NG80960JD3V40

The NG80960JD3V40 is an Intel i960-series embedded microprocessor in a 132-lead plastic QFP package. It features a single 32-bit core running at a 40 MHz clock rate and is targeted at general embedded systems requiring on-chip integration and deterministic instruction execution.

Designed for commercial-grade embedded applications, the device combines a 3.3 V I/O supply, DRAM controller support, on-chip memory resources and cache options to simplify system design and reduce external memory bandwidth requirements.

Key Features

• Core Architecture  Single 32-bit i960 core with one-instruction-per-clock execution as defined for the i960 J-series processors.
• Clock and Performance  Core frequency indicated as 40 MHz for this part number (NG80960JD3V40).
• Instruction and Data Cache (JD variant)  Programmable instruction cache (4 KB for JF/JD variants) and a direct-mapped data cache (2 KB for JF/JD variants) to improve code and data throughput.
• On-Chip RAM and Stack Frame Cache  Includes on-chip data RAM (1 KB) for critical variable storage and an on-chip stack frame cache that can save register sets automatically on call/return.
• Memory and Bus  High-bandwidth burst bus with 32-bit multiplexed address/data, selectable 8/16/32-bit bus widths and support for unaligned accesses and both big- and little-endian byte ordering.
• I/O and Voltage  3.3 V I/O supply with 5 V tolerant inputs and TTL-compatible outputs.
• Timers and Interrupts  Two on-chip independent 32-bit timers with prescaling and a high-speed interrupt controller offering multiple programmable priorities and maskable pins.
• Power and Temperature Range  Commercial-grade device with operating temperature range 0 °C to 100 °C and a halt mode for low-power operation.
• Package and Mounting  132-lead Plastic Quad Flat Pack (132-QFP), surface-mount mounting type.
• Compliance  RoHS compliant.

Typical Applications

• Embedded Control Systems  Single-core 32-bit processing and on-chip memory resources suit machine control, sequence management and real-time embedded controllers.
• Industrial Automation  Timer resources, interrupt priorities and DRAM controller support make the device applicable for PLCs, motion control and factory automation modules.
• Communications and Networking Equipment  High-bandwidth burst bus and selectable bus widths enable packet handling, protocol offload and peripheral interfacing in embedded communications gear.
• Consumer and Commercial Electronics  Compact 132-QFP surface-mount package and commercial temperature rating fit a range of consumer and commercial embedded products requiring moderate performance and integration.

Unique Advantages

• Deterministic Instruction Throughput: One-instruction-per-clock execution reduces instruction latency and simplifies performance budgeting for real-time designs.
• Integrated Cache and RAM: On-chip instruction/data caches and 1 KB data RAM reduce external memory dependence and improve effective program performance.
• Flexible Bus Configuration: Selectable 8/16/32-bit bus widths and a 32-bit multiplexed address/data bus support multiple memory and peripheral topologies.
• 3.3 V Operation with 5 V Tolerance: 3.3 V I/O with 5 V tolerant inputs eases interfacing with legacy TTL signals while maintaining modern supply levels.
• Compact Surface-Mount Package: 132-QFP package balances pin count and PCB footprint for space-constrained embedded designs.
• Commercial-Grade Robustness: Specified operating range of 0 °C to 100 °C and halt mode for reduced power help maintain reliable operation in typical commercial environments.
