This datasheet describes the 80C186EB family of microprocessors, which includes the standard voltage versions (80C186EB/80C188EB) and low-voltage variants (80L186EB/80L188EB). These devices are designed for low-power and space-critical applications, offering a static CPU core compatible with object code from the 80C186XL family.
The processors feature an enhanced Bus Interface Unit, a programmable interrupt controller supporting up to 129 external interrupts, three timer/counters, two serial communication channels, and a flexible chip-select unit. They are available in various packages including Quad Flat Pack (QFP), Plastic Leaded Chip Carrier (PLCC), and Shrink Quad Flat Pack (SQFP) with operating frequencies ranging from 3V to 25 MHz.
