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

–

Standby mode reduces internal power

◆

Fully software & pin-compatible with 40XX Processor Family

Available in 179-pin PGA or 208-pin QFP

◆
