MOTOROLA PMC422FP Mezzanine Card

MOTOROLA PMC422FP Mezzanine Card

DESCRIPTION

the MOTOROLA PMC422FP Mezzanine Card is a versatile and high-performance solution for multi-port serial communication applications. Its compatibility with PCI specifications, programmable baud rates, FIFO buffers, and advanced flow control features make it an ideal choice for a wide range of industrial and embedded systems.

Key Features

Multi-Port Serial Controller: The PMC422FP provides eight serial ports, each of which can be configured for RS232, RS422, or RS485 operation (note: RS232/RS422/RS485 configuration is not applicable to PMC422FP in some contexts, depending on specific product variations or updates).

High-Performance UART: The serial interfaces are implemented using octal UARTs, which combine compatibility with the most commonly used components (16C550-compatible register set) and full support for PCI attributes (such as 32-bit data transfer) to enhance performance.

Programmable Baud Rates: The baud rate is programmable from 100 bits/sec to 921.6 KBits/sec (with a default crystal frequency of 14.7456 MHz).

FIFO Buffers: Each channel has a 64-byte FIFO buffer to avoid data overflow and ensure data integrity.

PCI Compatibility: The PMC422FP is fully compatible with PCI specifications (32 MHz/32-bit).

DIP Switch Configuration: The signal characteristics of each port pair (RS232/RS422/RS485) can be configured through DIP switches.

Advanced Flow Control: The card supports automatic RTS/CTS or DTR/DSR flow control, as well as automatic Xon/Xoff software flow control.

Interrupt Source Register: It features an interrupt source register for all eight ports, providing efficient interrupt handling.

RS485 Half-Duplex Control: With optional delay settings for RS485 half-duplex mode.
