TD8086

The TD8086 is an Intel i8086-series microprocessor in a 40-pin ceramic dual in-line package (40‑CDIP). It implements a single 16-bit core running at 5 MHz with 5 V I/O and is supplied for commercial-grade embedded applications.

Designed for embedded and system-repair use, the TD8086 provides a straightforward, through-hole 40‑CDIP form factor and supports an external 8087 floating-point coprocessor for designs that require optional numeric acceleration.

Key Features

• Core  The i8086 16‑bit single-core microprocessor architecture running at 5 MHz.
• Clock Speed  5 MHz operating frequency suitable for modest-performance embedded tasks.
• Voltage I/O  5 V I/O voltage for compatibility with standard 5 V logic levels.
• Coprocessor Support  External 8087 floating-point unit (FPU) compatibility for optional floating-point acceleration.
• Package & Mounting  40‑CDIP package supplied for through-hole mounting and straightforward board-level replacement or prototyping.
• Operating Grade & Temperature  Commercial grade with an operating temperature range of 0 °C to 70 °C.
• Environmental Compliance  RoHS compliant.

Typical Applications

• Embedded control systems  Use the TD8086 where a 16‑bit single-core processor at 5 MHz meets system control and I/O coordination needs.
• Legacy system maintenance  Direct replacement or refurbishment of through‑hole boards that require a 40‑CDIP i8086 processor.
• Prototyping and education  Through‑hole 40‑CDIP packaging and 5 V I/O facilitate hands-on prototyping and instructional projects targeting embedded processor fundamentals.

Unique Advantages

• Direct 5 V logic compatibility: 5 V I/O simplifies interfacing with existing 5 V peripheral and bus designs.
• Through‑hole 40‑CDIP package: Eases soldering, board-level replacement, and prototype experimentation without surface-mount tooling.
• Optional floating-point acceleration: Compatibility with the external 8087 FPU enables offloading of floating-point operations when required.
• Commercial temperature suitability: Rated for 0 °C to 70 °C operation to match typical commercial embedded environments.
• RoHS compliant: Meets environmental regulatory requirements for lead‑free assembly.

Why Choose TD8086?

The TD8086 combines a proven i8086 16‑bit core with simple 5 V I/O and a through‑hole 40‑CDIP package, delivering a practical solution for embedded designers, maintainers of legacy systems, and educational projects. Its support for an external 8087 FPU gives designers the option to add floating‑point capability when needed without changing the base processor.

Manufactured by Intel and offered as a commercial‑grade part, the TD8086 is suited to designs that prioritize straightforward integration, maintainability, and compatibility with established 5 V embedded hardware platforms.
