The UT64BS1X433 Matrix-A™ is a 64-Channel, 1:4 Bus Switch that provides bus isolation for up to four banks of 64 I/O connections.
By providing bus isolation, the UT64BS1X433 can significantly reduce the amount of load capacitance seen by a host processor and memory devices.
The reduction in both load capacitance and delay time significantly increase speed and performance compared to a discrete logic implementations or FPGA memory interface solution.
The UT62BS1X433 also provides logic to control up to eight discrete devices per bank and can interface to four, UT8R4M39, 160Mb SRAM performance memories with any Frontgrade LEON processor, without the need for additional logic, to reduce total overall solution cost.
