iMCP HT32SX is a Sigfox® Monoarch RF Transceiver System-in-Package (SIP) developed to give an already solution of connectivity for IoT application. It is the first product of HT Micron company without built-memory featured with small size (LGA package), high perfomance, low energy needed for IoT application. It was designed by HT Micron, a brazilian company in 2019.
