General Description

The TK80C186XL and the TK80C188XL are both all based on the same die. Unless otherwise noted, discussions of the TK80C186XL can be applied to both parts.

The TK80C186XL is an enhancement of the original 80C86 microprocessor. It offers new features while remaining object code compatible with the original processors.

The small feature sizes (0.35u) used in the TK80C186XL result in a significant power reduction as compared to the original devices. This is enhanced through use of the Power-Save mode, which adjusts the internal clock speed to achieve the power savings.

The TK80C186XL integrates commonly used system peripherals with the 186 CPU core to save space and reduce overall power consumption. A programmable interrupt controller supports and prioritizes 128 external interrupts in additional to the internal interrupts. The TK80C186XL also contains three programmable timer / counters and two DMA channels.
