概述

Description

The AT24C16 is a 16K-bit (2K x 8) serial EEPROM (Electrically Erasable Programmable Read-Only Memory) produced by Microchip Technology. It utilizes a two-wire I²C interface for communication, allowing easy integration with microcontrollers and other digital systems. The device operates over a wide voltage range (typically 1.8V to 5.5V) and supports standard and fast I²C modes, achieving data transfer rates of up to 400 kHz.
The AT24C16 features a page write capability, enabling multiple bytes to be written simultaneously, which enhances efficiency. It also includes an automatic page write protection feature, ensuring data integrity during transactions. The device can be addressed in a multi-device setup, supporting up to 8 devices on the same bus.
With a write endurance of around 1 million cycles and a data retention period of up to 100 years, the AT24C16 is well-suited for applications such as configuration storage, calibration data, and non-volatile data logging in consumer electronics and industrial systems.

Features

The AT24C16 is a 16Kb (2048 x 8-bit) I2C EEPROM (Electrically Erasable Programmable Read-Only Memory) device. Key features include:
1. Interface: I2C compatible, allowing multiple devices on the same bus with a 7-bit addressing scheme.
2. Data Rate: Supports standard mode (100 kHz) and fast mode (400 kHz) I2C operations.
3. Memory Organization: 2048 bytes of memory organized as 256 pages of 8 bytes each.
4. Endurance: Up to 1,000,000 write/erase cycles per memory cell.
5. Data Retention: Retains data for at least 100 years at 25°C.
6. Write Protection: Supports hardware write protection to prevent accidental writes.
7. Low Power Consumption: Operates at low voltage (1.8V to 5.5V) with low active and standby currents.
8. Temperature Range: Available in industrial temperature range (-40°C to +85°C).
These features make the AT24C16 suitable for a variety of applications, including configuration settings, calibration data storage, and more.
