IDT79RC32V364-100DA

The IDT79RC32V364-100DA is a single-core, 32-bit MIPS32 microprocessor running at 100 MHz in a 144-pin TQFP (20 × 20 mm) surface-mount package. It targets a variety of performance-oriented, cost-sensitive embedded applications and combines a compact package with on-chip architectural features intended to simplify system design.

Designed within the IDT79RC32V364 series, the device emphasizes efficient on-chip memory, a flexible bus and MMU, and single-supply 3.3 V operation for straightforward integration into consumer embedded systems.

Key Features

• Core MIPS32 32-bit processor core with a single execution core operating at 100 MHz; based on the RISCore32300 architecture and featuring a scalar 5-stage pipeline for streamlined instruction flow.
• On-chip Cache Separate on-chip caches with an 8 KB instruction cache and a 2 KB data cache, both 2-way set associative. Supports write-back and write-through modes and per-line cache locking for deterministic behavior.
• Memory Management & MMU Integrated RC4000-compatible MMU with an on-chip TLB (32-page entries) and support for variable page sizes and locked entries to aid address translation and real-time control.
• Bus Interface Flexible bus interface with programmable port widths (8/16/32-bit) and programmable bus turnaround for compatibility with a range of memory and I/O configurations.
• Power and Voltage Single-supply 3.3 V operation for core and I/O simplifies power design; device documentation for the series highlights low-power operation features and active power management at the device level.
• Debug and Real-time Support Enhanced JTAG (ICE) interface for in-circuit emulation and fast interrupt decode for improved real-time responsiveness.
• Package & Mounting 144-TQFP (20 × 20 mm) surface-mount package supplied in tray format for PCB assembly and compact system layouts.
• Qualification & Compliance Consumer qualification with RoHS-compliant materials; specified operating temperature range 0 °C to 70 °C.
• Graphics No graphics acceleration—focused on CPU and system control tasks rather than graphics processing.

Typical Applications

• Embedded Control Suited to control and system-processing tasks in embedded devices where a single 32-bit core and deterministic cache behavior are required.
• Consumer Electronics Consumer-grade qualification and 3.3 V operation make the part suitable for a range of consumer electronic products that need a compact MPU solution.
• Low-power Embedded Designs Series-level low-power features and single-supply operation benefit battery-aware or power-sensitive embedded applications.

Unique Advantages

• Software continuity: Based on MIPS32/RISCore32300 architecture, the series supports software compatibility across RISController devices, aiding long-term software reuse.
• Deterministic on-chip caches: Per-line cache locking and configurable write modes enable predictable performance for real-time tasks.
• Flexible memory interface: Programmable port widths and bus timing reduce external logic requirements and ease integration with varied memory and I/O devices.
• Compact surface-mount package: 144-TQFP (20×20) provides a high-pin-count solution in a space-efficient footprint for dense PCB layouts.
• Single-supply design: 3.3 V core and I/O simplifies power architecture and reduces the need for multiple regulators.
• RoHS compliant: Meets RoHS requirements for materials compliance in consumer production environments.
