MA111

General Description

The MA111 is a highly-integrated USB bridge to support UART protocol, SPI master, Two Wire serial Interface (TWI/I2C) master and GPIO read/write/interrupt/wakeup functions. It includes a USB 2.0 full-speed function controller, USB transceiver, oscillator and on-chip 3.3V regulator for USB transceiver power (that is applied on VDD range from 4.0V to 5.5V).
