**UM82C852 Multi I/O For XT <91
***Info:
The Multi-I/O chip, UM82C852 is an integrated chip of UM82C450,
UM82C11, UM82C8167. This chip is a Multi-I/O for PC/XT and PS2 model
30.
The 82C450 asynchronous communications element (ACE) performs
serial-to-parallel conversion on data characters received from
peripheral devices or modems, and parallel-to-serial conversion of
data characters transmitted by the CPU. The complete status of the ACE
can be read at any time during functional operation by CPU. The
information obtained includes the type and condition of the transfer
operations being performed and error conditions.
The 82C11 parallel port provides the user with a bidirectional
parallel data port that fully supports the parallel Centronics type
printer.
The 82C8167 real time clock includes an addressable real time counter,
56 bits of static RAM with an on chip oscillation circuit which can
generate the 32,768 Hz time base.
The 82C852 is packaged in a 68-pin plastic leaded chip carrier.
