IDT79R3041-33J

The IDT79R3041-33J is a single-core, 32‑bit MIPS‑I microprocessor packaged in an 84‑pin PLCC. Running at 33 MHz with 5 V I/O and a commercial temperature range, it delivers a compact, integrated processing solution for cost‑sensitive embedded systems.

Designed as part of the R3041 RISController family, the device combines on‑chip caches, a multiply/divide unit, programmable bus interface and integrated DMA and timers to reduce system BOM and simplify low‑cost designs.

Key Features

• Core and Architecture  MIPS‑I RISC single core, 32‑bit datapath providing established RISC instruction set compatibility.
• Clock and Performance  Supports double‑frequency clock input and operation at 16.67 MHz, 20 MHz, 25 MHz and 33 MHz; family documentation cites 20 MIPS at 25 MHz.
• On‑chip Memory  2 KB instruction cache and 512 B data cache integrated on‑chip to reduce external memory requirements and improve access latency for embedded code and data.
• Bus and I/O Flexibility  Programmable bus interface with port width support for 8‑, 16‑ and 32‑bit memory subregions, plus programmable bus timing options for hold and turnaround control.
• Integrated Data Path Enhancements  On‑chip multiply/divide unit, 4‑deep write buffer and 4‑deep read buffer to minimize memory stalls and support burst reads/writes.
• System Integration  On‑chip DMA arbiter and a 24‑bit timer to facilitate peripheral transfers and timekeeping without additional external logic.
• Boot Flexibility  Boot support from 8‑, 16‑, or 32‑bit wide PROMs for adaptable system boot configurations.
• Package, Power and Temperature  84‑PLCC package (29.31 × 29.31 mm), surface‑mount mounting, 5 V I/O supply and commercial operating temperature range of 0 °C to 70 °C.
• Regulatory  RoHS compliant.

Typical Applications

• Embedded Controllers  Compact single‑chip processing for control tasks in consumer and industrial embedded systems where reduced BOM is important.
• Boot and System Management  Acts as a boot/master processor with support for multiple PROM bus widths and integrated timers for system initialization and management.
• Low‑Cost Networked Devices  Suitable for cost‑sensitive networked or peripheral devices that benefit from on‑chip DMA and programmable bus timing to interface with external memories and peripherals.

Unique Advantages

• Highly integrated RISC core: On‑chip caches, ALU, multiply/divide and control registers reduce external components and simplify board design.
• Flexible memory interface: Programmable 8/16/32‑bit port widths and timing support enable straightforward integration with a variety of memory configurations.
• Reduced memory stalls: Dedicated 4‑deep read and write buffers plus on‑chip DMA arbitration lower latency and offload routine transfer tasks from the CPU.
• Boot versatility: Ability to boot from multiple PROM widths makes field and manufacturing programming options more flexible.
• Consumer temperature and RoHS compliance: Commercial operating range and RoHS compatibility align the device with common consumer and embedded product requirements.
