TD8088

The TD8088 is an Intel i8086-series microprocessor implementing a single 8088 core with an 8-bit external data bus and 5 MHz clock speed. It is supplied in a 40-pin ceramic DIP package and is targeted at embedded, through-hole applications requiring a commercial-grade processor.

Designed for systems that require a straightforward, single-core 8088 architecture, the TD8088 offers compatibility with external 8087 floating-point co-processors and includes EBI/EMI interfaces for system integration. The device is RoHS compliant and rated for commercial operating temperatures.

Key Features

• Core Processor  8088 core providing a single 1-core architecture with an 8-bit external bus.
• Clock Speed  5 MHz operating frequency suitable for legacy and low-to-moderate performance embedded tasks.
• Power  5 V I/O voltage compatible with common embedded system supply rails.
• Co‑processor Support  External 8087 FPU support enables hardware floating-point acceleration when paired with the appropriate co-processor.
• Interfaces  Built-in EBI/EMI interfaces to facilitate external memory and peripheral connections.
• Package & Mounting  40-pin CDIP package (40-CDIP) in through-hole form factor for soldered or socketed board mounting.
• Operating Range & Grade  Commercial grade device specified for 0 °C to 70 °C operation.
• Environmental Compliance  RoHS compliant for regulatory and manufacturing alignment.

Typical Applications

• Embedded Systems  Suitable for embedded designs requiring a single-core 8088 processor with an 8-bit bus and 5 MHz operation.
• Legacy Equipment Maintenance  Fit for repair or continued production of systems designed around the 8088 architecture and 40-pin through-hole packages.
