FEATURES AND PERFORMANCE
Compared to the 80C186/188 microcontrollers, the Am186™ES and Am188™ES
microcontrollers enable designers to reduce the cost, size, and power consumption of
embedded systems, while increasing performance and functionality. The Am186ES and
Am188ES microcontrollers are cost-effective, enhanced versions of the AMD 80C186/188.
The Am186ES and Am188ES microcontrollers are the ideal upgrade for 80C186/188
designs requiring 80C186/188-compatibility, increased performance, serial
communications, and a glueless bus interface. Developed exclusively for the embedded
marketplace, the Am186ES and Am188ES microcontrollers increase the performance of
existing 80C186/188 systems while decreasing their cost.
Because the Am186ES and Am188ES microcontrollers integrate on-chip peripherals and
offer up to twice the performance of an 80C186/188, they are ideal upgrade solutions for
customers requiring more integration and performance than their present x86 solution
delivers.
KEY FEATURES AND BENEFITS
The Am186ES and Am188ES microcontrollers extend the AMD family of microcontrollers
based on the industry-standard x86 architecture. The Am186ES and Am188ES
microcontrollers are higher-performance, more integrated versions of the 80C186/188
microprocessors, offering an attractive migration path. In addition, the Am186ES and
Am188ES microcontrollers offer application-specific features that can enhance the system
functionality of the Am186EM and Am188EM microcontrollers. Upgrading to the Am186ES
and Am188ES microcontrollers is an attractive solution for several reasons:
The Am186ES and Am188ES microcontrollers are part of the AMD E86 family of embedded
microcontrollers and microprocessors based on the x86 architecture. The E86 family
includes the 80C186, 80C188, 80L186, 80L188, Am186EMLV, Am188EMLV, Am186EM,
Am188EM, Am186ESLV, Am188ESLV, Am186ER, Am188ER, ÉlanSC300, ÉlanSC310,
ÉlanSC400, Am386
microcontrollers.
Minimized total system cost—New peripherals and on-chip system interface logic on the
Am186ES and Am188ES microcontrollers reduce the cost of existing 80C186/188 designs.
x86 software compatibility—80C186/188-compatible and upward-compatible with the
other members of the AMD E86 family. The x86 architecture is the most widely used
and supported computer architecture in the world.
Enhanced performance—The Am186ES and Am188ES microcontrollers increase the
performance of 80C186/188 systems, and the nonmultiplexed address bus offers faster,
unbuffered access to memory.
Enhanced functionality—The new and enhanced on-chip peripherals of the Am186ES
and Am188ES microcontrollers include two asynchronous serial ports, 32 PIOs, a
watchdog timer, additional interrupt pins, a pulse width demodulation option, DMA directly
to and from the serial ports, 8-bit and 16-bit static bus sizing, a PSRAM controller, a 16-
bit reset configuration register, and enhanced chip-select functionality.
