概要

Description

The 24LC512T-I/ST is a 512 Kbit (64 Kbyte) Electrically Erasable Programmable Read-Only Memory (EEPROM) chip manufactured by Microchip Technology. It operates over a wide voltage range of 1.8V to 5.5V, making it suitable for various applications, including consumer electronics, automotive, and industrial systems.
The device communicates via the I2C (Inter-Integrated Circuit) protocol, allowing multiple devices to be connected on the same bus with unique addresses. It features a fast data transmission rate of up to 1 MHz, enabling efficient data transfer.
Key characteristics include a built-in write protection feature, page write capability (up to 32 bytes), and the ability to retain data for up to 100 years. The 24LC512T-I/ST is ideal for applications requiring non-volatile storage, such as configuration data, calibration constants, and user settings. Its compact 8-pin SOIC or TSSOP packaging enhances integration into space-constrained designs.

Features

The 24LC512T-I/ST is a 512 Kbit (64 Kbyte) EEPROM (Electrically Erasable Programmable Read-Only Memory) memory device. Key features include:
1. Density: 512 Kbits of memory organized as 64 Kbytes (8 bits per byte).
2. Interface: I²C (Inter-Integrated Circuit) compatible, allowing multiple devices on the same bus.
3. Voltage Range: Operates from 1.7V to 5.5V, making it suitable for a variety of applications.
4. Frequency: Supports fast mode (up to 400 kHz) and standard mode (up to 100 kHz) I²C communication.
5. Write Endurance: Capable of 1 million write cycles per byte.
6. Data Retention: Offers data retention of up to 200 years.
7. Packaging: Available in multiple packages, including TSSOP, SOIC, and DFN.
8. Byte and Page Write: Allows for byte-wise or page-wise (up to 16 bytes) writing.
9. Low Power Consumption: Suitable for battery-powered applications due to low active and standby current.
This versatility makes it ideal for applications like data logging, configuration storage, and more in various electronic systems.

Package

The 24LC512T-I/ST is an I2C-compatible EEPROM packaged in an 8-pin SOIC (Small Outline Integrated Circuit) format.

Pinout

The 24LC512T-I/ST is a 512 Kbit (64 Kbytes) I2C EEPROM memory device. It comes in an 8-pin DIP or an 8-pin SOIC package.
Pin Count: 8 pins.
Pin Functions:
1. VCC (Pin 1): Supply Voltage (2.5V to 5.5V).
