Rochester Electronics TN80C186EA-13

The 80C186EA is a CHMOS high integration embedded microprocessor. The 80C186EA includes all of the features of an “Enhanced Mode" 80C186 while adding the additional capabilities of Idle and Powerdown Modes. In Numerics Mode, the 80C186EA interfaces directly with an 80C187 Numerics Coprocessor. The feature set of the 80C186EA/80L186EA meets the needs of low-power, space-critical applications. Low-power applications benefit from the static design of the CPU core and the integrated peripherals as well as low voltage operation. Minimum current consumption as achieved by providing a Powerdown Mode that halts operation of the device, and freezes the clock circuits. Peripheral design enhancements ensure that noninitialized peripherals consume little current. The 80C186EA is the second product in a new generation of low-power, high-integration microprocessors. It enhances the existing 80C186XL family by offering new features and operating modes. The 80C186EA is object code compatible with the 80C186XL embedded processor. The 80L186EA is the 3V version of the 80C186EA. The 80L186EA is functionally identical to the 80C186EA embedded processor. Current 80C186EA customers can easily upgrade their designs to use the 80L186EA and benefit from the reduced power consumption inherent in 3V operation. Space-critical applications benefit from the integration of commonly used system peripherals. Two flexible DMA channels perform CPU-independent data transfers. A flexible chip select unit simplifies memory and peripher
