NG80960JD3V66

The NG80960JD3V66 is an Intel i960-series embedded microprocessor packaged in a 132-lead QFP for surface-mount assembly. It implements a single 32-bit core operating at 66 MHz and targets embedded applications that require deterministic instruction throughput, integrated memory support and a compact package footprint.

Built on the i960 architecture, the device combines single-instruction-per-clock execution with on-chip caches, on-chip RAM and an interrupt/timer subsystem to streamline real-time and control-focused system designs.

Key Features

• Core and Architecture Single 32‑bit i960 core with one-instruction-per-clock execution and a load/store programming model for predictable performance.
• Clock Rate 66 MHz core clock as specified for the NG80960JD3V66 variant, providing consistent execution timing for embedded control tasks.
• Instruction and Data Cache Two-way set-associative instruction cache (JD variant: 4 KB) and direct-mapped data cache (JD variant: 2 KB) to reduce external memory accesses and improve code/data locality.
• On‑Chip Memory 1 KB on-chip data RAM for critical variable storage with single-cycle access.
• Interfaces and Bus High-bandwidth burst bus with 32‑bit multiplexed address/data and selectable 8/16/32-bit external bus widths; supports unaligned accesses and both big- and little-endian byte ordering.
• Interrupts and Timers High-speed interrupt controller with up to 31 programmable priorities and two on-chip 32‑bit timers with clock prescaling options.
• Power and I/O 3.3 V supply with 5 V tolerant inputs and TTL-compatible outputs for mixed-voltage interfacing; includes a halt mode for low-power operation.
• Package and Mounting 132-lead Plastic Quad Flat Pack (132‑QFP) for surface-mount assembly, simplifying board layout in space-constrained systems.
• Operating Range and Compliance Commercial grade operation from 0 °C to 100 °C and RoHS compliant.
• Debug and Test IEEE 1149.1 (JTAG) boundary-scan compatibility for board-level test and debugging.

Typical Applications

• Industrial Control — Deterministic execution, on-chip timers and robust interrupt handling make the NG80960JD3V66 suitable for PLCs, motion control and machine automation controllers.
• Communications Equipment — High-bandwidth burst bus and selectable external bus widths support packet processing and embedded protocol handling in network devices.
• Instrumentation and Test — On-chip RAM and caches plus precise interrupt/timer resources support real-time data acquisition and instrument control functions.
• Embedded Appliances — Compact 132‑QFP package and mixed-voltage I/O capability enable integration into consumer and commercial embedded appliances that require 32-bit performance.

Unique Advantages

• Predictable Execution Efficiency: One-instruction-per-clock architecture at 66 MHz simplifies timing analysis and real-time scheduling.
• Integrated Memory Hierarchy: Combined instruction and data caches plus 1 KB on-chip RAM reduce external memory bandwidth needs and improve system responsiveness.
• Flexible I/O Voltage Support: 3.3 V supply with 5 V tolerant inputs and TTL-compatible outputs eases interfacing with legacy and mixed-voltage peripherals.
• Compact Surface-Mount Package: 132‑QFP packaging supports dense board layouts while maintaining access to a broad pinout for system functions.
• Embedded System Friendliness: Programmable interrupt priorities, multiple timers and boundary-scan support simplify development and in-field diagnostics.
• Compliance and Commercial Temperature Range: RoHS compliant and specified for 0 °C to 100 °C operation for commercial deployments.
