The high-performance, low cost CP21xx USB to UART bridge family offers a complete plug and play interface solution that includes royalty-free driver suites and a comprehensive design ecosystem that enables customers to speed time-to-market. Crystal-less operation, in-system programming memory and small body size packages reduce cost, simplify design and shorten development time. The CP2102 is a highly-integrated?USB-to-UART Bridge Controller?providing a simple solution for updating RS-232 designs to USB using a minimum of components and PCB space. The?CP2102?includes a?USB 2.0 full speed function controller, USB transceiver, oscillator, EEPROM or EPROM, and asynchronous serial data bus (UART) with full modem control signals in a compact 5 x 5 mm QFN-28 package.

MAX232 is a communication IC. It is used to convert TTL Signals to RS232 Signal and vice versa.?MAX232?provides RS-232 voltage level outputs (approx. ? 7.5 V) from a single 5 V supply via on-chip charge pumps and external capacitors. This makes it useful for implementing RS-232 in devices that otherwise do not need any voltages outside the 0 V to 5 V range, as power supply design does not need to be made more complicated just for driving the RS-232 in this case.

The receivers reduce RS-232 inputs (which may be as high as ? 25 V), to standard 5 V TTL levels. These receivers have a typical threshold of 1.3 V, and a typical hysteresis of 0.5 V.

Each part contains one driver and one receiver. The driver slew rates of the MAX485 is not limited, allowing them to transmit up to 2.5Mbps. All parts operate from a single 5V supply.The driver is short-circuit current limited and? protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-impedance state. The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit. The MAX485 is designed for half-duplex applications.
