Description and Introduction

256 to 1024 ⅴ 8-bit CMOS EEPROMs with I2C-bus interface The **PCF8594C-2T** is a versatile **I²C-bus compatible** memory and I/O expansion integrated circuit designed for embedded systems and microcontroller applications. Manufactured by NXP Semiconductors, this component combines **4 KB of EEPROM memory** with **8-bit I/O port functionality**, making it a practical solution for data storage and peripheral interfacing in compact designs.  

Featuring a **wide operating voltage range (2.5V to 5.5V)**, the PCF8594C-2T is suitable for both low-power and standard-voltage applications. Its **I²C interface** ensures seamless communication with microcontrollers, supporting clock frequencies up to **400 kHz**. The integrated **write-protect function** enhances data security by preventing unauthorized modifications.  

The **8-bit I/O port** can be configured for input or output operations, providing flexibility for interfacing with sensors, switches, or other digital peripherals. Additionally, the **self-timed write cycle** simplifies programming, eliminating the need for external timing management.  

Housed in an **8-pin SO package**, the PCF8594C-2T is ideal for space-constrained applications. Its **low standby current consumption** makes it particularly suitable for battery-powered devices. With its combination of memory and I/O capabilities, this component serves as a reliable choice for embedded systems requiring efficient data handling and peripheral control.
