Overview of IDT79RC32V334-133BB – IC MPU INTERPRISE 133MHZ 256BGA
The IDT79RC32V334-133BB is a single-core, 32-bit MIPS-II microprocessor operating at 133 MHz designed for embedded applications. It integrates a high-performance RC32300-based CPU core with on-chip memory and peripheral controllers to address communications, control, and general embedded processing tasks.
With an integrated SDRAM controller, DMA, serial interfaces and a compact 256-ball PBGA package, this device targets embedded system designs where integration, proven ISA compatibility and straightforward system-level interfacing are priorities.
Key Features
- Core and ISA – MIPS-II RC32300 family core implementation providing a 32-bit single core CPU running at 133 MHz.
- On-chip Memory & MMU – Includes an 8 KB instruction cache (2-way set associative) and 2 KB data cache (2-way set associative) plus an MMU with a 32-page TLB for virtual memory management.
- DMA and Bus Interfaces – Four general-purpose DMA channels with support for scatter/gather and chaining; local bus interface with 26-bit address and 32-bit data buses for direct control of local memory and peripherals.
- Memory Controllers – Integrated SDRAM controller supporting 32-bit memory and up to 512 MB total SDRAM (series-level capability noted in datasheet); memory and peripheral controller supports multiple bus widths and boot PROM.
- Peripheral Connectivity – Dual 16550-compatible UARTs (up to 1.5 Mb/s), SPI master interface and programmable I/O for flexible peripheral control and serial communications.
- Timers and System Resources – Four general-purpose 32-bit timers/counters, programmable watchdog timers and an interrupt controller for exception and timing management.
- PCI and Debug – 32-bit PCI interface (up to 66 MHz, Rev. 2.2 compatible) and EJTAG/JTAG in-circuit emulator interface for system expansion and development/debug support.
- Package & Power – 256-ball PBGA (17×17) surface-mount package; 3.3 V operation with 5 V tolerant I/O.
- Operating Range & Qualification – Consumer qualification; operating temperature range 0 °C to 70 °C. RoHS compliant.
Typical Applications
- Embedded Communications – On-chip UARTs, SPI, DMA and PCI support integrated communications protocols and I/O offload in embedded communications equipment.
- Networking & Peripheral Controllers – Local bus, SDRAM controller and PCI interface enable compact network appliance and peripheral controller designs.
- Industrial Control – Timers, watchdogs and programmable I/O provide deterministic control and monitoring for industrial embedded systems within the specified temperature range.
- System Integration & Development – EJTAG/JTAG support and standardized peripheral interfaces simplify prototyping and software bring-up for embedded platforms.
Unique Advantages
- Proven MIPS-II Architecture: Provides a widely supported 32-bit ISA for established toolchains and operating system compatibility.
- High Integration: On-chip SDRAM controller, DMA, PCI, UARTs and SPI reduce external component count and simplify board-level design.
- Flexible Memory and I/O: Support for multiple memory widths and 5 V tolerant I/O enables broader interfacing options with legacy and modern peripherals.
- Compact Surface-Mount Package: 256-ball PBGA (17×17) delivers a small form-factor solution suitable for space-constrained embedded boards.
- Development-Friendly Features: EJTAG/JTAG and 16550-compatible UARTs make software development, debugging and integration more straightforward.
