FT232RL Device Characteristics and Ratings
6.1 Absolute Maximum Ratings
The absolute maximum ratings for the FT232R devices are as follows. These are in accordance with the
Absolute Maximum Rating System (IEC 60134). Exceeding these may cause permanent damage to the
device.

* If devices are stored out of the packaging beyond this time limit the devices should be baked before use.
The devices should be ramped up to a temperature of 125°C and baked for up to 17 hours.

Table 6.2 Operating Voltage and Current
Because the UM232R module does not provide access to the OSCI and OSCO pins, the VCC range of this
module has a minimum value of +4.0V. The FT232R device on this module is capable of operating down to
+3.3V but its internal oscillator is only specified for operation down to +4.0V and so an external crystal
must be used when VCC is in the range +3.3V to +4.0V.
