Description
The PI7C9X752 (752), is a 1.62V to 3.6V dual Universal Asyn-
chronous Receiver and Transmitter (UART) with 5V tolerant se-
rial (modem) inputs. The highly integrated device is designed for
high bandwidth requirement in communication systems. Each
UART has its own 16C550 compatible set of configuration regis-
ters, TX and RX FIFOs of 64 bytes, fully programmable transmit
and receive FIFO trigger levels, TX and RX FIFO level counters,
automatic RTS/CTS hardware flow control with programmable
hysteresis, automatic software (Xon/Xoff) flow control, RS-485
half-duplex direction control, Intel or Motorola bus interface and
sleep mode for power saving.
Application
ÎÎRemote Access Servers
ÎÎEthernet Network to Serial Ports
ÎÎNetwork Management
ÎÎFactory Automation and Process Control
ÎÎPoint-of-Sale Systems
ÎÎMulti-port RS-232/RS-422/RS-485 Cards
Notes:      
1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3) compliant.
2. See https://www.diodes.com/quality/lead-free/ for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free.
3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm
antimony compounds.
