IDT79R3041-33PFG

The IDT79R3041-33PFG is a single-core, 32‑bit MIPS‑I microprocessor in the IDT RISController family, operating at 33 MHz. It is designed for embedded, low-cost systems where a compact, highly integrated RISC CPU with on-chip peripherals and flexible bus options is required.

With on-chip instruction and data caches, programmable bus-width support and a standard 100‑TQFP (14×14) surface-mount package, the device targets consumer and general embedded applications that benefit from simplified system design and reduced component count.

Key Features

• Core – MIPS‑I 32‑bit single core CPU running at 33 MHz, providing a familiar RISC instruction set and integrated integer execution units.
• Caches and Buffers – On‑chip caches include a 2 KB instruction cache and 512 B data cache; integrated 4‑deep write buffer and 4‑word read buffer help reduce memory stalls.
• On‑chip Peripherals – Integrated multiply/divide unit, DMA arbiter and a 24‑bit timer are provided on chip to reduce external component requirements.
• Flexible Bus Interface – Programmable port‑width support (8‑, 16‑, and 32‑bit memory sub‑regions) and programmable bus timing (address hold, turnaround, read/write masks) enable simple, low‑cost memory and peripheral interfacing.
• Boot Options – Supports boot from 8‑, 16‑ or 32‑bit wide PROMs for flexible system boot configurations.
• Clock and Performance Modes – Double‑frequency clock input and support for multiple operating clock points including 33 MHz.
• Voltage and Mounting – 5 V I/O and surface‑mount 100‑TQFP (14×14) supplier device package; supplied in tray packaging.
• Operating Range and Compliance – Commercial temperature range 0 °C to 70 °C and RoHS compliant.

Typical Applications

• Consumer Electronics – Control and user‑interface processing in consumer devices where a compact, single‑chip RISC controller reduces system cost.
• Low‑Cost Embedded Systems – General embedded controllers and appliances that benefit from integrated caches, DMA arbitration and programmable bus interfacing.
• PROM‑Booted Devices – Systems that require booting from 8‑, 16‑ or 32‑bit PROMs for straightforward firmware deployment.

Unique Advantages

• Highly integrated architecture: On‑chip CPU, caches, multiply/divide unit, DMA arbiter and timer reduce external components and simplify PCB design.
• Flexible memory interfacing: Programmable port widths and bus timing allow direct connection to a variety of memory widths and timing requirements without complex glue logic.
• Cache and buffer support: Instruction and data caches plus read/write buffers minimize memory latency and improve sustained data throughput for embedded workloads.
• Standard package and mounting: 100‑TQFP (14×14) surface‑mount package in tray format supports common assembly processes and board layouts.
• Commercial temperature and RoHS compliance: Suitable for consumer and general embedded products with a 0 °C to 70 °C operating range and RoHS conformant materials.
• Family compatibility and software ecosystem: Part of the RISController family with documented software support including compilers, RTOSs, debuggers and emulation libraries to accelerate development.
