Description  
◆
The IDT79R4700 64-bit RISC Microprocessor is both software and  
pin-compatible with the R4XXX processor family. With 64-bit processing  
capabilities, the R4700 provides more computational power and data  
movement bandwidth than is delivered to typical embedded systems by  
32-bit processors.  
High level of integration  
–
64-bit, 200 MHz integer CPU  
64-bit floating-point unit  
16KB instruction cache  
16KB data cache  
Flexible MMU with large, fully associative TLB  
–

The R4700 is upwardly software compatible with the IDT79R3000™  
microprocessor family, including the IDTRISController™ 79R3051™,  
R3052™, R3041™, R3081™ as well as the R4640™, R4650™, RC64474/  
475™ and R5000™. An array of development tools facilitates rapid  
development of R4700-based systems, allowing a variety of customers  
access to the MIPS Open Architecture philosophy.  
◆
Low-power operation  
–
3.3V power supply, for the “RV” part  
5V power supply, for the “R” part  
Dynamic power management
