GENERAL DESCRIPTION
The Net186 evaluation board meets the needs of cus-
tomers working with embedded networking control
applications using the Am186ES microcontroller and
the PCnet-ISA II single-chip Ethernet controller. This
board provides a complete stand-alone, microcontrol-
ler and Ethernet-based evaluation in a low-cost, excep-
tionally small form-factor product.
This evaluation board features the Am186ES, high-per-
formance, 80C186-compatible, 16-bit embedded con-
troller, and the PCnet-ISA II high performance, 16-bit,
single-chip Ethernet controller for ISA.
The microcontroller section consists of the Am186ES,
512 Kbytes FLASH and 512 Kbytes SRAM. The Ether-
net section consists of a PAL for glue logic and the
Am79C961A PCnet-ISA II. The design takes advan-
tages of the Bus Mastering capability of the PCnet-ISA
II to achieve high performance and low system cost,
while reducing the amount of software overhead on the
microcontroller.
Communication with the Net186 can be accomplished
through either one of the two RS-232 serial ports or
through the high speed 10 Mbps Ethernet
10Base-T port.
Am186ES Microcontroller
The Am186ES microcontroller and its companion
Am188ES microcontroller integrate the functions of the
CPU, non-multiplexed address bus, three timers, a
watchdog timer, chip selects, interrupt controller, two
DMA controllers, PSRAM controller, asynchronous
serial ports, programmable bus sizing, and program-
mable I/O (PIO) pins on one chip. Compared to the
80C186/188 microcontrollers, the Am186ES and the
Am188ES microcontrollers can reduce the size, power
consumption, and cost of embedded systems, while in-
creasing reliability, functionality, and performance.
The Am186ES and Am188ES microcontrollers are part
of the AMD E86 family embedded microcontrollers and
