IDT79RV4640-200DU

The IDT79RV4640-200DU is a single-core, 64-bit embedded microprocessor based on the MIPS-I RISC architecture, specified for 200 MHz operation and 3.3 V I/O. It provides 64-bit integer registers and a 32-bit system interface to bring 64-bit processing capability into cost-sensitive 32-bit system designs.

Designed for embedded markets, this part targets applications such as internetworking equipment, office automation and consumer multimedia systems where compact integration, on-chip caching and low-power options are important. The device ships in a 128-PQFP (28 × 28 mm) surface-mount package and is RoHS compliant.

Key Features

• Core MIPS-I single-core microprocessor with 64-bit registers and 64-bit integer operation support.
• Performance 200 MHz operating frequency (device-specific rating).
• Memory and Cache On-chip instruction and data cache architecture included in the series; separate caches enable efficient code and data handling for embedded workloads.
• System Interface 32-bit synchronized system interface for direct connection to 32-bit systems while delivering 64-bit processing capability.
• Low-Power Operation Series-level power management features include active power management to power down inactive units and a standby mode for reduced power consumption.
• Package & Mounting 128-PQFP (28 × 28 mm) surface-mount package; supplied in tray.
• Voltage & Temperature 3.3 V I/O and rated for operation from 0 °C to 70 °C.
• Compliance RoHS compliant and qualified for consumer applications.

Typical Applications

• Internetworking Equipment — Suitable for routers and switches requiring embedded control and packet-processing functions.
• Office Automation — Fits printer and scanner controller designs that need compact, integrated processing with deterministic cache behavior.
• Consumer Multimedia Systems — Appropriate for game systems and multimedia devices that benefit from 64-bit processing and on-chip caching.

Unique Advantages

• 64-bit Processing in 32-bit Systems: The 32-bit system interface brings 64-bit register and integer capabilities into cost-sensitive 32-bit implementations.
• On-chip Cache Architecture: Separate instruction and data caches improve bandwidth and responsiveness for embedded workloads.
• Power Management: Active power-down of inactive units and standby mode reduce system-level power draw when full performance is not required.
• Compact Surface-Mount Packaging: 128-PQFP (28 × 28 mm) provides a high-pin-count solution in a standard surface-mount footprint for dense board layouts.
• Series-Level Integration: The RC4640 family features a high level of integration that simplifies system design and reduces external component count.
• RoHS and Consumer Qualification: RoHS compliance and consumer qualification streamline adoption into commercial electronics products.
