Description

The AT24C02C-SSPD-T is a 2-kilobit (256 x 8-bit) EEPROM (Electrically Erasable Programmable Read-Only Memory) device from Microchip Technology. It utilizes I2C (Inter-Integrated Circuit) communication protocol, allowing multiple devices to connect using only two wires (SDA and SCL). This chip operates with a supply voltage typically between 1.7V and 5.5V, making it suitable for a wide range of applications, including consumer electronics, automotive, and industrial devices.
The AT24C02C features a standard write cycle time of 5 ms, with up to 1 million write/erase cycles, ensuring durability and reliability. It includes built-in write protection mechanisms to prevent accidental overwrites. The device is packaged in a compact surface mount format (SSPD), enabling easy integration into space-constrained designs.
Overall, the AT24C02C-SSPD-T is ideal for applications needing non-volatile memory storage for configuration settings, calibration data, or any application requiring persistent storage even when power is removed.

Features

The AT24C02C-SSPD-T is a 2K-bit (256 x 8) electrically erasable programmable read-only memory (EEPROM) device designed for low-power applications. Key features include:
1. Interface: I2C-compatible, supporting standard and fast modes, allowing up to 400 kHz data rates.
2. Memory Organization: 256 bytes of memory with a page write capability of 16 bytes.
3. Endurance: Supports a minimum of 1 million write/erase cycles per byte and a data retention of over 40 years.
4. Low Power Consumption: Operates at a wide voltage range (1.7V to 5.5V) with low active and standby current.
5. Addressing: 2-wire addressable with up to 8 devices on the same bus.
6. Package: Available in a small 8-pin SOIC and TSSOP packages, suitable for space-constrained designs.
7. Write Protection: Hardware write protect feature to enhance data security.
These attributes make the AT24C02C-SSPD-T ideal for various applications, including consumer electronics, automotive, and industrial systems.

Package
