The device connects to USB and supports a variety of memory ICs, seems like a handy tool to program bootloader chips, store settings, or dump memory safely. My idea is to use it when I need to program external EEPROMs (or SPI flash) instead of using the microcontroller’s onboard memory, for example, storing configuration data, calibration values, or firmware backups. This way, I don’t risk corrupting the main firmware if something goes wrong. Before I start, I have a few questions I hope some of you veteran members can help with: What’s the typical workflow you use with external EEPROM/flash + programmer? Do you program the chip separately then solder it to your board, or do you use a socket so you can re-flash easily? For projects that run continuously (sensors, data logging), do you trust external flash for frequent writes? What’s your experience with wear leveling or write-cycle limits? Any PCB layout or wiring tips when using external EEPROM/flash, to avoid noise or data corruption, especially if the board also handles analog or sensitive signals? If anyone here has used the EPC1PC8 or a similar USB flash programmer with microcontrollers, I’d love to hear how you integrated it into your build, and what pitfalls to avoid.
