What is ISP Pinout?

ISP means “In-System Programming”.In-System Programming (ISP) allows communication to take place with a target chip without the need to remove it. The main advantage of this method is the possibility to communicate with a target chip eMMC or eMCP bypassing the CPU. It brings higher speed for data extraction compared with JTAG but it requires great soldering skills. ISP applied to forensics, is the practice of connecting to an eMMC or eMCP flash memory chip for the purpose of downloading a device’s complete memory contents.

Why do we need ISP Pinout?

Just Like “Joint Test Action Group (JTAG)” there are specific contacts that will be of interest to the examiner. But unlike JTAG, the contacts are directly off the chip BGAs and do not go through the processor. Acquires data much faster than JTAG, enabling examiners to process more phones faster.
