Introduction

The 56F827EVM is used to demonstrate the abilities of the 56F827 and to provide a

hardware tool allowing the development of applications that use the 56F827.

The 56F827EVM is an evaluation module board that includes a 56F827 part, 16-bit stereo

codec, external memory and a daughter card expansion interface. The daughter card

expansion connectors are for signal monitoring and user feature expandability.

The 56F827EVM is designed for the following purposes:

•

Allowing new users to become familiar with the features of the 56800 architecture.

The tools and examples provided with the 56F827EVM facilitate evaluation of the

feature set and the benefits of the family.

•

Serving as a platform for real-time software development. The tool suite enables

the user to develop and simulate routines, download the software to on-chip or

on-board RAM, run it, and debug it using a debugger via the JTAG/OnCE

TM port.

The breakpoint features of the OnCE port enable the user to easily specify complex

break conditions and to execute user-developed software at full-speed, until the

break conditions are satisfied. The ability to examine and modify all user

accessible registers, memory and peripherals through the OnCE port greatly

facilitates the task of the developer.

•

Serving as a platform for hardware development. The hardware platform enables

the user to connect external hardware peripherals. The on-board peripherals can be

disabled, providing the user with the ability to reassign any and all of the

controller's peripherals. The OnCE port's unobtrusive design means that all of the

memory on the board and on the controller chip are available to the user.
