N80C188XL12 16-Bit Micro controller PLCC-48 INTEL HOT
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
peration modes:– Enhanced mode
DRAM refresh control unit
Power-save mode
Direct interface to 80C187 (IA186XL only)
– Compatible mod
Pin-for-pin replacement for NMOS 80186/80188 non-numeric
applications
Integrated feature set
– Static, modular CPU
– Clock generator
– Two independent DMA channels
– Programmable interrupt controller
– Three programmable 16-bit timers
– Dynamic RAM refresh control unit
– Programmable memory and peripheral chip select logic
– Programmable wait state generator
– Local bus controller
– Power-save mode
– System-level testing support (high impedance test mode)
Completely object-code compatible with existing 8086/8088 software
and has ten
additional instructions over 8086/8088
Crystal supports internal 20–25 MHz operation
Direct addressing capability to 1 MByte memory and 64 Kbyte I/O
Available in 68-Lead:
– Plastic Leaded Chip Carrier (PLCC)
Available in 80-Lead:
– Plastic Quad Flat Pack (PQFP)
– Low Profile Quad Flat Pack (LQFP)
Extended Temperature Range (-40°C to +85°C)
Chapter 4, Functional Description, provides details of the IA186XL
and IA188XL
microcontrollers, including the features listed above.
