Am186ES Datasheet | Advanced Micro Devices

features provide improved memory access and remove the requirement for a 2x clock input - Nonmultiplexed address bus - Processor operates at the clock input frequency - On the Am186ES/ESLV microcontroller, 8-bit or 16-bit memory and I/O static bus option n Enhanced integrated peripherals provide increased functionality, while reducing system cost - Thirty-two 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 - Multidrop 9-bit serial port protocol - 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 - Pseudo static RAM (PSRAM) controller includes auto refresh capability - Reset configuration register n Familiar 80C186/80L186 peripherals - Two independent DMA channels - Programmable interrupt controller with up to eight external and eight internal interrupts - Three programmable 16-bit timers - Programmable memory and peripheral chip-select logic - Programmable wait state generator - Power-save clock divider n Software-patible with the 80C186/80L186 and 80C188/80L188 microcontrollers with widely available native development tools, applications, and system software n A patible evolution of the Am186™EM and Am188™EM microcontrollers n Available in the following packages: - 100-pin, thin quad flat pack (TQFP) - 100-pin, plastic quad flat pack (PQFP) GENERAL DESCRIPTION The Am186™ES/ESLV and Am188™ES/ESLV microcontrollers are an ideal upgrade for 80C186/188 and 80L186/188 microcontroller designs requiring 80C186/188 and 80L186/188 patibility, increased performance, serial munications, and a direct bus interface. The Am186ES/ESLV and Am188ES/ESLV microcontrollers are part of the AMD E86 family of embedded microcontrollers and...
