NG80960JC66

The NG80960JC66 is an Intel i960-series embedded 32-bit microprocessor offered in a 132-lead PQFP package. It provides a single 32-bit core running at 66 MHz with on-chip memory structures and integrated system peripherals geared for embedded applications.

Designed for commercial embedded markets, this device emphasizes deterministic execution, integrated memory support and system-level peripherals to simplify board-level design and accelerate time-to-market.

Key Features

• Core  i960 single 32-bit core operating at 66 MHz; the i960 series supports one-instruction-per-clock execution for predictable instruction timing.
• Caches and On‑Chip RAM  JC-series cache configuration includes a 16 KB two-way set associative instruction cache and a 4 KB direct-mapped data cache; additionally the series provides 1 KB on-chip data RAM for critical variable storage.
• Memory and Bus  Integrated DRAM controller support with a high-bandwidth burst bus and selectable 8-, 16- or 32-bit bus widths for flexible memory interfacing and system configurations.
• Interrupts and Timers  High-speed interrupt controller with multiple programmable priorities and two on-chip 32-bit timers with prescaling, suitable for real-time task scheduling.
• System Integration  On-chip stack frame cache and multiple register sets for fast context switching; programmable cache-locking mechanisms and support for big- or little-endian byte ordering.
• Voltage and I/O  3.3 V supply voltage with 5 V tolerant inputs and TTL-compatible outputs, supporting common mixed-voltage system designs.
• Package and Mounting  Supplied in a 132-lead PQFP (24.13 × 24.13 mm) surface-mount package; commercial-grade device with operating temperature range of 0 °C to 100 °C.
• Debug and Test  IEEE 1149.1 (JTAG) boundary-scan compatibility for board-level test and debug.
• Graphics  No graphics acceleration—focus is on general-purpose embedded processing and control functionality.
• Compliance  RoHS-compliant.

Typical Applications

• Embedded control systems  Deterministic execution, integrated timers and robust interrupt handling make the NG80960JC66 well suited for general embedded control tasks.
• Industrial automation  On-chip caches, DRAM interface options and 5 V tolerant inputs support industrial embedded modules that require reliable processing and interface flexibility.
• Communications and networking equipment  High-bandwidth burst bus and selectable bus widths enable the device to handle packet processing and protocol offload functions in embedded networking designs.
• Instrumentation and data acquisition  Fast interrupt response and integrated timers aid deterministic data sampling and acquisition workflows.

Unique Advantages

• Deterministic single-cycle execution: One-instruction-per-clock architecture provides predictable instruction timing for real-time application scheduling.
• On-chip caches and RAM: 16 KB instruction cache, 4 KB data cache and 1 KB on-chip RAM reduce external memory dependence and improve code/data locality.
• Flexible memory interface: DRAM controller support and selectable 8/16/32-bit bus widths simplify system memory integration across a range of designs.
• Integrated system peripherals: Built-in interrupt controller and dual 32-bit timers reduce external component count and simplify firmware design for control-centric applications.
• 3.3 V operation with 5 V tolerance: Native 3.3 V supply with 5 V tolerant inputs enables compatibility with a variety of legacy I/O levels.
• Board-level testability: IEEE 1149.1 (JTAG) boundary-scan support streamlines manufacturing test and in-system debug.
