MCS9835 -- PCI to Dual Serial and Single Parallel Controller
The MCS9835CV-BA is a PCI based single function I/O Adapter. It has two 16C450/16C550 compatible UART channels and one IEEE 1284
compliant parallel port.
The MCS9835CV-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.
Parallel Port interface in MCS9835CV-BA is an IEEE 1284 compliant SPP / PS2 / EPP / ECP Parallel Port that fully supports Centronics interface.
The MCS9835CV-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.
MCS9835CV-BA is designed to be pin compatible with previous version of MCS9835CV. Existing designs of MCS9835 can be migrated to
MCS9835CV-BA without any modification to system design. Software compatibility is also maintained between MCS9835 to MCS9835CV-BA.
