization: 128 x 8 bits with an internal organization that allows random access.
5. Write Cycles: Endurance of 1 million write cycles per byte.
6. Data Retention: Retains data for up to 100 years at 25°C.
7. Built-in Write Protection: Features a hardware write-protect pin, preventing accidental writes.
8. Small Package Options: Available in various packages, including SOIC and TSSOP, suitable for space-constrained applications.
