E86TM family 80C186- and 80C188-compatible microcontrollers with enhanced bus interface
   - Lower system cost with high performance
   - 3.3-V 0.3-V operation with 5-V tolerant I/O

Memory integration
   - 32 Kbyte of internal SRAM
   - Internal SRAM provides same performance as zero-wait-state external memory

High performance
   - 25-, 33-, 40- and 50-MHz operating frequencies
   - Supports zero-wait-state operation at 50 MHz with 55-ns external memory
   - 1-Mbyte memory address space
   - 64-Kbyte I/O space

Enhanced features provide faster access to memory and various clock input modes
   - Nonmultiplexed address bus provides glueless interface to external RAM and ROM
   - Phase-locked loop (PLL) enables processor to operate at up to four times clock input frequency

Enhanced integrated peripherals
   - Thirty-two programmable I/O (PIO) pins
   - Asynchronous serial port allows full-duplex, 7-bit or 8-bit data transfers
   - DMA to and from asynchronous serial port
   - Synchronous serial interface allows half-duplex, bidirectional data transfer to and from ASICs
   - Reset configuration register
   - Additional external interrupts
   - Hardware watchdog timer can generate NMI or system reset
   - Pseudo static RAM (PSRAM) controller includes auto refresh capability

Familiar 80C186 / 80C188 peripherals with enhanced functionality
   - Two independent DMA channels
   - Programmable interrupt controller with six external interrupts
   - Three programmable 16-bit timers
   - Programmable memory and peripheral chip-select logic
   - Programmable wait state generator
   - Power-save clock mode
