IA186ES集成电路（IC）的微控制器规格书PDF中文资料

General Description

The IA186ES/IA188ES family of microcontrollers replaces obsolete AMD Am186ES/188ES devices, allowing customers to retain existing board designs, software compilers/assemblers, and emulation tools and thus avoid expensive redesign efforts.

The IA186ES/IA188ES microcontrollers are an upgrade for the 80C186/188 microcontroller designs, with integrated peripherals to provide increased functionality and reduce system costs. The Innovasic devices are designed to satisfy requirements of embedded products designed for telecommunications, office automation/storage, and industrial controls.
