7 / 75 page  IA186XL/IA188XL Data Sheet 16-Bit Microcontrollers July 6, 2011 IA211080711-09 http://www.Innovasic.com UNCONTROLLED WHEN PRINTED OR COPIED Customer Support: Page 7 of 75 1-888-824-4184 ® 1. Introduction The Innovasic Semiconductor IA186XL and IA188XL microcontrollers are form, fit, and function replacements for the original Intel 80C186XL and 80C188XL 16-bit high-integration embedded processors. These devices are produced using Innovasic’s Managed IC Lifetime Extension System (MILES™). This cloning technology, which produces replacement ICs beyond simple emulations, ensures compatibility with the original device, including any “undocumented features.” Additionally, the MILES™ process captures the clone design in such a way that production of the clone can continue even as silicon technology advances. The IA186XL and IA188XL microcontrollers replace the obsolete Intel 80C186XL and 80C188XL devices, allowing users to retain existing board designs, software compilers/assemblers, and emulation tools, thereby avoiding expensive redesign efforts. 1.1 General Description The Innovasic Semiconductor IA186XL and IA188XL microcontrollers have a set of base peripherals beneficial to many embedded applications and include a standard numeric interface, an interrupt control unit, a chip-select unit/Ready Generation Logic, a DRAM refresh control unit, a Power-Save Control unit, DMA and three 16-bit timer/counters. The IA186XL and IA188XL microcontrollers operate at 5.0 volts ± 10%. The following functional description describes the base architecture of the 80C186XL. The 80C186XL is a very high integration 16-bit microprocessor. It combines some of the most common microprocessor system components onto one chip. The 80C186XL is object-code compatible with the 8086/8088 microprocessors and adds ten new instruction types to the 8086/8088 instruction set. The 80C186XL has two major modes of operation, Compatible and Enhanced. In Compatible Mode, the 80C186XL is completely compatible with the 80186, with the exception of 8087 support. The Enhanced mode adds three new features to the system design. These are Power- Save control, Dynamic RAM refresh, and an asynchronous Numerics Coprocessor interface (80C186XL only). 1.2 Features The primary features of the IA186XL and IA188XL microcontrollers are as follows: Form, fit, and function compatible version of the low power Intel 80C186XL/80C188XL Operation modes: – Enhanced mode o DRAM refresh control unit |
