FT230XS-R

Controllers Overview

The FT230XS-R is a USB to serial UART interface IC from FTDI, designed for compact PCB layouts. It operates on a single +5V supply with internal 3.3V/1.8V LDO regulators. Data transfer rates range from 300 baud to 3 Mbaud at TTL levels. The device features 512-byte receive and transmit buffers with smoothing technology. It includes fully integrated clock generation, eliminating the need for external crystals. Electrical parameters include an operating current of 8 mA (active) and 70 uA (suspend). The component supports 7 or 8 data bits, 1 or 2 stop bits, and various parity options. It is housed in a 16-pin SSOP package.

Controllers Feature Summary

• Integrated clock generation removes the requirement for external crystal oscillators.
• Configurable CBUS I/O pins allow flexible system integration.
• Supports synchronous and asynchronous bit bang interfaces with RD# and WR# strobes.

Controllers Applications

• Glue-less interface connections to external MCUs or FPGAs
• Compact USB peripheral designs requiring reduced pin counts
• Systems utilizing RS422, RS485, or RS232 communication protocols

Controllers Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape/reel specifications. Ensure compatibility with required voltage levels and driver software versions before integration. Confirm RoHS compliance status through manufacturer datasheets. Check for moisture sensitivity level requirements during storage and handling procedures.

Controllers Selection Notes

Select this component when a small footprint and single-chip USB-to-UART solution are required. It is suitable for designs needing integrated clocking and configurable I/O without external firmware programming. Consider the 16-pin SSOP package constraints and thermal characteristics for the specific application environment.
