PMC single-board computer A21C

dual-coreNXPPCI Express

The A21C is an NXP (formerly Freescale) QorIQ based single-board computer for embedded industrial applications. The SBC features full VME64 support and can be used as a master or a slave in a VMEbus environment. The A21C provides 1 MB local dual-ported SRAM for slave access and communication between the local CPU and another VMEbus master. The CPU card comes with a single-core P1013 or dual-core P1022 QorIQ processor with up to 1.067 GHz clock frequency and a serial communication architecture. With two Gigabit Ethernetports and one RS232 COM at the front, and DDR3 SDRAM with ECC, Flash and FRAM, the board offers the crucial basics of an industrial computer. To satisfy your needs for mass storage, you can use microSD cards and mSATA plug-in modules. In addition, the A21C can be equipped with up to two XMC or PMC mezzanine cards on shared sites, providing both front I/O (XMC/PMC) and rear I/O (PMC) for functions such as graphics, mass storage, or further Ethernet. The two PMC slots support modules up to 64-bit/133-MHz PCI-X, while the XMC slots are powered by two PCI Express x1 links each. The modular combination of I/O functionality on a single-board computer allows to build up tailored control systems which appear as customized solutions based on standard components. Its sister card, the A21B, offers three M-Module slots instead of XMC/PMC, which are ideal for process I/O requirements. Where there's a need for even more or other I/O, the A21C also includes a custom I/O mezzanine card option that reduces the board by one PMC/XMC slot but provides interfaces like USB 2.0, COM or even custom I/O controlled by the onboard FPGA.
