IDT79RV4640-180DU

The IDT79RV4640-180DU is a 64‑bit embedded microprocessor IC implementing the MIPS-I architecture with a single core running at 180 MHz. It targets cost-sensitive embedded applications where 64‑bit integer processing and on‑chip performance features are required in a 3.3 V I/O, surface‑mount package.

Designed for embedded markets such as networking, office automation and consumer multimedia, the device combines a MIPS RISC core with on‑chip cache and DSP‑oriented integer/floating capabilities described in the RC4640 family datasheet to deliver an integrated, deterministic processing element in a 128‑lead PQFP (28×28 mm) package.

Key Features

• Core and Architecture  MIPS‑I single core, 64‑bit processor architecture for wide‑word integer operations.
• Clock Speed  180 MHz operating frequency as specified for this part number.
• Memory and Cache  Series documentation describes separate on‑chip caches (8 KB instruction and 8 KB data) with 2‑set associativity, write‑back and write‑through support and cache locking to help achieve deterministic response.
• DSP and Math Support  RC4640 family features include high‑performance integer multiply and floating‑point units included in the series architecture for DSP‑oriented compute tasks.
• System Interface  32‑bit system bus interface that enables integration into 32‑bit systems while leveraging 64‑bit internal processing capabilities.
• Power and Voltage  3.3 V I/O; series documentation notes power management capabilities including active unit power‑down and standby modes.
• Package and Mounting  128‑PQFP (28×28 mm) tray package, surface mount.
• Operating Range and Qualification  Consumer qualification with an operating temperature range of 0 °C to 70 °C.
• Environmental Compliance  RoHS compliant.

Typical Applications

• Networking Equipment  Routers and switches leveraging 64‑bit processing and on‑chip cache to handle packet processing and control-plane tasks.
• Office Automation  Printers and scanners requiring embedded control, data handling and deterministic cache behavior for predictable operation.
• Consumer Multimedia  Game systems and multimedia devices that benefit from integrated integer and floating‑point processing capability in a compact PQFP package.

Unique Advantages

• 64‑Bit Processing with 32‑Bit System Compatibility: Internal 64‑bit datapath and registers with a 32‑bit system bus interface allow broader system integration while maintaining wide‑word compute capability.
• On‑Chip Cache with Locking: Separate instruction and data caches with cache‑locking support help enable deterministic response for real‑time embedded tasks.
• DSP‑Oriented Arithmetic Units: Integer multiply and floating‑point units in the series architecture provide higher compute throughput for signal processing and math‑heavy routines.
• Power Management Features: Active power management and standby modes described for the family reduce power consumption of unused units to help optimize system-level power.
• Surface‑Mount PQFP Packaging: 128‑pin PQFP (28×28) facilitates compact board layouts while supporting standard surface‑mount assembly processes.
• Regulatory and Environmental Compliance: RoHS compliance supports environmental and manufacturing requirements.
