B402 - 3U VMEbus Intelligent I/O Controller

Product Description

The B402 CPU board is a universal intelligent VMEbus master and/or slave. Being equipped with sufficient local EPROM/Flash, SRAM, RTC etc., the 32-bit CPU (MC68332) handles one local M-Module.
The B402 makes use of the 16 TPU channels ("Time Processing Units") of the RISC CPU inside the 68332. The TPU channels provide user-defined intelligent timer functions, for example for signal analysis. All TPU lines for the on-board M-Module are available as TTL signals on row C of the M-Module I/O connector.
The B402 can access the VMEbus as an A24/A16/D16 master, and it can also perform slot-1 function. As a slave, the board has 2MB of genuine dual-ported RAM.
Due to its bus architecture and I/O modularity the B402 is suited for a myriad of applications. Together with an M-Module it can be used as a controlling computer or can fulfill I/O tasks in a VMEbus multimaster system.
Its genuine dual-ported RAM makes the B402 also an ideal choice for use as an intelligent data acquisition system or for handling local I/O tasks.
