概述

Description

The AT24CS02-SSHM-T is a 2-Kbit (256 x 8) Serial EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Microchip Technology. It operates over a supply voltage range of 1.8V to 5.5V, making it suitable for low-power applications. The device communicates using the I2C (Inter-Integrated Circuit) protocol, allowing multiple devices to be connected on a single bus with simple wiring.
Key features include a fast write cycle time, typically around 5 milliseconds, and support for up to one million write cycles, ensuring durability in data storage. It includes a built-in write protection mechanism and can retain data for over 100 years without power. The AT24CS02-SSHM-T is ideal for applications requiring non-volatile memory, such as in consumer electronics, automotive systems, and industrial controls. Its compact size and low power consumption make it suitable for space-constrained designs.

Package

The AT24CS02-SSHM-T is packaged in a 8-lead SOIC (Small Outline Integrated Circuit) format. This surface-mount package is designed for easy integration into electronic circuits, providing a compact solution for memory applications.

Pinout

The AT24CS02-SSHM-T is a 2 Kbit (256 x 8) serial EEPROM from Microchip Technology. It features a total of 8 pins. The pin functions are as follows:
1. VCC - Power supply (2.7V to 5.5V).
2. GND - Ground reference.
3. SDA - Serial Data Line for data input/output.
4. SCL - Serial Clock Line for synchronizing data transmission.
5. WP - Write Protect pin, which can disable write operations.
6. A0 - Address pin used to select one of multiple devices on the same bus.
7. A1 - Address pin used to select one of multiple devices on the same bus.
8. NC - No Connect, not connected internally.
The AT24CS02-SSHM-T operates using an I2C interface, making it suitable for various applications requiring non-volatile memory.
