1 Introduction

The UM232R is a development module which uses FTDI’s FT232RL, one of FTDI’s range of USB to UART

interface integrated circuit devices. The FT232RL is a USB to serial UART interface with optional clock

generator output, and the FTDIChip-ID™ security dongle feature. In addition, asynchronous and synchronous

bit bang interface modes are available. The FT232RL adds two new functions compared with its predecessors,

effectively making it a “3-in-1” chip for some application areas. The internally generated clock (6MHz, 12MHz,

24MHz, and 48MHz) can be brought out of the device and used to drive a microcontroller or external logic. A

unique number (the FTDIChip-ID™) is burnt into the device during manufacture and is readable over USB,

thus forming the basis of a security dongle which can be used to protect customer application software from

being copied. (Safe-Guard-IT). The UM232R is supplied on a PCB which is designed to plug into a standard

0.6” wide 24 pin DIP socket. All components used, including the FT232RL are Pb-free (RoHS compliant).
