INTRODUCTION
The M80C186EB is the first product in a new generation of low-power, high-integration microprocessors. It enhances the existing 186 family by offering new features and new operating modes. The M80C186EB is object code compatible with the M80C186/M80C188 microprocessors.

■ Integrated Feature Set
    — Low-Power Static CPU Core
    — Two Independent UARTs each with an Integral Baud Rate Generator
    — Two 8-Bit Multiplexed I/O Ports
    — Programmable Interrupt Controller
    — Three Programmable 16-Bit Timer/Counters
    — Clock Generator
    — Ten Programmable Chip Selects with Integral Wait-State Generator
    — Memory Refresh Control Unit
    — System Level Testing Support (ONCE Mode)
■ Direct Addressing Capability to 1 Mbyte Memory and 64 Kbyte I/O
■ Speed Versions Available:
    — 16 MHz (M80C186EB-16)
