FC80960HA40SL2GW

The FC80960HA40SL2GW is a single-core, 32-bit i960-series microprocessor in a 208‑pin PQFP package, designed for embedded system applications. At a 40 MHz bus clock the device provides a balanced combination of on-chip processing, memory and system peripherals suitable for control and real-time embedded designs.

Built around the i960 superscalar architecture, the device integrates caches, internal RAM, an FPU and an advanced interrupt/timer subsystem to deliver measurable system integration and deterministic I/O performance in commercial-temperature environments.

Key Features

• Core & Architecture 32-bit superscalar i960 core with load/store architecture. Includes sixteen 32-bit global registers and sixteen 32-bit local registers plus an on‑chip register cache for efficient context handling.
• Performance 40 MHz operating speed; series-level capability to issue up to 150 million instructions per second. External bandwidth at 40 MHz supports up to 160 Mbyte/s.
• Memory & Cache High-performance on‑chip storage with a 16 Kbyte four‑way set‑associative instruction cache, an 8 Kbyte four‑way set‑associative data cache and 2 Kbyte general purpose RAM. Supports DRAM controllers and per‑byte parity generation/checking.
• Floating Point & Coprocessor Integrated floating point unit (FPU) to accelerate arithmetic and DSP-style computations without external coprocessors.
• Interrupts & Timers High-speed interrupt controller supporting up to 240 external interrupts, 31 programmable priorities and a non‑maskable interrupt pin. Dual on‑chip 32‑bit timers with auto-reload and one‑shot modes, plus CLKIN prescaling.
• System Interfaces & Bus 32‑bit demultiplexed burst bus with support for 8/16/32‑bit external bus widths, address pipelining option and a fully programmable wait‑state generator. JTAG support (IEEE 1149.1) for debug and boundary scan.
• Power & I/O 3.3 V supply voltage with 5 V tolerant inputs and TTL‑compatible outputs, enabling flexible interfacing with mixed-voltage peripherals.
• Package & Temperature Range 208‑pin PQFP surface-mount package, commercial grade with an operating temperature range of 0 °C to 85 °C.

Typical Applications

• Embedded control systems — Leverage the 32‑bit core, integrated timers and high interrupt count for deterministic control tasks and device management.
• Real‑time data processing — Use the integrated FPU, caches and on‑chip RAM to accelerate numeric and streaming workloads that require predictable throughput.
• Systems requiring robust memory protection — The guarded memory unit supports user/supervisor read/write/execute controls and per‑byte parity checking for improved runtime protection.

Unique Advantages

• Highly integrated on‑chip resources: Instruction/data caches, general RAM and an integrated FPU reduce external component count and simplify board design.
• Deterministic embedded performance: 40 MHz operation with high external bandwidth and programmable wait states provides repeatable throughput for time‑sensitive tasks.
• Extensive interrupt and timer support: Large external interrupt capacity and dual 32‑bit timers enable responsive event handling and complex scheduling.
• Flexible system interfacing: 5 V tolerant inputs, TTL outputs and support for multiple external bus widths ease integration with a range of peripherals and legacy devices.
• Built‑in system protection and diagnostics: Guarded memory, per‑byte parity and JTAG IEEE 1149.1 support enhance reliability and simplify validation.
