CP2102 USB to UART Serial Port Module with Mini Interface

Product Introduction

CP2102 characteristics:

1. Single-chip USB to UART data converter

No external resistor or oscillator required; on-chip power-on reset circuit and on-chip voltage regulator

Integrated 1024-byte EEPROM (can be used to store various types of information)

2. USB function

Compliant with USB2.0 specification, full speed (12Mbps)

The SUSPEND pin supports the USB suspend state

3. UART function

All handshake and modem interface signals

Supported data formats: Data bits: 5, 6, 7, 8; Stop bits: 1, 1.5, 2; Parity bits: Odd parity, Even parity, No parity

Baud rate ranging from 300bps to 1Mbps

576-byte receive buffer; 640-byte transmit buffer

Support hardware or X-On/X-Off handshake

Support event status

4. Virtual COM port device driver support

Windows 8/7/Vista/Server 2003/XP/2000

MAC OS-X/OS-9

Linux 2.40 or later

5. USBXpress driver support

Windows 7/Vista/Server 2003/XP/2000

Windows CE

6. Temperature range

-40 to +85 degrees

Product Features:

Ø Supports Mac, Linux, Android, WinCE, Windows 7/8/8.1/10/11

Ø Support external power supply: 5V or 3.3V

Ø With USB protection device: SP0503

Ø With 3 LEDs: TXD LED, RXD LED, POWER LED

Ø TXD, RXD, RTS, CTS: are led out using bent pin headers

Ø Other functional PINs: reserved solder pads, which can be plugged in from above or below to connect to the user's system (pin headers and pin sockets are provided; the PIN spacing supports insertion into universal boards)

Ø Instructions for use: (taking the access to MCU as an example)

Ø VCCIO: Output 3.3V or 5V (The module is powered by USB, and the jumper cap must be set to 3.3V or 5V)

Ø GND: Connect to GND

Ø TXD: connected to MCU.RX (signal flow: MCU.RX << CP2102 << PC.TX)

Ø RXD: connected to MCU.TX (signal flow: MCU.TX >> CP2102 >> PC.RX)

Ø RTS: connected to MCU.CTS (signal flow: MCU.CTS << CP2102 << PC.RTS)

Ø CTS: connected to MCU.RTS (signal flow: MCU.RTS >> CP2102 >> PC.CTS)

Ø Note: This module converts USB to TTL level. Do not directly connect it to RS232 level to avoid burning out the module.

Ø [Special Note: We provide development examples for VCP (Virtual Serial Port) and the driver library for USBXpress, but do not offer technical support for USBXpress.]
