1, using the CP2102 chip
2 , board design, full-featured interface. With RXD TXD RST 3.3V 5V DTR DCD RI RTS CTS and other full-featured interface. Full-featured interface, use the more flexible.
3, with 500mA resettable fuse designed to prevent users from burning the wrong computer USB power connection
4 , with a power indicator .
5 , in-line computer USB interface design , you can not use the computer adapter cable or extension cord .
6, using the Du-Pont line , you can link directly to the customer's target board. Convenient and flexible.
7 , the transmission speed 115200bps easily qualified , definitely more than PL2303.
8 , to borrow a computer USB power supply , 3.3V and 5V power output can be provided directly to the user target board.
9 Note : RXD TXD marked some non-standard equipment , even if not directly , please cross-connect .
CP2102 Introduction :
CP2102 is a USB to serial chip , compact and does not require any peripheral components to be enough as a simple USB-UART program , communication speed up to 1Mbps, it is easy to upgrade the product to a USB serial port , but due to its small size , but it is also MLP package, there are some technical difficulty of welding , so the owner has designed this compact USB-UART module , leads interfaces include 5V, 3.3V, TXD, RXD, GND, which TXD, RXD can be directly connected MCU serial port, convenient for debugging initial product , even 3.3V systems can also take power from the module ( less than 100mA), LED display module is powered and working properly.
Single- chip USB to UART data converters :
- Integrated USB transceiver without external resistors
- Integrated clock without external oscillator
- The integrated 512-byte EEPROM for vendor code for the product code serial number plate power version number and product description and other data to provide storage space
- Power-on reset circuit chip - chip voltage regulator 3.3V output USB function controller
- Full compliance with USB Specification 2.0 (12 Mbps)
- By SUSPEND and RI pin support USB suspend state
Asynchronous serial data bus (UART):
- All handshaking and modem interface signals
- Data formats supported:
• 8 data bits
• Stop bits 1, 2
• Parity: Odd parity, even parity , no parity
- Baud rate 300bps to 921.6kbps
-512 512 byte receive buffer byte transmit buffer
- Support for hardware handshaking or X-On/X-Off
