GENERAL DESCRIPTION
It is based on an 80C51type microcontroller-core. Multiple asynchronous and synchronous protocols are supported. In addition, other peripheral modules like keypad and LC-Display can be connected and controlled by ML69240-C49. Interfacing with the host is done via simple commands that are transferred over a RS232 serial port. FEATURES
