ISSI External Flash

In-Circuit Programming of Integrated Silicon Solution Inc. Serial Flash over SPI or JTAG/SWD

1. FlashPro-M and GangPro-M (XS, X2S):

  • External serial flash memory must be connected to programming adapter using a serial peripheral interface connection (SPI).
  • Up to 1 MBytes/s programming (up to 20MHz, depends on target memory).

2. FlashPro-ARM and GangPro-ARM (X2S): 

  • Same as above, can program serial flash directly over SPI, and also:
  • Can program both target MCU internal flash and any connected external serial flash using JTAG/SWD interface only.
  • To program using MCU, memory must be connected to target MCU via a working serial peripheral interface (OCTOSPI, Dual-QSPI, QSPI, SPI, etc.). 
  • I/O port configuration utility provided in GUI. Allows interactive configuration of MCU peripheral interface pins to memory.
