CP2101 Description

Short technical summary and product information.

The Cygnal CP2101 is a versatile single-chip USB to UART bridge designed for seamless data transfer. It features an integrated USB transceiver, eliminating the need for external resistors, and an integrated clock, removing the requirement for an external crystal. This IC includes a 512-byte EEPROM for configuration and a 3.3V on-chip voltage regulator.

Supporting USB Specification 2.0 at full speed (12 Mbps), the CP2101 offers asynchronous serial data bus (UART) capabilities with support for 8 data bits, 1 or 2 stop bits, and odd/even/no parity. It handles baud rates from 300bps to 921.6kbps and includes 512-byte transmit and receive buffers. Hardware or X-On/X-Off handshaking is supported.

This device operates within a self-powered voltage range of 3.0V to 3.6V and a USB bus-powered range of 4.0V to 5.25V. It is housed in a compact 28-pin MLP package (5mm x 5mm) and operates across a wide temperature range of -40°C to +85°C. The CP2101 is suitable for upgrading legacy RS-232 devices to USB, creating cellular phone or PDA interface cables, and building USB to RS-232 serial adapters.
