IDT79RC32V364-133DAG

The IDT79RC32V364-133DAG is a single-core, 32-bit MIPS32 microprocessor running at 133 MHz in a 144-TQFP (20×20) surface‑mount package. Designed for embedded and consumer applications, it delivers integrated on-chip caches, a flexible bus interface and a hardware MMU to support performance-sensitive, cost-conscious designs.

With 3.3 V operation and RoHS compliance, the device targets embedded controllers and compact systems where predictable performance, low-power modes and software compatibility across the RISController family are important.

Key Features

• Core and Performance — MIPS32 32-bit CPU core, single core, operating at 133 MHz.
• On-chip Caches — Separate 8 kB instruction cache and 2 kB data cache with 2‑way set associative architecture and optional per-line cache locking for deterministic behavior.
• Memory Management — Integrated MMU with a 32‑page TLB and support for variable page size and locked entries, enabling efficient address translation without performance penalty.
• Bus Interface — Programmable port-width interface (8-, 16-, 32-bit memory and I/O regions), configurable bus turnaround times and support for single or burst transactions to simplify low-cost board designs.
• Power Management — Active power management with typical power around 700 mW at 133 MHz and standby mode under 300 mW, enabling reduced system power in idle states.
• Debug and Test — Enhanced JTAG interface suitable for in-circuit emulation and debugging.
• Electrical and Mechanical — 3.3 V core and I/O operation; supplied in 144‑TQFP (20×20) package, tray packaging, surface-mount mounting type.
• Environmental and Qualification — Consumer qualification and RoHS compliant; specified operating temperature range 0 °C to 70 °C.

Typical Applications

• Embedded Controllers — Control units and appliance controllers that benefit from a compact 144‑TQFP package and integrated MMU for deterministic memory management.
• Consumer Electronics — Cost-sensitive consumer devices requiring a 32-bit MIPS32 core at 133 MHz with on-chip caches and low‑power modes.
• Low-cost Networking/Peripherals — Networked appliances and peripheral controllers that need a flexible bus interface (8/16/32‑bit) and burst transaction support for efficient I/O.

Unique Advantages

• Software Compatibility Across the Series: Based on the RISController architecture and MIPS32 instruction set, enabling application portability within the RISController family.
• Deterministic Cache Control: Per-line cache locking and separate instruction/data caches help achieve predictable timing for real‑time embedded tasks.
• Flexible Memory Interface: Programmable port widths and bus timing options simplify integration with a variety of memory and I/O devices, reducing board-level complexity.
• On-chip MMU: A 32‑page TLB with variable page size supports advanced memory management without external components.
• Power-aware Design: Active power management and a low standby power state allow designers to optimize energy use in battery‑sensitive or always‑on systems.
• Compact, Industry-standard Package: 144‑TQFP (20×20) surface-mount package supports dense PCB layouts and automated assembly.
