Data Sheet Guides

To make specialized information easier to find, the FS453/4 and FS455/6 Data Sheet is

organized into separate reference guides. Each guide addresses a different purpose or

user.

 The FS453/4 and FS455/6 Product Brief provides general information for all

users.

; The FS453/4 and FS455/6 Hardware Reference is for

system designers. It provides information on developing

FS453/4 and FS455/6 applications. (This section now includes

PCB Layout Guide)

 The FS453/4 and FS455/6 Software/Firmware Reference is for programmers.

It provides information on programming the FS453/4 and FS455/6.

If you need additional reference guides, contact your Focus Enhancements

Throughout this document "FS453" is used as a general term to reference the FS453,

FS454, FS455, and FS456. The FS453 and FS454 are the PQFP versions of the chip,

and the FS455 and FS456 are the BGA versions of the chip. The FS454 and FS456

support Macrovision anti-copy protection, while the FS453 and FS455 do not.
