Product Summary

The QU80C188EC-25 is one of the highest integration members of the 186 Integrated Processor Family. Two serial ports are provided for services such as interprocessor communication, diagnostics and modem interfacing. Four DMA channels of QU80C188EC-25 allow for high speed data movement as well as support of the onboard serial ports. A flexible chip select unit simplifies memory and peripheral interfacing. The three general purpose timer/counters of QU80C188EC-25 can be used for a variety of time measurement and waveform generation tasks. A watchdog timer is provided by QU80C188EC-25 to insure system integrity even in the most hostile of environments. Two 8259A compatible interrupt controllers handle internal interrupts, and, up to 57 external interrupt I/O ports round out the feature set of the QU80C188EC-25.
