# Dumping TSOP48 flash

I'm trying to understand how to dump a flash device myself without using a universal programmer.

I have this chip S29GL032N90TFI040, I also have TSOP48 socket The datasheet specifies the table of the device bus operations (page 17):

In SPI flashes that I dumped before the datasheets of the SPI flashes had its specific and easy to understand command for reading data, for example [0xB] [A1] [A2] [A3] [Dummy byte] [Dummy byte] [Dummy byte], after this command the SPI flash would spit out its contents from address [A1][A2][A3] until CS# was LOW, After looking in the datasheet of S29GL032N90TFI040, I didn't see the commands that are needed to be sent in order to retrieve data from this flash, only the table of device bus operations, which specifies the device bus operations pins but not the command that is needed to be sent or the ordering (there is a read operations timing image in page 65, but it is still not enough information for writing a programmer for this specific chip.)

My questions are:

1. How can I find out the specific command that is needed to be sent, the order of the command, the number of bytes that will be retrieved from the input address?

2. What Arduino like board is recommended and have enough pins to program TSOP48 chips?

Note: I know there are Universal Programmers that will make my life easy, But I don't like easy.

Thanks.
