GENERAL: ATMEL FLASH PROGRAM UTILITY FLIP

Information in this article applies to:

• C51 All Versions
• µVision2 Version 2.20a and later
• MCBx51 Evaluation Board

QUESTION

I have used the Keil C51 compiler to compile, build, simulate, and debug my application for the ATMEL T89C51RD2. I want to program the on-chip FLASH on the T89C51RD2. What utility do I use to program the FLASH and set the security bits of the T89C51RD2?

ANSWER

ATMEL provides a Windows-based FLASH programing utility called FLIP. This is a serial-based ISP programing utility that uses the ATMEL boot loader of the T89C51RD2. It allows the user to load and program HEX files into the T89C51RD2 program Flash. FLIP also allows you to set the security bits so that the program code can be secured.

A modification to the Keil MCBx51 evaluation board allows programming the T89C51RD2 with FLIP.

FLIP is available for free download from the ATMEL W&M section of the ATMEL web site http://www.atmel.com.
