IA186EM/IA188EM
8/16-BIT Microcontrollers
Data Sheet
As of Production Version -03
Description
The IA186EM/188EM family of microcontrollers replaces obsolete AMD# Am186EM/188EM devices,
allowing customers to retain existing board designs, software compilers/assemblers and emulation tools,
thereby avoiding expensive redesign efforts.
The IA186EM/188EM 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 created to satisfy requirements of embedded products designed for telecommunications, office
automation and storage and industrial controls.
A block diagram of the IA186EM/188EM microcontroller is depicted in Figure 1. The IA186EM/188EM
microcontroller consists of the following functional blocks, with brief discussions of each afterwards.
" Bus Interface and Control
" Peripheral Control and Registers
" Chip Selects and Control
" Programmable I/O
" Clock and Power Management
" Direct Memory Access (DMA)
" Interrupt Controller
" Timers
" Asynchronous Serial Ports
" Synchronous Serial Interface.
