This document introduces the features and characteristics of the FT232RL USB to RS232 evaluation module.
The EVAL232R evaluation board provides a compact USB‑to‑RS232 converter based on the FT232RL IC. It integrates the USB transceiver, EEPROM, clock generator (6 MHz, 12 MHz, 24 MHz, 48 MHz) and level converters on a 61 mm × 32 mm PCB, and includes a unique FTDIChip‑ID for security dongle applications.
The module operates from 3.3 V to 5.25 V, supports data rates from 300 baud up to 1 Megabaud, and works over an extended temperature range of –40 °C to +85 °C. It is bus‑powered from USB and complies with RoHS and EU directives.
| Supply voltage range | 3.3 V – 5.25 V |
|---|---|
| Clock output frequencies | 6 MHz, 12 MHz, 24 MHz, 48 MHz |
| Operating temperature range | -40 °C to +85 °C |
| Data transfer rates | 300 baud to 1 Megabaud (up to 3 Megabaud non‑standard) |
| Maximum bus power current (default) | 100 mA |
Each FT232RL device is programmed with a unique serial number (FTDIChip‑ID) that can be read over USB and used as a security dongle to protect software.
The module offers five configurable CBUS I/O pins that can be set for functions such as LED indicators, power control, or clock output.
The module supports standard baud rates up to 1 Megabaud and non‑standard rates up to 3 Megabaud.
