Theory of Operation

The Am186CC/CH/CU microcontroller CDP provides a comprehensive evaluation

system to support Am186CC/CH/CU microcontroller-based designs. The

combined features of the Am186CC/CH/CU microcontroller CDP offer designers

a complete tool for hardware and software development with the Am186CC/CH/

CU microcontrollers.

NOTE: If you are evaluating the Am186CH or Am186CU microcontroller, all of

the features on the CDP are not available. The Am186CH and Am186CU

microcontrollers support subsets of the Am186CC microcontroller features. The

Am186CH HDLC microcontroller provides two HDLC channels and does not

support USB or GCI. The Am186CU USB microcontroller does not support

HDLC.

Features

The Am186CC/CH/CU microcontroller CDP provides the features described in

the following sections.

Main Board

• Am186CC 3.3-V, 50-MHz Microcontroller

• Power Supply (generates 3.3 V, 5.0 V, -5.0 V, -24 V, and -70 V from a 12-V DC

source)

• Memory Interfaces

– Main system memory

4-Mbit, 256K x 16, 40-ns EDO DRAM

Two 1-Mbit 128K x 8, 35-ns SRAMs configured as 128K x 16

– 8-Mbit configurable 512K x 16, or 1M x 8, 55-ns Flash memory
