Tekmos Introduces ‘Drop In Replacement’ for Intel 80C186EB and 80C188EB Microprocessors

AUSTIN, Texas, Oct. 5 /PRNewswire/ — Tekmos, Inc. announced today the introduction of its new TK80C186EB and TK80C188EB microprocessors designed as drop-in replacements for the discontinued Intel 80C186EB / 80C188EB microprocessors.

The TK80C186EB 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 interrupts from internal, external, and software sources. The TK80C186EB also contains three programmable timer / counters, two serial channels, 2 parallel ports, and 10 programmable chip selects with programmable wait state generators. The TK80C186EB has a 16-bit external bus, while the TK80C188EB has an 8-bit external bus.

The TK80C186EB is the first in a series of 186 based products. The next processors in the series will be replacements for the 80C186XL / 80C188XL and the 80C186EA / 80C188EA devices, which will be available in Q1 of 2010.

Pricing and Availability

The TK80C186EB and TK80C188EB are available now in the 80 pin SQFP package. Samples in the 84 pin PLCC package will be available in November. Prices start at US $9.65 in 100 piece quantities for the 80-pin SQFP pin version.

Quickly and accurately identify inter-domain leakage issues in IC designs

Sponsored by Siemens Digital Industries Software

Power domain leakage is a major IC reliability issue, often missed by traditional tools. This white paper describes challenges of identifying leakage, types of false results, and presents Siemens EDA’s Insight Analyzer. The tool proactively finds true leakage paths, filters out false positives, and helps circuit designers quickly fix risks—enabling more robust, reliable chip designs. With detailed, context-aware analysis, designers save time and improve silicon quality.
