Description
The MA112AS16 is a highly integrated USB to UART bridge controller designed to facilitate seamless communication between USB-enabled host devices and UART-based peripherals. By integrating a USB 2.0 full-speed function controller, an internal USB transceiver, and a built-in voltage regulator, it simplifies hardware design by eliminating the need for an external crystal or complex interface components.
Specifically designed for robust data transmission, the MA112 provides stable TXD and RXD connectivity for RS-232 applications. It offers a sophisticated, cost-effective alternative to standard bridges like the CH340, with enhanced features such as built-in clock recovery and support for various parity and stop-bit configurations. Its ability to operate in industrial temperature ranges (-40°C to +85°C) and its wide operating voltage support make it an ideal choice for both consumer electronics and demanding industrial instrumentation. The device appears as a standard Virtual COM Port on major Windows operating systems, ensuring broad compatibility and ease of deployment.
