MG80C186-10/B

The Intel MG80C186-10/B is a 16-bit embedded microprocessor from the industry-standard 80C186 family, manufactured to military-grade environmental and reliability specifications for demanding defense and aerospace applications. Operating at 10 MHz and housed in a ceramic pin grid array (CPGA) package, the device integrates essential system peripherals—including a programmable interrupt controller, two-channel DMA controller, three 16-bit timers, and programmable chip-select logic—directly on the die. This integration reduces external component count and improves reliability in size-constrained embedded designs. Its static CMOS core supports low-power operation and flexible clocking, while the CPGA package ensures robust thermal performance and mechanical resilience under severe shock, vibration, and extended temperature conditions common in high-reliability deployments.

Typical end-use scenarios include mission computers, flight control modules, guidance and navigation systems, radar signal processing, and ruggedized industrial controllers where deterministic real-time behavior and long-term availability are critical. The “/B” suffix indicates military or high-reliability processing, often equivalent to a Class B screening flow per MIL-STD-883 or a similar manufacturer-defined qualification, enforcing stringent temperature, burn-in, and visual inspection criteria. As an older Intel embedded processor, the MG80C186-10/B is subject to lifecycle management risk, including potential obsolescence and diminishing supply from authorized channels. Procurement and sustainment planning should emphasize traceable sourcing, counterfeit mitigation, and assessment of compatible supporting devices to maintain continuity in extended program lifecycles and legacy systems requiring form, fit, and function replacement.
