IDT79R4650-133DP

The IDT79R4650-133DP is a MIPS‑I, single‑core 64‑bit embedded microprocessor running at 133 MHz. Designed for consumer‑grade embedded applications, it pairs a 64‑bit core with on‑chip caches and a flexible system interface to deliver deterministic performance for multimedia and real‑time systems.

Key value propositions include 64‑bit integer processing, separate instruction and data caches, selectable system interface width, and active power management for reduced energy use in embedded designs.

Key Features

• Core and Performance  MIPS‑I single core with 64‑bit registers and 64‑bit integer operations running at 133 MHz.
• Memory and Caching  Separate 8 kB instruction cache and 8 kB data cache with cache locking support; internal cache bandwidth and organization optimize code and data throughput.
• Integer DSP Capability  Integrated integer multiply unit and DSP‑oriented instructions from the RC4650 family to accelerate integer multiply‑accumulate workloads.
• System Interface  Synchronized system interface compatible with 32‑bit or 64‑bit systems and a system interface bandwidth capability described in the RC4650 family documentation.
• Power Management  Active power management powers down inactive units and a standby mode reduces power during idle periods.
• Package and Mounting  208‑pin PQFP (28 × 28 mm) surface‑mount package supplied in tray format for board‑level assembly.
• Electrical and Environmental  5 V I/O signaling ("R" family indicates 5 V parts) and RoHS compliant; consumer qualification with an operating temperature range of 0°C to 70°C.
• Graphics and FP  No graphics acceleration is provided; floating‑point capabilities and other features follow the RC4650 family specification.

Typical Applications

• Consumer Game Systems  Suitable for game system control and media handling where 64‑bit integer throughput and cache performance are beneficial.
• Multimedia Devices  Useful in multimedia consumer products that benefit from on‑chip caches and integer DSP capability for data‑processing tasks.
• Embedded Control Systems  Applicable to embedded processor designs that require deterministic behavior and real‑time support available in the RC4650 family.

Unique Advantages

• 64‑Bit Processing:  64‑bit registers and data paths enable wider integer operations and data handling compared to 32‑bit cores.
• Balanced On‑Chip Caches:  Separate 8 kB instruction and 8 kB data caches with cache locking provide predictable performance and high local bandwidth.
• Flexible System Interface:  Direct interface to 32‑bit or 64‑bit systems and synchronized operation for multi‑master environments simplifies system integration.
• Power Efficiency Features:  Active power management and standby modes allow designers to reduce active power consumption in embedded deployments.
• Tray Packaging for Production:  Supplied in tray format and in a standard 208‑PQFP package for compatibility with common assembly processes.
