Product details

Overview

SLEXP8019A from Silicon Labs is a USB-to-UART bridge evaluation kit based on the CP2102C IC, providing full-speed USB 2.0 connectivity and UART interface with up to 3 Mbaud baud rate, 195 µA suspend current, and integrated USB transceiver/clock/voltage regulator - used for rapid prototyping of serial communication in diagnostic tools and POS terminals.

For engineers reviewing the SLEXP8019A datasheet, SLEXP8019A pinout, SLEXP8019A application, or SLEXP8019A equivalent, this page delivers verified hardware configuration, board-level I/O mapping, USB CDC driver compatibility, and direct integration guidance for embedded serial interface development.

Technical Context

The SLEXP8019A is a fully assembled, ready-to-use evaluation platform that exposes the CP2102C's USB 2.0 full-speed (12 Mbps) interface and single-channel UART with configurable baud rates up to 3 Mbaud. It includes onboard USB Type-A connector, TX/RX LEDs, and test points for VBUS, RX, TX, RTS, CTS, DTR, DSR, DCD, and RI signals.

Designed for plug-and-play operation under Windows, macOS, and Linux with standard CDC ACM drivers, the board supports hardware flow control (RTS/CTS), modem control signaling (DTR/DSR/DCD/RI), and operates from 3.3 V regulated supply derived from USB VBUS - no external power required.

FAQ

What is the SLEXP8019A used for?

The SLEXP8019A is an evaluation kit for the CP2102C USB-to-UART bridge IC. It enables rapid testing and development of USB serial communication in applications like diagnostic equipment, POS terminals, and embedded system debug interfaces. The SLEXP8019A provides immediate plug-and-play functionality with standard CDC drivers and exposes all critical UART control signals via test points for hardware validation.

Does the SLEXP8019A require external power?

No, the SLEXP8019A is bus-powered exclusively from the USB host port. It derives regulated 3.3 V internally using the CP2102C's integrated voltage regulator and requires no external power supply or batteries. This design ensures portability and simplifies lab or field deployment of the SLEXP8019A during serial interface evaluation.

Which operating systems support the SLEXP8019A out of the box?

The SLEXP8019A works with standard CDC ACM class drivers included natively in Windows (7+), macOS (10.10+), and Linux (kernel 3.4+). No additional driver installation is required for basic UART functionality. The SLEXP8019A enumerates as a virtual COM port, enabling immediate use with terminal emulators or custom host applications.

Can the SLEXP8019A support hardware flow control?

Yes, the SLEXP8019A exposes RTS and CTS signals via dedicated test points, enabling full hardware flow control for high-speed or bursty UART traffic. When configured in the host application, these lines allow automatic throttling of data transmission - a capability confirmed in CP2102C datasheet Section 7.2 and validated on the SLEXP8019A board layout.

Is the SLEXP8019A compatible with the CP2102N or CP2104?

No - the SLEXP8019A is specifically designed for and populated with the CP2102C IC. While CP2102N and CP2104 share functional similarities, they differ in pinout, internal regulator architecture, and USB suspend current (195 µA for CP2102C vs. 500 µA for CP2104). The SLEXP8019A hardware is not interchangeable with those variants.
