MBL8086-2 16bit x86 Microprocessor CPU 5V 8MHz DIP-40
The MBL8086-2 is a high-performance 16-bit central processing unit (CPU) based on the seminal Intel 8086 microprocessor architecture. Designed in NMOS silicon and supplied in a 40-pin dual inline package (DIP-40), this processor integrates a 16-bit data bus and a 20-bit address bus, enabling direct access to up to 1 MB of memory a significant capability for early microcomputer and embedded applications.
Operating typically at 8 MHz, the MBL8086-2 delivers the classic x86 instruction set, powerful segmented memory architecture, and rich register support that became the foundation of modern PC compatibles. This CPU requires external support hardware (memory, clock generator, bus controllers) and is suitable for developing legacy systems, retro computing projects, and educational experimentation with classic microprocessor design.
Features:
- 16-bit CISC CPU implementing the x86/8086 architecture.
- 8 MHz clock speed for MBL8086-2 variant.
- 16-bit data bus and 20-bit address bus (up to 1 MB addressable memory).
- Multiplexed bus for address and data lines (AD0–AD15).
- Compatible with classic x86 instruction set and addressing modes.
- Standard 40-pin DIP package for through-hole prototyping.
- Requires external clock, memory interface (8284), bus controller (8288).
