IDT79RC32V334-100BBGI

The IDT79RC32V334-100BBGI is a single-core, 32-bit Interprise™ microprocessor based on the MIPS-II architecture, rated for 100 MHz operation. Designed for embedded systems, the device combines a high-performance CPU core with integrated memory and peripheral controllers to support communications, networking, and industrial control applications.

Key production-ready attributes include 3.3 V I/O with 5 V tolerant inputs, industrial temperature qualification (-40 °C to 85 °C), and a compact 256-ball PBGA (17×17) surface-mount package.

Key Features

• Core and ISA  Enhanced MIPS-II instruction set architecture providing a single 32‑bit core optimized for embedded processing and communications tasks.
• On-chip Cache and MMU  8 kB instruction cache (2‑way) and 2 kB data cache (2‑way) with cache locking and a MMU featuring a 32‑page TLB for memory protection and virtual memory management.
• Memory Subsystem  Integrated SDRAM controller capable of direct control of discrete or DIMM memories and support for up to 512 MB SDRAM device depths as described in the series documentation.
• DMA and Bus Interfaces  Multiple DMA channels with scatter/gather and chaining support, plus a 32‑bit PCI interface (series-level feature) for high-throughput peripheral and bus connectivity.
• Peripheral Interfaces  Serial interfaces including SPI master and two 16550-compatible UARTs, plus programmable I/O and timer/counter resources for flexible control and communications.
• System Integration  On-chip interrupt controller, programmable system watchdog timers, and EJTAG in-circuit emulator support for development and robust exception management.
• Power and Packaging  3.3 V operation with 5 V tolerant I/O, surface-mount 256-ball PBGA (17×17) package for compact board-level integration.
• Industrial Qualification  Operating temperature range of -40 °C to 85 °C suitable for industrial embedded applications.

Typical Applications

• Embedded Communications and Networking  Use the integrated CPU core, DMA, PCI-capable bus, and serial interfaces to implement protocol handling, packet processing, and peripheral bridging.
• Industrial Control and Automation  Industrial temperature rating and deterministic I/O make the device suitable for machine control, data acquisition, and field controllers.
• Storage and Memory-Controlled Systems  On-chip SDRAM controller and DMA support facilitate designs that require direct memory access and external memory management.
• System Controllers and Embedded Hosts  Programmable I/O, timers, UARTs and SPI support supervisory control, bootloaders, and management functions in embedded platforms.

Unique Advantages

• Highly integrated architecture: Combines a MIPS-II core with cache, MMU, SDRAM control and peripheral interfaces to reduce external component counts and simplify system design.
• Industrial operating range: Rated from -40 °C to 85 °C for reliable operation in demanding environments.
• Flexible memory and DMA support: On-chip SDRAM controller plus DMA with scatter/gather and chaining enables efficient movement of large data sets with low CPU overhead.
• Standard 3.3 V I/O with 5 V tolerance: Simplifies interfacing to legacy 5 V systems while maintaining modern 3.3 V logic levels.
• Compact surface-mount package: 256-ball PBGA (17×17) provides a small footprint for space-constrained boards while supporting robust pinout density.
• Rich peripheral set for communications: SPI, dual UARTs, programmable I/O, timers and interrupt controller support versatile device connectivity and control.
