The PMC523 is a 16-port serial controller that provides an innovative upgrade path against from obsolescence.
The PMC523 is a flexible solution and a technology insertion which integrates multiple serial I/O channels onto single board 
computers (SBCs) with PCI Mezzanine Card (PMC) sites. Its efficient design packages 16 serial channels onto a single PMC. Additionally, this serial controller utilizes dual octal UARTs to increase overall performance through reduction of programmed I/O operations. This provides an evolutionary path for enhanced software and ultimately protects customers who have already designed systems utilizing the previous generation PMC423.
The PMC523 is a 16 port RS-422 serial controller with a PCI bus 2.3 target interface compliant up to a 33 MHz clock with a 32-bit bus. The ports are accessible via a front 68-pin high-density connector or rear I/O via P14. Flow control is either automatic RTS/CTS or DTR/DSR. Xon/Xoff software flow control is automatic as well.
Pete Thompson, VP of Product Management for Abaco said, “Abaco’s commitment to our customers expands beyond the life cycle of one product, and innovation doesn’t stop after it hits the market. Our team listens to our customers’ needs to develop solutions that will outpace current products and provide an upgrade path to avoid obsolescence in the long run. The PMC523 is evidence of that commitment, as it delivers a clear upgrade path with solutions that will enable our customers to succeed.”
