I am programming memory chips and I am providing power to the target device from a separate power supply. I will not be using USB power because the memory chips use 3.3V. I have a voltage regulator installed before the chip power pins, which seems to interfere with using the Cheetah SPI Host Adapter.

Q: I need to perform in circuit programming (ICP) for Microchip SST25VF080B. Looking at the specifications, it looks like the Cheetah SPI Host Adapter will work for this. Are there other tools can I use with Cheetah adapter for programming an SPI device, which is soldered onto a PCB?
A: Thanks for your question! You can use Cheetah SPI Host Adapter to program SPI memory devices with our software tools: Control Center Software, Flash Center Software and Cheetah Software API.
Flash Center software helps you to quickly erase, program, and verify SPI (and I2C) based EEPROM and flash memory Chips. Flash Center software also provides an XML parts library: built-in support for EEPROMs and serial flash chips from many manufacturers, including the Microchip SST25VF080B. In this case, you don't need to create an API for your in circuit programming.
You can program memory that is already soldered onto a printed circuit board (PCB) through the SPI signals (MOSI, MISO, SS, SCLK), ground signal (GND), and power signal (+5V, if needed). The board should have the ability to connect these signals between the memory device and the Cheetah 10-pin SPI connector. If the board has a matching 10-pin connector, you can interface Cheetah to the chip with the Total Phase 10-pin split cable. Otherwise, you can use the Total Phase 10-pin grabber clip split cable.
For an example of programming an SPI device, see Knowledge Base article: Programming SST SPI Flash Using Cheetah Adapter and Flash Center Software.
