MM232R USB - Serial UART Development Module Incorporating Clock Generator
Datasheet Version 1.1
Clearance No.: FTDI# 132
2.2 Features
The MM232R has the following features:
Single chip USB to UART synchronous serial
data transfer interface
Entire USB protocol handled on the chip –
No USB-specific firmware programming
required.
UART interface support for 7 or 8 data bits,
1 or 2 stop bits and odd / even / mark /
space / no parity.
Fully assisted hardware or X-On / X-Off
software handshaking.
Data transfer rates from 300 baud to 3
Megabaud (RS422 / RS485 and at TTL
levels) and 300 baud to 1 Megabaud
(RS232).
FTDI?s royalty -free VCP and D2XX drivers
eliminate the requirement for USB driver
development in most cases.
In-built support for event characters and
line break condition.
USB FTDIChip- ID? feature.
Configurable CBUS I/O pins.
Auto transmit buffer control for RS485
applications.
Transmit and receive LED drive signals.
New 48MHz, 24MHz, 12MHz, and 6MHz
clock output signal Options for driving
external MCU or FPGA.
Receive and transmit buffers for high data
throughput.
Adjustable receive buffer timeout.
Synchronous and asynchronous bit bang
mode interface options with RD# and WR#
strobes.
New CBUS bit bang mode option.
Support for USB suspend and resume.
Integrated 1024 bit internal EEPROM for
storing USB VID, PID, serial number and
product description strings, and CBUS I/O
configuration.
Device supplied preprogrammed with
unique USB serial number.
Support for bus powered, self powered, and
high-power bus powered USB
configurations.
