Optimized for
VME A24D16 Slave Controller
Description
Features
The VMEbus was first standardized in 1981 and is still in wide use. With the
advances in integration technologies, custom integrated VME controllers open the
door for smaller and cheaper systems. Inicore offers a wide range of different VME
slave controllers. Each one optimized for a certain application. The difference lies
mainly in the address and data bus width and the supported data modes.
• ANSI/VITA 1-1994
compliant
• VME slave controller
• Data modes: D8, D16
• Address modes: A16, A24
The VME slave controller shields all the complexity of the asynchronous VMEbus
and provides an easy-to-use, synchronous parallel user side interface towards
custom logic. A built-in interrupter handles all local interrupt requests and
acknowledgments.
• Supports read, write, read-
modify-write and BLT cycles
• Configurable D8 or D16

Applications
Figure 1: Sample application
• Industrial control
• Military
The figure above illustrates a typical application where several peripheral
functions together with the VME slave core as well as a bus bridge are integrated
into one FPGA.
