Note for V4 The latest firmware works at 57600 speed thus giving faster writing speed as compared to earlier firmware V3 that worked on 9600 speeds. You have to upgrade this firmware version 4 as well as software ProLoad to version 4.1 only if you are using the earlier double sided PCB design. Frequently Asked Questions Q: Can I use 89S52 or other kind as firmware IC? A: Yes you can use any 40 pin 8051 type chip as firmware IC. Q: The size of hex file is 11K while 89C52 is just 8kb in size A: Its not logical to compare the size of hex file with the size of memory of IC since HEX size is always greater because it contains address details and other information. This HEX file has memory size of only 3K for data and rest it contains address information.
