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.

Features

• Pin-for-pin compatible with AMD Am186ES/188ES devices

• All features are retained, including:

– A phase-lock loop (PLL) allowing same crystal/system clock frequency

– An 8086/8088 instruction set with additional 186 instruction set extensions

– A programmable interrupt controller

– Two Direct Memory Access (DMA) channels

– Three 16-bit timers

– A wait-state generator and programmable chip select logic

– A dedicated watchdog timer (WDT)

– Two independent asynchronous serial ports (UARTs)

o DMA capability

o Hardware flow control

o 7-, 8-, or 9-bit data capability

– Pulse width demodulator feature

– Up to 32 programmable I/O (PIO) pins

• A pseudo-static/dynamic RAM controller

• A fully static CMOS design

• 40-MHz operation at industrial operating conditions

• +5-VDC power supply
