1. System Overview
The CP2101 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 CP2101 includes a USB
2.0 full-speed function controller, USB transceiver, oscillator, EEPROM and asynchronous serial data bus
(UART) with full modem control signals in a compact 5 x 5 mm QFN-28 package. No other external USB
components are required.
The on-chip EEPROM may be used to customize the USB Vendor ID, Product ID, Product Description
String, Power Descriptor, Device Release Number and Device Serial Number as desired for OEM applica-
tions. The EEPROM is programmed on-board via the USB allowing the programming step to be easily inte-
grated into the product manufacturing and testing process.
Royalty-free Virtual COM Port (VCP) device drivers provided by Silicon Laboratories allow a CP2101-
based product to appear as a COM port to PC applications. The CP2101 UART interface implements all
RS-232 signals, including control and handshaking signals, so existing system firmware does not need to
be modified. In many existing RS-232 designs, all that is required to update the design from RS-232 to
USB is to replace the RS-232 level-translator with the CP2101. Direct access driver support is available
through the Silicon Laboratories USBXpress driver set.
The CP2101 is a mature product and is not recommended for new designs. The CP2102 is a pin and soft-
Silicon Laboratories customer support at www.silabs.com for any questions about replacing the CP2101.
2. Absolute Maximum Ratings
Table 2.1. Absolute Maximum Ratings
Note: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of the devices at those or any other conditions above those
indicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions for
extended periods may affect device reliability.
