FC80960HA33SL2GV

The FC80960HA33SL2GV is a 32-bit Intel i960 HA-series superscalar microprocessor offered in a 208-pin PQFP surface-mount package. It implements a single i960 core running at 33 MHz with an integrated FPU and on-chip memory/cache resources targeted at embedded system designs.

Designed for embedded applications requiring deterministic interrupt handling and on-chip peripherals, the device delivers integrated caches, internal RAM and a flexible external bus while operating from a 3.3 V I/O supply and a commercial temperature range of 0 °C to 85 °C. The part is RoHS compliant.

Key Features

• Core Architecture — 32-bit i960 superscalar processor with a single core and dedicated 16 global + 16 local register sets for parallel, load/store style execution. The HA family supports high instruction throughput as detailed in the series documentation.
• On-Chip Memory & Cache — Four-way set-associative instruction cache (16 KB), four-way set-associative data cache (8 KB) and 2 KB general purpose RAM plus on-chip register cache for reduced external memory dependence.
• Floating-Point Support — Integrated FPU to accelerate floating-point computations within the processor core.
• Bus & External Memory Support — 32-bit demultiplexed burst bus with per-byte parity generation/checking, address pipelining option and support for 8‑, 16‑ or 32‑bit external bus widths; series documentation cites up to 160 MB/s external bandwidth at 40 MHz.
• Interrupts & Timers — High-speed interrupt controller supporting a large number of external interrupts with programmable priorities and a separate non-maskable interrupt pin, plus dual on-chip 32-bit timers with auto-reload and one-shot modes.
• Power & I/O — 3.3 V I/O supply voltage with 5 V tolerant inputs and TTL-compatible outputs as specified for the HA series.
• Package & Environmental — 208-pin PQFP (surface mount) package; commercial operating temperature range 0 °C to 85 °C; RoHS compliant.

Typical Applications

• Industrial Control — Deterministic interrupt handling and dual 32-bit timers make the device suitable for motor control, PLCs and embedded control loops.
• Networking & Communications — 32-bit burst bus and on-chip caches support control-plane processing and protocol handling in communications equipment.
• Instrumentation & Test Equipment — Integrated FPU, on-chip RAM and precise timers provide the compute and timing resources needed for measurement and data acquisition systems.
• Embedded System Controllers — General-purpose embedded applications that require a 32-bit superscalar core, on-chip memory and a compact 208‑pin surface-mount package.

Unique Advantages

• Superscalar 32‑bit core: Parallel architecture and register cache improve instruction throughput for compute-intensive embedded tasks.
• Integrated memory hierarchy: On-chip instruction/data caches and general-purpose RAM reduce external memory bandwidth requirements and simplify board-level design.
• Integrated floating-point unit: On-chip FPU accelerates numeric workloads and reduces the need for external co-processors.
• Flexible external interface: Demultiplexed burst bus with selectable bus widths and parity support enables integration with a variety of external memory and peripheral configurations.
• Embedded-friendly peripherals: High-speed interrupt controller and dual 32-bit timers provide deterministic control and scheduling for real-time embedded applications.
• Industry-standard packaging and compliance: 208‑pin PQFP surface-mount package with RoHS compliance and commercial temperature rating for mainstream embedded deployments.
