4 verified alternatives for FT232RL
| Alternative | Manufacturer | Relationship | Key differences | Source |
|---|---|---|---|---|
| FT232RQ | FTDI | FunctionalSame function: board or design change needed. | Same FT232R silicon with identical USB-UART function, drivers, and 300 baud to 3 Mbaud range; QFN-32 (5x5mm) versus SSOP-28 - footprint change requires a PCB layout update. | FTDI 官方数据手册 |
| FT231XS-R | FTDI | FunctionalSame function: board or design change needed. | FTDI X-Chip generation: USB to full-handshake UART, 300 baud to 3 Mbaud, SSOP-20 or QFN-20 - different package and pinout; MTP memory instead of EEPROM; no external crystal required. | FTDI 官方数据手册 |
| CP2102N-A02-GQFN24 | Silicon Labs | FunctionalSame function: board or design change needed. | Silicon Labs USBXpress bridge, 300 baud to 3 Mbaud, QFN-24 (4x4mm) - different package, pinout, and Silicon Labs VCP drivers instead of FTDI's; 3.0-3.6V supply range. | Silicon Labs 官方数据手册 |
| CH340G | WCH | FunctionalSame function: board or design change needed. | WCH USB-to-UART in SOP-16, up to 2 Mbps - requires an external 12 MHz crystal; uses WCH CH341 drivers; official WCH datasheet (Chinese-language version). | WCH 官方资料 |
Pre-replacement checklist
- Redraw the footprint - every alternative uses a different package (QFN-32, SSOP-20, QFN-24, SOP-16). See the CP2102 guide for a separate comparison of that USB-UART family.
- Confirm crystal requirements: FT232RQ and FT231XS integrate the clock; CH340G needs an external 12 MHz crystal.
- Swap USB VID/PID and driver packages (FTDI VCP/D2XX versus Silicon Labs VCP versus WCH CH341) in the OS image.
- Re-check 5V-tolerant I/O and power wiring against each datasheet's typical application circuit.
