2.1.Introduction
● Full speed USB device interface, conforms to USB Specification Version 2.0, only needs crystal and capacitance external.
● Optional: define Vender ID, production ID and list number through external low-cost serial EEPROM.
● Supports 5V and 3.3V power source.
● Low-cost, directly convert serial peripheral equipment, parallel printer and parallel peripheral equipment.
● SOP-28 and SSOP-20 package lead free, compatible with RoHS.
● Only compatible with application layer because interfaces are diverted via USB.
2.2. UART
● Simulate standard serial used to upgrade serial peripheral equipment or increase extra serial via USB.
● Totally compatible with serial application program of computer Windows operation system.
● Hardware full-duplex serial, on-chip transform and receive buffer, supports 50bps~2Mbps
communication baud rate.
● Supporting five, six, seven or eight data bits, supporting odd, even, blank, token and no check.
● Supporting serial transfer and receive enable and serial receive ready etc transfer speed control signal
and MODEM liaison signal.
