E86TM family 80C186- and 80C188-compatible microcontroller with enhanced bus interface
   - Lower system cost with higher performance
   - 3.3-V 0.3-V operation (Am186EDLV microcontrollers)

Programmable DRAM Controller
   - Supports zero-wait-state operation with 50-ns DRAM at 40 MHz, 60-ns at 33 MHz, 70-ns at
     25MHz
   - Includes programmable CAS-before-RAS refresh capability

High performance
   - 20-, 25-, 33-, and 40-MHz operating frequencies
   - Zero-wait-state operation at 40 MHz with 70-ns static memory
   - 1-Mbyte memory address space
   - 64-Kbyte I/O space

Enhanced features provide improved memory access and remove the requirement for a 2x clock input
   - Nonmultiplexed address bus
   - Processor operates at the clock input frequency
   - 8-bit or 16-bit programmable bus sizing including 8-bit boot option

Enhanced integrated peripherals
   - 32 programmable I/O (PIO) pins
   - Two full-featured asynchronous serial ports allow full-duplex, 7-bit, 8-bit, or 9-bit data transfers
   - Serial port hardware handshaking with CTS, RTS, ENRX, and RTR selectable for each port
   - Improved serial port operation enhances 9-bit DMA support
   - Independent serial port baud rate generators
   - DMA to and from the serial ports
   - Watchdog timer can generate NMI or reset
   - A pulse-width demodulation option
   - A data strobe, true asynchronous bus interface option included for DEN
   - Reset configuration register

Familiar 80C186, 80C188 peripherals
   - Two independent DMA channels
   - Programmable interrupt controller with up to 8 external and 8 internal interrupts
   - Three programmable 16-bit timers
   - Programmable memory and peripheral chip-select logic
   - Programmable wait state generator
   - Power-save clock divider
