IDT79RV4640-150DU

The IDT79RV4640-150DU is a single-core MIPS-I 64-bit microprocessor offered in a 128-PQFP (28×28) surface-mount package. With a 150 MHz core frequency and 3.3 V I/O, it is targeted at embedded applications that require 64-bit integer processing in a 32-bit system environment.

Series-level design emphasizes integration, on-chip cache and DSP-capable integer multiply support, and features aimed at real-time embedded use cases such as networking, office automation and consumer multimedia devices.

Key Features

• Core & Architecture  MIPS-I 64-bit RISC core, single-core configuration with 64-bit registers and 64-bit integer operations.
• Performance  150 MHz core clock as specified for this part, delivering 64-bit processing performance in embedded systems.
• Voltage & I/O  3.3 V I/O voltage.
• On-chip Caches (series-level)  Separate instruction and data caches (8 KB each in the RC4640 family), 2-way set associative with write-back and write-through support and cache-locking options to aid deterministic response.
• DSP and Multiply Support (series-level)  High-performance integer multiply unit and DSP-capable architecture described for the RC4640 family.
• System Interface (series-level)  Designed for direct 32-bit bus interfacing to bring 64-bit processing capability into 32-bit system designs; series supports synchronized system interface and RC4000 family bus compatibility.
• Power Management (series-level)  Series-level low-power operation with active power management that can power down inactive units and provide a standby mode.
• Package & Mounting  128-PQFP (28×28) package, surface-mount mounting, supplied in tray format.
• Environmental & Qualification  RoHS compliant and consumer-qualified; specified operating temperature range 0 °C to 70 °C.

Typical Applications

• Networking Equipment  Routing and switching platforms where 64-bit processing and cache performance benefit packet handling and control-plane tasks.
• Office Automation  Printers and scanners that require embedded processing for control, data handling and interface management.
• Consumer Multimedia Systems  Embedded multimedia and game systems that leverage the family’s DSP-capable integer multiply unit and on-chip caches.

Unique Advantages

• 64-bit Processing in 32-bit Systems  A 64-bit core paired with a 32-bit system interface enables higher internal processing precision while maintaining compatibility with 32-bit system designs.
• On-chip Cache with Locking  Separate instruction and data caches with cache-locking support help deliver deterministic behavior for real-time embedded tasks.
• Series-Level DSP Capability  The RC4640 family includes a high-performance integer multiply unit and DSP-oriented pipeline features to accelerate compute-intensive routines.
• Low-Power Operation  Active power management and standby modes in the series reduce power consumption by powering down inactive units.
• Deployment-Ready Packaging  Standard 128-PQFP (28×28) surface-mount package and tray supply simplify PCB assembly and procurement for production runs.
