Introduction

VT231R is a new high-reliability, high-performance, plug-and-play OOK RF receiver requiring no register configuration, designed for wireless reception applications in the 300–480MHz ISM band. The device meets industrial-grade application requirements, supports data rates of 1–5kbps, and is ideally suited for pairing with low-cost encoder- or MCU-based transmitters. Its operating voltage range is 2.1–5.5V, over which receiver performance remains largely independent of supply voltage. At an operating frequency of 433.92MHz, a receive sensitivity of -113dBm is achieved at only 5.3mA current consumption. By selecting crystals of different frequencies, the device can operate at the commonly used 315MHz frequency or other RF frequencies within the applicable band. The VT231R is available in an SOP8 package.
