Detailed Description

Intel 80C188XL family embedded microprocessor based on the 16-bit x86 80186 architecture

8-bit external data bus for lower system cost while keeping a 16-bit internal core

XL versions are static CMOS and low power. Available in 16 MHz and 12 MHz speed grades

Rich on-chip peripherals designed to cut external glue logic and simplify your board

Key Features

16-bit x86 instruction set compatibility for easy development and legacy support

16 MHz max clock for N80C188XL16 and 12 MHz for N80C188XL12

Integrated peripherals including clock generation, timers, DMA, interrupt controller, chip-select and wait-state logic

8-bit external data bus with multiplexed address data lines and dedicated control signals

Static CMOS core supports idle and power-down modes for power saving

On-chip bus controller simplifies memory and peripheral interface

Wide supply operation depending on variant typically supports 3 V to 5 V range

Commercial and extended temperature options exist by variant and package

Key Advantages

Fewer external components thanks to integrated peripherals

Lower power than older NMOS 80188 devices

Simpler design and reduced PCB area and cost

Mature x86 ecosystem tools and compilers

Easier migration within the 80C186 and 80C188 families when package and pinout match

Packaging

Package case per lot record 1503

Common package styles for 80C188XL include 68-pin PLCC and 80-pin PQFP

Plastic encapsulated IC suitable for reflow or socket mounting depending on package

Pin configuration follows the 80188 XL family with multiplexed address data bus, control signals for memory and I O, and integrated chip-select outputs

Thermal characteristics depend on package and temperature grade. Typical commercial or industrial grades are available

Electrical properties are variant specific. CMOS inputs outputs, typical operation in the 3 V to 5 V range, speed grade aligned to 12 MHz or 16 MHz

Quantity in stock 1400 units

Lifecycle

Intel 80C188XL family is mature and widely considered obsolete or not recommended for new designs

Supply is limited to remaining inventory and secondary sources

Possible functional or second-source alternatives include AMD Am188 family such as Am188ES Am188EM Am188TM, or Intel 80C186XL if an external 16-bit bus and redesign are acceptable

Pinout, voltage, and timing compatibility vary. Always confirm with datasheets before substituting
