Overview of IDT79R4700-133G – MIPS‑I 64‑Bit 133MHz Microprocessor (179‑PGA)
The IDT79R4700-133G is a single‑core, 64‑bit MIPS‑I microprocessor operating at 133 MHz, supplied in a 179‑pin PGA package. Designed for embedded applications, it delivers 64‑bit integer and floating‑point capabilities plus an integrated memory management structure to address complex embedded workloads.
With a 5 V I/O voltage and through‑hole 179‑PGA mounting, this consumer‑qualified, RoHS‑compliant device is targeted at embedded networking, printing, and similar systems that require 64‑bit processing, deterministic performance and established development support.
Key Features
- Core & Architecture True 64‑bit MIPS‑I core providing 64‑bit integer operations, 64‑bit floating‑point operations, and 64‑bit registers.
- Clock Speed Fixed 133 MHz operating frequency for predictable embedded performance.
- Memory & MMU Integrated memory management features from the R4700 family including a flexible MMU and fully associative TLB architecture (as documented for the series).
- Caches & Pipeline Series architecture includes two‑way set associative instruction and data caches and a simple 5‑stage pipeline for efficient instruction throughput.
- Floating‑Point Unit On‑chip 64‑bit floating‑point support for compute and signal processing tasks (as part of the R4700 series feature set).
- Power 5 V I/O operation consistent with the R‑variant product family; series documentation describes dynamic power management and standby modes.
- Package & Mounting Supplier device package: 179‑PGA in tube packaging; designed for through‑hole mounting.
- Operating Range & Qualification Consumer qualification with an operating temperature range of 0 °C to 70 °C; RoHS‑compliant.
Typical Applications
- LAN Switches and Routers Leverage 64‑bit processing and integrated MMU features for packet handling, forwarding algorithms, and control‑plane tasks.
- Color Printers and Imaging Devices Use on‑chip floating‑point and integer performance for image processing, rasterization, and device control functions.
- General Embedded Systems Suitable for embedded controllers and appliances that require 64‑bit compute resources and deterministic clocked operation at 133 MHz.
Unique Advantages
- 64‑Bit Processing Capability: Enables both 64‑bit integer and floating‑point operations and a 64‑bit virtual address space for memory‑intensive embedded tasks.
- Established R4700 Family Architecture: Series design provides a proven microarchitecture with two‑way set associative caches, a 5‑stage pipeline and an integrated MMU/TLB.
