DESCRIPTION:
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 multiplexed address and data busses.
FEATURES:
⢠High-speed 16-bit bus exchange for interbus communication
in the following environments:
â Multi-way interleaving memory
â Multiplexed address and data busses
⢠Direct interface to R3051 family RISChipSetï
â R3051⢠family of integrated RISControllerï CPUs
â R3721 DRAM controller
⢠Data path for read and write operations
⢠Low noise 12mA TTL level outputs
⢠Bidirectional 3-bus architecture: X, Y, Z
â One CPU bus: X
â Two (interleaved or banked) memory busses:Y & Z
â Each bus can be independently latched
⢠Byte control on all three busses
⢠Source terminated outputs for low noise and undershoot
control
⢠68-pin PLCC and 80-pin PQFP package
⢠High-performance CMOS technology.
