A80188

The A80188 is an Intel i80188-series microprocessor IC featuring a single 16-bit core running at 8 MHz. Designed for embedded applications, it provides a compact, through-hole 68‑PGA package and is offered as a commercial‑grade, RoHS‑compliant component.

Key on‑chip and system capabilities include 5 V I/O signaling, support for an external 80187 floating‑point co‑processor, DRAM controller compatibility and DMA interfaces, making it suitable for embedded designs that require a traditional 16‑bit MPU footprint.

Key Features

• Core and Performance Single 80188 core with a 16‑bit data path running at 8 MHz for deterministic, low‑frequency embedded processing.
• Power and I/O 5 V I/O voltage level suitable for legacy 5 V systems and interfacing with common commercial‑grade peripherals.
• Co‑processor Support External 80187 FPU support for systems that require hardware floating‑point acceleration via a dedicated co‑processor.
• Memory Support DRAM controller compatibility to integrate external dynamic RAM in embedded memory subsystems.
• System Interfaces Integrated DMA support to enable efficient block data transfers without continuous CPU intervention.
• Package and Mounting 68‑PGA supplier device package (29.46×29.46 mm) in a through‑hole mounting format for robust board assembly and mechanical stability.
• Grade and Temperature Range Commercial grade device rated for operation from 0 °C to 70 °C to match standard indoor and controlled‑environment applications.
• Environmental Compliance RoHS compliant for use in products that require lead‑free manufacturing practices.

Typical Applications

• Embedded Control Systems Single‑core 16‑bit processing and DMA support make this MPU suitable for control and sequencing tasks in embedded products.
• Industrial Instrumentation 5 V I/O and through‑hole packaging support integration into instrumentation and measurement platforms with traditional assembly methods.
• Legacy Equipment Maintenance The 8 MHz, 16‑bit architecture and 5 V signaling are appropriate for replacing or maintaining existing legacy systems that require compatible electrical characteristics.
• Educational and Development Platforms Commercial grade operation and straightforward package mounting suit instructional boards and development prototypes that exercise classic 16‑bit MPU designs.
