FT4232H QUAD HIGH SPEED USB TO MULTIPURPOSE UART/MPSSE IC
Datasheet
Version 2.4
Document No.: FT_000060 Clearance No.: FTDI#78
3.1.2
Pin Descriptions
This section describes the operation of the FT4232H pins for 64-pin LQFP and 64-pin QFN. Both the 64-pin
QFN and LQFP packages have the same function on each pin. The function of many pins is determined by
the configuration of the FT4232H. The following table details the function of each pin dependent on the
configuration of the interface. Each of the functions are described in Table 3.1.
(Note: The convention used throughout this document for active low signals is the signal name followed by
#)
Table 3.1 FT4232H Pin Configurations for 64-pin QFN and LQFP package
* RI#/ or TXDEN is selectable in the EEPROM. Default is RI#.
