The ICL3222EIV is an integrated signal interface device that enables reliable communication between RS-232 devices and other asynchronous data terminals and networks. It is designed to provide a cost-effective way to interface a microprocessor or microcontroller with an RS-232 or TTL-level asynchronous serial data stream. The device operates at a low supply voltage, typically 3.3V, or at 5V.

The ICL3222EIV offers several features to meet the needs of most application requirements. These features include a 16C452-compatible UART, a transmit FIFO of 8 bytes, a receive FIFO of 8 bytes, and a baud rate generator of up to 19,200bps. The device also has an internal access port which provides a cost-effective way to read and write data over the interface. There are also masks available which allow the device to be programmed for various data transfers.

In the area of application field, the ICL3222EIV can be used for inter-device communication, such as for cellular phone, PDA, PC, printer and so on. It is also suitable for applications such as serial data burst transmission, asynchronous serial bus communications, FIFO access and memory mapping. The device is designed for long-term reliability and low power consumption, making it an ideal choice for many applications.

As for the working principle of the ICL3222EIV, its main function is to convert TTL/CMOS digital signals into RS-232 compatible signals. It also functions as a line driver providing power and speed control. The device includes a 16C452-compatible UART, an 8-byte FIFO (First In, First Out) that provides buffering for transmit and receive data, a baud rate generator, and a host access port. The device\'s internal register is accessible via the host access port and an internal baud rate generator can be configured by writing data to the registers.

In operation, the ICL3222EIV device will detect incoming RS-232 data, convert it to TTL/CMOS levels, and provides buffering for transmit and receive data. Data is sent through the device at a rate specified by the baud rate generator. The device can be programmed over the host access port for several data transfer modes, including asynchronous serial bus communication, FIFO access, and memory mapping. The device can also provide a very low idle current drain that ensures long-term reliability.

Overall, the ICL3222EIV is an easy to use and cost-effective device that enables reliable communication between RS-232 devices and other asynchronous data terminals and networks. Its low supply current and low idle current drain make it an ideal choice for many applications. The highly integrated device includes a 16C452-compatible UART, a transmit FIFO of 8 bytes, a receive FIFO of 8 bytes, and a baud rate generator of up to 19,200bps, allowing users to configure the ICL3222EIV to their exact requirements. The device also includes an internal access port which provides a cost-effective way to read and write data over the interface.
