MCS9845 -- PCI to Dual Serial and ISA Controller |
|
| The MCS9845CV-BA is a PCI based single function I/O Adapter. It has two 16C450/16C550 compatible UART channels and ISA style interface to add external UARTS and Parallel Ports.
The MCS9845CV-BA has 32-Byte transmit and receive FIFO for each UART channel. MCS8935CV-BA performs serial-to-parallel conversions on data received from a Serial device, and parallel-to-serial conversions on data received from its CPU.
ISA Style interface is designed to add additional Serial / Parallel Ports by using external ISA peripherals. ISA interface can be used for Serial / Parallel port expansion through ISA : 4 Serial or 2 Serial + 1 Parallel.
The MCS9845CV-BA is ideally suited for PC applications, such as Add-On COM ports and Parallel Ports. It is available in 128-Pin QFP package & fabricated using an advanced submicron CMOS process to achieve low power drain and high-speed requirements.
MCS9845CV-BA is designed to be pin compatible with previous version of MCS9845CV. Existing designs of MCS9845 can be migrated to MCS9845CV-BA without any modification to system design. Software compatibility is also maintained between MCS9845, MCS9845CV-BA.
