AM186EDLV Datasheet | AMD

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 n 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 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 Software-patible with the 80C186 and 80C188 microcontrollers with widely available native development tools, applications, and system software A patible evolution of the Am186EM, Am186ES, and Am186ER microcontrollers Available in the following packages: - 100-pin, thin quad flat pack (TQFP) - 100-pin, plastic quad flat pack (PQFP) n GENERAL DESCRIPTION The Am186TMED/EDLV microcontrollers are part of the AMD E86TM family of embedded microcontrollers and microprocessors based on the x86 architecture. The Am186ED/EDLV microcontrollers are the ideal upgrade for 80C186/188 designs requiring 80C186/188 patibility, increased performance, serial munications, a direct bus interface, and more than 64K of memory. The Am186ED/EDLV microcontrollers integrate a plete DRAM controller to take advantage of low DRAM costs. This reduces memory subsystem costs while maintaining SRAM...
