IDT73720/A  
16-BIT TRI-PORT  
BUS EXCHANGER  
Integrated Device Technology, Inc.  
FEATURES:  
DESCRIPTION:  
• High-speed 16-bit bus exchange for interbus communica-  
tion in the following environments:  
— Multi-way interleaving memory  
— Multiplexed address and data busses  
• Direct interface to R3051 family RISChipSet  
— R3051 family of integrated RISController CPUs  
— R3721 DRAM controller  
The IDT73720/A Bus Exchanger is a high speed 16-bit bus  
exchange device intended for inter-bus communication in  
interleaved memory systems and high performance multi-  
plexed address and data busses.  
The Bus Exchanger is responsible for interfacing between  
the CPU A/D bus (CPU address/data bus) and multiple  
memory data busses.  
• Data path for read and write operations  
• Low noise 12mA TTL level outputs  
• Bidirectional 3-bus architecture: X, Y, Z  
— One CPU bus: X  
— Two (interleaved or banked) memory busses:Y & Z  
— Each bus can be independently latched  
• Byte control on all three busses  
The 73720/A uses a three bus architecture (X, Y, Z), with  
control signals suitable for simple transfer between the CPU  
bus (X) and either memory bus (Y or Z). The Bus Exchanger  
featuresindependentreadandwrite latchesforeachmemory  
bus, thus supporting a variety of memory strategies. All three  
ports support byte enable to independently enable upper and  
lower bytes.  
• Source terminated outputs for low noise and undershoot  
control  
• 68-pin PLCC and 80-pin PQFP package  
• High-performance CMOS technology.
