IDT79R4700-100G

The IDT79R4700-100G is a MIPS-I architecture, 64-bit RISC microprocessor offered in a 179-pin PGA through-hole package. This consumer-grade MPU operates with 5 V I/O and runs at 100 MHz, delivering 64-bit integer and floating-point processing in a single-core configuration.

Based on the R4700 family architecture, this device suits embedded designs that require 64-bit processing, standard I/O voltage compatibility, and a socketable PGA package for prototyping or low-volume production. It is RoHS compliant and specified for operation from 0 °C to 70 °C.

Key Features

• Core and Architecture MIPS-I single core with 64-bit integer and floating-point capabilities; designed to provide 64-bit registers and 64-bit virtual address handling as part of the R4700 family architecture.
• Clock Speed 100 MHz operating frequency suitable for embedded control and data path tasks requiring deterministic performance.
• Memory Subsystem (R4700 family) Series-level features include two-way set associative caches and separate instruction/data caches (series documentation cites 16KB instruction and 16KB data caches for the R4700 family), and a flexible MMU with an associative TLB.
• Power and Voltage 5 V I/O signaling consistent with the “R” variant of the R4700 family; the series documentation also describes dynamic power management and standby modes.
• Package and Mounting 179-pin PGA supplier device package in a tube case; through-hole mounting simplifies socketing and board-level replacement.
• Operating Range and Qualification Consumer-grade device specified for 0 °C to 70 °C operation and RoHS compliant.
• Graphics and Acceleration No graphics acceleration included—focused on integer and floating-point CPU processing.

Typical Applications

• Networking Equipment Suitable for LAN switches and routers where 64-bit processing and R4700 family features (MMU, caches) support packet processing and control-plane tasks.
• Office and Production Devices Applicable to color printers and other imaging devices that benefit from 64-bit computation for raster and data handling.
• Embedded Systems Use in general embedded platforms requiring a 64-bit RISC core with 5 V I/O and a through-hole, socketable package for development or field-replaceable modules.

Unique Advantages

• 64-bit Processing Capability: Native 64-bit integer and floating-point operations enable wider data paths and larger addressable memory spaces compared to 32-bit processors.
• R4700 Family Architecture: Leverages series-level features such as set associative caches, a simple 5-stage pipeline, and a flexible MMU with associative TLB as described in the R4700 documentation.
• Standard 5 V I/O: The “R” variant’s 5 V I/O simplifies integration into legacy and mixed-voltage embedded systems.
• Socketable 179-PGA Package: Through-hole PGA format supports prototyping, testing, and module-level replacement without surface-mount assembly.
• RoHS Compliant: Meets RoHS requirements for environmental compliance in consumer applications.
• Consumer-Grade Temperature Range: Specified for 0 °C to 70 °C operation to match typical consumer and commercial embedded environments.
