Product Summary

The KU80C186EC20 is a 16-bit high-integration embedded processor. The KU80C186EC20 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 the KU80C186EC20 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 can be used for a variety of time measurement and waveform generation tasks. A watchdog timer is provided 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 requests. A DRAM refresh unit and 24 multiplexed I/O ports round out the feature set of the KU80C186EC20.
