About the SD186ER Demonstration Board

1.2

The AMD SD186ER Demonstration Board is designed as an exceptionally small, low-cost product for demons tration of the AMD page ix for a block diagram of the board.

The SD186ER demonstration board is a stand-alone evaluation platform for the Am186ER microcontroller. The Am186ER microcontroller integrates 32 Kbyte of RAM along with peripherals such as 13 chip-select controllers, one asynchronous serial port, one synchronous serial port, 32 programmable I/Os, three timers, an interrupt controller, an d a hardware watchdog timer to increase system functionality while reducing overall cost. The memory controller supports a glueless connection to EPROM, Flash memory, pseudo-static RAM, and SRAM. The Am186ER microcontroller also features an innovative bus design that frees the processor to run at nearly twice the speed of standard 80C186 processors while using commodity memory devices.

The SD186ER demonstr ation board is designed wi th a 104-pin Am186 expansion interface that provides access to the Am186ER microcontroller signals. The Am186 expansion interface facilitates prototyping with external devices by using the SD186ER demonstration board as the minimal system core of a design.

The SD186ER demonstration board highlights the Am186ER microcontroller’s asynchronous serial port, internal RAM, glueless interface to Flash memory, and expansion interface to peripheral attachments. A complete description of the boa rd can be found in Chapter 2, “Demonstration Board Functional Description”.

microcontroller’s performance and functionality. The minima l number of components on the board exhibits the integration present in the processor.

Demonstration Board Features

The SD186ER demonstration board provides the following features:

• Am186ER 50-MHz microcontroller

•E86

family boot monitor (E86MONTM) board-resident utility

Information on invoking and using the E86MON software is provided in the

E86MON

• 256 Kbyte Am29F200-55 Flash memory

• Am186 104-pin expansion interface

• One RS-232 serial port with DB-9 connector

• Activity LED indicators for PIO signals

• Power-on LED indicator

• Reset circuitry
