Hi, I have developed a firmware with P80C32SBAA controller with external ROM AT27C512R. Now i want to migrate to AT80C51RD2. I observed Pin to Pin configuration are same in both controllers. I replaced P80C32SBAA with AT80C51RD2, but the firmware is not working. Is there any configuration settings to be changed? firmware was developed in KEIL Uvision4 IDE.
Thank you, Ramesh Chand S
Hi Eric, Thank you for the reply. Can you suggest me the configuration for AT80C51RD2 when we use external ROM
