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.  
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.  
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.  
The Am186ES and Am188ES microcontrollers are part  
of the AMD E86 family embedded microcontrollers and
