Am186TMEM/EMLV and Am188TMEM/EMLV are high-performance, 80C186-/80C188-compatible and 80L186-/80L188-compatible, 16-bit embedded microcontrollers with enhanced bus interface, lower system cost and higher performance.
The AMD Am186EM/EMLV and Am188EM/EMLV microcontrollers are part of the AMD E86 family. They offer enhanced bus interfaces, support for zero-wait-state operation at high frequencies (up to 40 MHz), and integrated peripherals such as asynchronous and synchronous serial ports, DMA channels, and programmable timers.
These devices are designed to reduce system cost and size while increasing functionality compared to previous 80C186/80L188 designs. They feature a nonmultiplexed address bus, a phase-locked loop (PLL), and operate in voltage ranges from 3.3V to 5V depending on the specific model.
