Additional Details

The IM6402-1IJL UART typically includes features like a baud rate generator, transmit and receive buffers, and control registers. The baud rate generator allows for precise control of the data transmission speed, ensuring compatibility with different devices. The transmit and receive buffers temporarily store data, allowing for asynchronous communication.

Key technical specifications include the maximum baud rate, the supply voltage range, and the operating temperature range. The device is often available in various package options, such as DIP or SOIC, to accommodate different mounting requirements.

Renesas (formerly Intersil) provides detailed datasheets and application notes for the IM6402-1IJL, which include information on pin assignments, electrical characteristics, and programming considerations. These resources are essential for proper implementation and optimal performance of the UART.
