IDT79RC32V364-100DAG

The IDT79RC32V364-100DAG is a 32-bit MIPS32 microprocessor in a 144-TQFP (20×20) surface-mount package, manufactured by Renesas and offered as a consumer-qualified embedded MPU. The device provides a single MIPS32 core running at 100 MHz with a 3.3 V I/O domain and is suited for performance-focused consumer embedded applications requiring on-chip cache, flexible bus interfacing and low-voltage operation.

Key Features

• Core — Single MIPS32 32-bit processor core running at 100 MHz, delivering RISC-class processing suitable for embedded control and compute tasks.
• On‑chip Memory — Separate on-chip caches including an 8 kB instruction cache and a 2 kB data cache with 2‑way set associativity; supports write-back and write-through modes and per-line cache locking for deterministic behavior.
• Memory Management — On-chip MMU compatible with RC4000 and a 32-entry page TLB, providing flexible address translation and support for variable page sizes and locked entries.
• Bus Interface — Flexible, programmable bus interface supporting 8-, 16- and 32-bit memory and I/O regions, selectable bus turnaround timing, and single or burst transactions for adaptable system integration.
• Power and Supply — 3.3 V I/O operation; series documentation describes active power management and standby power modes (datasheet lists typical power and standby figures for the series).
• Development and Debug — Enhanced JTAG interface for in-circuit emulation and debug support.
• Package and Mounting — 144-TQFP (20×20) tray packaged, surface-mount device suitable for compact board layouts.
• Operating Range and Qualification — Consumer-qualified part with an operating temperature range of 0 °C to 70 °C.
• Graphics Acceleration — No integrated graphics acceleration; optimized for general-purpose embedded processing.

Typical Applications

• Consumer Embedded Devices — Control and logic tasks in consumer electronics where a 32-bit MIPS core, on-chip caches and flexible I/O width simplify system design.
• Embedded Control and Interface — User-interface controllers, protocol handlers and control subsystems that benefit from deterministic cache locking and a programmable bus interface.
• Compute-Intensive Routines — Applications that use integer multiply/add operations or algorithmic processing that take advantage of the MIPS32 instruction set and on-chip cache performance.

Unique Advantages

• Single‑chip MIPS32 Processing: Provides a full 32-bit MIPS32 core in a compact package for straightforward integration into embedded designs.
• Deterministic Cache Control: Per-line cache locking and selectable write-back/write-through modes enable predictable real-time behavior where needed.
• Flexible Memory Interface: Programmable bus widths (8/16/32-bit) and burst support reduce external glue logic and simplify interfacing to a range of memory and I/O devices.
• Compact, Surface‑mount Package: 144‑TQFP (20×20) packaging supports space-constrained PCBs while retaining broad I/O capability.
• Enhanced Debug Support: Integrated enhanced JTAG/ICE interface lowers the cost and complexity of in-circuit emulation and debugging.
• Consumer Qualification and Temperature Range: Designed for consumer-market deployments with a specified 0 °C to 70 °C operating range.
