IDT79R3041-25PF

The IDT79R3041-25PF is a 32-bit MIPS‑I microprocessor in a 100‑pin TQFP (14×14 mm) surface‑mount package, offered by Renesas as part of the IDT79R3041 series. Built for consumer-grade embedded systems, this single‑core MPU runs at 25 MHz and combines a compact footprint with on‑chip integration to simplify low‑cost system designs.

Designed to support embedded control and firmware‑based applications, the device delivers a balance of processing capability and integration—featuring on‑chip caches, arithmetic units, bus programmability and DMA support to reduce external component count and system complexity.

Key Features

• Core: MIPS‑I single 32‑bit core operating at 25 MHz, delivering deterministic embedded processing for control and firmware tasks.
• On‑chip Caches & ALU: 2 KB instruction cache and 512 B data cache combined with an integrated multiply/divide unit reduce dependence on external memory and accelerate compute operations.
• Bus & Memory Interface: Programmable bus interface supporting 8‑, 16‑ and 32‑bit memory sub‑regions and programmable timing (address hold, bus turnaround, read/write masks) for flexible memory and PROM boot configurations.
• Buffers & DMA: On‑chip 4‑deep write buffer and 4‑word read buffer minimize memory stalls; integrated DMA arbiter simplifies peripheral data transfers.
• Boot & Timers: Boot capability from 8‑, 16‑ or 32‑bit PROMs and an on‑chip 24‑bit timer for bootstrapping and timing tasks.
• Clocking & Performance: Supports double‑frequency clock input and series operation points including 25 MHz; documented capability of 20 MIPS at 25 MHz for performance planning.
• Package & Mounting: 100‑TQFP (14×14 mm) surface‑mount package supplied in tray format for PCB assembly.
• Electrical & Environmental: 5 V I/O voltage and commercial operating temperature range 0 °C to 70 °C; RoHS compliant and qualified for consumer applications.
• Graphics Acceleration: No graphics acceleration—focused on integer RISC processing and system control functions.

Typical Applications

• Consumer Embedded Control: Control and firmware tasks in consumer devices where a compact, single‑core 32‑bit MPU and on‑chip peripherals reduce system BOM and complexity.
• Low‑Cost Systems: Cost‑sensitive embedded systems that benefit from on‑chip caches, DMA arbitration and programmable bus timing to minimize external memory and glue logic.
• Bootloader‑Driven Devices: Systems that require PROM‑based boot from 8‑, 16‑ or 32‑bit memories, enabling simple firmware loading and updates.
• Real‑Time Control: Applications needing deterministic integer performance and on‑chip timers for scheduling and control functions.

Unique Advantages

• Highly integrated RISC core: MIPS‑I architecture with on‑chip multiply/divide and caches reduces external component needs and board space.
• Flexible memory interface: Programmable port widths (8/16/32‑bit) and timing options ease integration with a variety of PROMs and memory devices.
• Reduced memory stalls: On‑chip read/write buffers and DMA arbiter lower latency and simplify high‑throughput data transfers.
• Compact surface‑mount package: 100‑TQFP (14×14 mm) enables high‑density PCB implementations while remaining assembly‑friendly.
• Consumer‑grade qualification and RoHS compliance: Suited to commercial consumer products with environmental compliance for manufacturing.
• Simplified system design: On‑chip timer and boot options streamline firmware development and system bring‑up.

Why Choose IDT79R3041-25PF?

The IDT79R3041-25PF positions itself as a compact, integrated 32‑bit MIPS‑I MPU for consumer and low‑cost embedded systems where board space, BOM reduction and predictable integer performance matter. Its on‑chip caches, arithmetic unit, DMA arbitration and flexible bus interface combine to simplify memory architecture and speed system integration.

This part is well suited to designers building firmware‑centric devices that require PROM boot capability, deterministic control timing, and standard 5 V I/O interfacing within a commercial temperature range. RoHS compliance and a surface‑mount 100‑TQFP package support modern assembly flows and regulatory needs.
