General Description
Ordering Information
The Nm9835 is a PCI based dual-channel high perfor-
mance UART with Enhanced bi-directional parallel con-
troller. The Nm9835 offers 16 byte transmit and receive
FIFO for each UART channel and 16 byte FIFO for
printer channel. The Nm9835 perform serial-to-parallel
conversions on data received from a peripheral device,
and parallel-to-serial conversion on data received from
its CPU. In addition Nm9835 fully supports the existing
Centronics printer interface as well as PS/2, EPP, and
ECP modes.
Commercial Grade
Nm9835CV 128-VQFP 0° C to +70° C
Industrial Grade
Nm9835EV 128-VQFP -40° C to +85° C
The Nm9835 is ideally suited for PC applications, such
as high speed COM ports and parallel port. The Nm9835
is available in 128-Pin QFP package, It is fabricated in
an advanced in submicron CMOS process to achieve
low drain power and high speed requirements.
