ISSI External Flash

Integrated Silicon Solution Inc.

1. XStream-Iso and XStreamPro-Iso adapters can directly program External Flash memory from ISSI, when it is connected via serial peripheral interface to programmer.  

  • Using FlashPro-M and GangPro-M software.
  • ISSI memory must be connected to programming adapter via a serial peripheral interface
  • Up to 1 MBytes/s programming (up to 20MHz, depends on target memory).
  • I/O port configuration can also be saved in configuration file and used in DLL, or shared library.
  • Supports QSPI, SPI programming.

2. The XStreamPro-Iso adapter can program External Flash memory using JTAG/SWD when it is connected to MCU SPI peripheral.  

  • Can program both target MCU internal flash and any connected external flash from ISSI using JTAG/SWD interface only. Does NOT require connection between programmer and external SPI flash memory. The target MCU is used as a proxy for programming. 
  • Using FlashPro-ARM and GangPro-ARM software.
  • ISSI 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.
  • I/O port configuration can also be saved in configuration file and used in DLL, or shared library.
  • Supports JTAG, cJTAG, and SWD communication (this is dependent on target MCU).
  • Supports OCTOSPI, Dual-QSPI, QSPI, SPI programming (multiple ports and modules dependent on target MCU).
