ON Semiconductor CAT93C76WI-GT3 Microchip

The ON Semiconductor CAT93C76WI-GT3 is a high-performance, 16-Kb Serial EEPROM (Electrically Erasable Programmable Read-Only Memory) microchip designed for a wide range of applications requiring data storage and retrieval. This device offers non-volatile memory storage, which means it retains stored data even after the power is turned off, making it ideal for configuration settings, device calibration data, and user preferences.

The CAT93C76WI-GT3 operates on a wide voltage range from 1.8V to 5.5V, making it suitable for various low-power and standard applications. It utilizes a three-wire serial interface for communication, which includes Chip Select (CS), Serial Data Input (DI), and Serial Clock (CLK), ensuring compatibility with most microcontrollers and enabling easy integration into your design.

This EEPROM device offers a storage capacity of 16-Kb, organized as 2048 words of 8 bits each (16Kb 8-bit) or 1024 words of 16 bits each (16Kb 16-bit), selectable through software. It features a self-timed write cycle with auto-clear, which simplifies the write operation and enhances the reliability of data storage. The CAT93C76WI-GT3 also supports a write cycle time of 5ms, allowing for efficient write operations.

For data protection, the CAT93C76WI-GT3 includes a hardware and software write protection feature. The hardware write protection is implemented by connecting the Write Protect (WP) pin to VCC. Software write protection is achieved through status register bits, providing a robust solution for securing critical data against unintended writes.

The microchip is available in a compact 8-pin SOIC package, which is ideal for space-constrained applications. It is specified for operation over the industrial temperature range of -40°C to +85°C, ensuring reliable performance in harsh environments.

Overall, the ON Semiconductor CAT93C76WI-GT3 EEPROM is an excellent choice for designers looking for a reliable and flexible non-volatile memory solution. Its wide voltage range, serial interface, and robust data protection features make it a versatile component for a variety of electronic systems.
