:?
Friendz,

I'm having M58LW032C Flash IC (TSOP-56).
I want to erase the content of the IC and
reprogram some other data through serial port.
I heard that there are some c based drivers files
available for programming W58LW032C IC.
What is the way to program like this flash IC?
I don't want to use external device like J-TAG for programming.
I want to program directly through serial port.
I'm eagerly looking for the reply.
Thank u very much.

as you can see to write to this chip is , not impossible but difficult at best..
to do a write with the serial port would take intimate knowledge of serial port communications.
also it would require a fairly elaborate circuit , consisting of serial to parrallel shift register, a 3 to 8 line decoder , flip flops to store the signal levels..
hope this helps..

I assume you are going to connect this memory to a microprocessor. In this case the easiest way to program the memory is with a bootloader running on your uP. The bootloader reads from the serial port and then writes the data to the memory.
