The HGX232ECM/TR is an SOP-16 (Small Outline Package) RS232 (Serial Port) Integrated Circuit (IC) that is RoHS (Restriction of Hazardous Substances) Compliant. It is manufactured by HGSEMI, a semi-conductor manufacturer specializing in providing standard and customized solutions for a wide range of electronic components. The HGX232ECM/TR is designed to be a low power, noise-tolerant physical layer for communication with RS232 interfaces in various industrial, consumer, and automotive applications. It has a pluggable design, making it easier to integrate into existing designs. It features a selectable receive data rate up to 9.6 Kbit/s and a selectable transmit data rate up to 256 Kbit/s, as well as an integrated 0.1 µF charge pump for a low voltage operation of 2.40V-4.75V. It also features low power consumption of 18 µA, a 75KHz reference clock for the transmitter and receiver FIFOs, and an integrated bootloader ROM. The HGX232ECM/TR is a great choice for designing projects involving low power and noise-tolerant RS232 communication.
