A24D32 Datasheet, PDF (1/2 Pages) Actel Corporation – VME A24D32 Slave Controller

Optimized for
VME A24D32 Slave Controller
Description
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.
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.

Figure 1: Sample application
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
in one FPGA.
