The WS3221ECY with TSSOP-16 RS232 ICs ROHS is a transceiver-based integrated circuit manufactured by Guangzhou Guobo Electronics Co. Ltd. It is designed to provide full-speed asynchronous communication (up to 115200 bps) between a device and a host. It is also compatible with various transmission protocols such as 8-bit UARTs, LIN, IrDA, and RS485. Other features include low power consumption, wide operating voltage (3.3-5.5V), high ESD protection, and low data error rate. The product is environmentally friendly as it is compliant with ROHS and has a lead-free finish. Additionally, it has high performance and reliability due to its low power and high ESD protection and is easy to design with due to its small size, with only 16 pins.
