IDT79R3041-20PFG

The IDT79R3041-20PFG is a single-core, 32-bit MIPS-I microprocessor packaged in a 100-TQFP (14×14) surface-mount package. Designed for consumer and embedded applications, it delivers a balanced combination of on-chip integration and predictable performance at a 20 MHz operating frequency.

Built for low-cost, space-constrained systems, the device includes on-chip caches, programmable bus/interface support and integrated system control features that simplify board-level design and firmware boot options.

Key Features

• Core MIPS-I architecture, single 32-bit core provides RISC-based integer processing suitable for embedded control tasks.
• Clock / Performance Specified for 20 MHz operation; supports the device’s intended embedded performance envelope.
• On‑chip Memory Includes on-chip instruction and data caches as defined for the R3041 family (2 KB instruction cache, 512 B data cache) to reduce external memory requirements and improve code/data access latency.
• Integrated System Blocks Family-level integration includes multiply/divide unit, programmable bus interface with 8/16/32-bit port-width support, on-chip DMA arbitration, and a 24-bit timer—features that reduce BOM and simplify system design.
• Bus and I/O Programmable bus timing and port-width support accommodate a range of memory sub-regions and boot-from-PROM configurations (8-, 16-, or 32-bit wide), enabling flexible memory interfacing.
• Buffers and Throughput On-chip 4-deep write buffer and 4-word read buffer support burst and block read/write patterns to minimize memory stalls.
• Power and Packaging 5 V I/O signaling and surface-mount 100-TQFP (14×14) package in tray format simplify integration into existing designs.
• Environmental / Qualification Consumer qualification with an operating temperature range of 0°C to 70°C and RoHS compliance.

Typical Applications

• Consumer Embedded Systems — Control and processing in consumer electronic devices that benefit from an integrated 32-bit RISC core and on-chip peripherals.
• Low-Cost Control Appliances — Appliance controllers and compact devices where reduced external memory and peripheral counts lower BOM and board area.
• Firmware-Driven Products — Systems that boot from PROM (8/16/32-bit) and require predictable boot and bus behavior.
• Legacy 5 V Systems — Designs that rely on 5 V I/O signaling and surface-mount TQFP packaging for straightforward board-level replacement or upgrades.

Unique Advantages

• Highly integrated RISC solution: On-chip caches, DMA arbitration, multiply/divide unit and timer reduce the need for external components and simplify system architecture.
• Flexible memory interfacing: Programmable port-width and bus timing support enable compatibility with 8-, 16-, and 32-bit memory regions and various PROM boot widths.
• Reduced memory stalls: Built-in read and write buffers support burst/block transfers to improve effective throughput with external memory.
• Compact surface-mount package: 100-TQFP (14×14) package provides a small footprint for compact board designs while supporting tray format handling.
• Consumer-grade qualification and RoHS compliance: Designed for consumer applications with an operating range of 0°C to 70°C and RoHS-compliant materials.
• 5 V I/O compatibility: Native 5 V I/O signaling eases integration into existing 5 V embedded platforms.
