LD8088

The LD8088 is an Intel-manufactured iAPX86 family microprocessor implementing a single 8088 core with an 8-bit external data bus and 5 MHz operating speed. Designed for embedded applications, it provides a compact, through-hole 40-CDIP package and supports external 8087 floating-point coprocessors and EBI/EMI system interfaces.

Targeted at commercial-grade embedded designs, the LD8088 operates from a 5 V I/O supply and is specified for a 0 °C to 70 °C operating range, with RoHS compliance for environmental regulation alignment.

Key Features

• Core and Architecture Single 8088 core implementing the iAPX86 architecture with an 8-bit external data bus for legacy and embedded system designs.
• Performance 5 MHz clock speed suitable for deterministic, low-frequency embedded control tasks.
• Power 5 V I/O voltage level to match common TTL/CMOS logic interfaces in commercial systems.
• Co-processor Support External 8087 FPU support for designs that require optional floating-point acceleration.
• Interfaces Additional EBI/EMI interfaces for external bus and memory interfacing in embedded platforms.
• Package & Mounting 40-pin ceramic DIP (40-CDIP) package, through-hole mounting for straightforward board assembly and prototyping.
• Operating Range & Compliance Commercial-grade operation from 0 °C to 70 °C and RoHS compliance for environmental standards.

Typical Applications

• Commercial Embedded Controls Use the LD8088 for low-speed control tasks and system management within commercial embedded equipment.
• Legacy System Maintenance Suitable for repair or refurbishment of existing iAPX86-based hardware that requires a 5 MHz 8088 implementation.
• Hardware Prototyping and Education Through-hole 40-CDIP packaging and a single-core 8088 architecture make the LD8088 appropriate for hands-on development and instructional use.

Unique Advantages

• Direct 5 V I/O Compatibility: Matches common 5 V logic levels to simplify interface design with existing TTL/CMOS peripherals.
• Through-Hole 40-CDIP Packaging: Facilitates board-level assembly and prototyping using standard through-hole processes.
• External 8087 FPU Support: Allows system designers to add dedicated floating-point acceleration when required without changing the main CPU.
• EBI/EMI Interfaces: Built-in external bus/memory interface capabilities to streamline integration with external memory and peripheral devices.
• Commercial Temperature Rating: Specified for 0 °C to 70 °C operation to meet common commercial application environments.
• RoHS Compliant: Conforms to RoHS requirements for environmentally conscious product designs.
