Description
The National Instruments PXI-8221 is a robust single-slot PXI module designed to accommodate two PC Card slots, supporting both Type I and II, or a single Type III PC Card. This high-performance module is compatible with 16-bit PCMCIA and 32-bit CardBus PC Cards, ensuring a wide range of applications can be catered to.
With a bus compatibility of PCI, reaching up to 132 Mbytes/s, the PXI-8221 delivers fast and efficient data transfer rates, suitable for demanding system requirements. The module is engineered to work with both 3.3 V and 5 V PC Cards, providing the flexibility needed to support various power requirements.
Interrupt handling is managed through Serialized IRQ, which is particularly adept at managing ISA legacy components within a PCI-based system. This feature ensures smooth integration and communication between older ISA devices and newer PCI controllers.
Users can easily determine the card status with the help of two LED status indicators that signify proper PC Card installation and configuration. Despite being declared obsolete by National Instruments, the PXI-8221 remains available for purchase and servicing through Apex Waves, providing ongoing support for existing systems.
