AM186EM Datasheet | AMD

features provide faster access to memory and remove the requirement for a 2x clock input - Nonmultiplexed address bus .. - Phase-locked loop (PLL) allows processor to operate at the clock input frequency n New integrated peripherals provide increased functionality while reducing system cost - Thirty-two programmable I/O (PIO) pins - Asynchronous serial port allows full-duplex, 7-bit or 8-bit data transfers - Synchronous serial interface allows half-duplex, bidirectional data transfer to and from ASICs - Pseudo static RAM (PSRAM) controller includes auto refresh capability - Reset configuration register Familiar 80C186/80L186 peripherals - Two independent DMA channels - Programmable interrupt controller with six external interrupts - Three programmable 16-bit timers- timer 1 can be used as a watchdog interrupt timer - Programmable memory and peripheral chip-select logic - Programmable wait state generator - Power-save clock divider Software-patible with the 80C186/80C188 and 80L186 /80L188 microcontrollers Widely available native development tools, applications, and system software Available in the following packages: - 100-pin, thin quad flat pack (TQFP) - 100-pin, plastic quad flat pack (PQFP) n n n n GENERAL DESCRIPTION The Am186TMEM/EMLV and Am188TMEM/EMLV microcontrollers are the ideal upgrade for 80C186/188 and 80L186/188 microcontroller designs requiring 80C186/ 188 and 80L186/188 microcontroller patibility, increased performance, serial munications, and a direct bus interface. The Am186EM/EMLV and Am188EM/EMLV microcontrollers increase the performance of existing 80C186/188 and 80L186/188 systems while decreasing their cost. The Am186EM/EMLV and Am188EM/EMLV microcontrollers are part of the AMD E86 family of embedded microcontrollers and microprocessors based on the x86 architecture. The E86 family includes the 16- and 32-bit microcontrollers and microprocessors described on page 8 The Am186EM/EMLV and Am188EM/EMLV microcontrollers integrate the functions...
