IA186EM-PQF100I-R-03

Microcontrollers Overview

The IA186EM-PQF100I-R-03 is a microcontroller IC from Analog Devices Inc., based on the Intel 80C186 architecture. It features an 8/16-bit core with a maximum operating speed of 40MHz. The device is ROMless, requiring external program memory storage. It utilizes a 100-pin PQFP package (20x14mm) for surface mount installation. The unit operates within a voltage range of 4.5V to 5.5V and supports an ambient temperature range of -40°C to 85°C.

Microcontrollers Feature Summary

• Supports external bus interface (EBI) and external memory interface (EMI) for flexible memory expansion
• Integrates internal peripherals including DMA controller, PWM modules, and watchdog timer
• Provides serial communication capabilities via UART/USART interfaces

Microcontrollers Applications

• Industrial control systems requiring robust processing
• Embedded applications needing external memory interfacing
• Automotive electronics operating in extended temperature ranges

Microcontrollers Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS3 compliance and MSL level 3 handling requirements during assembly. Check for specific manufacturing date codes if long-term reliability is critical. Ensure supply chain stability as this part may be discontinued or subject to limited availability.

Microcontrollers Selection Notes

Select this component when an x86-compatible architecture is required for legacy software compatibility. Consider the 100-pin PQFP package constraints for PCB layout. Evaluate the need for external memory given the ROMless nature. Verify that the 40MHz clock speed meets system timing requirements without external oscillators.

Microcontrollers Part Context
