Adesto External Flash

Adesto Technologies

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

  • Using FlashPro-M and GangPro-M software.
  • Adesto Technologies 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. Exclusively, the XStreamPro-Iso adapter comes with External Flash memory programming capability when it is connected to MCU via serial peripheral interface.  

  • Using FlashPro-ARM and GangPro-ARM software.
  • Adesto Technologies memory must be connected to MCU via a working serial peripheral interface (QSPI, SPI, etc.).  The MCU is used as a proxy for programming. 
  • Up to 1 MBytes/s programming (up to 20MHz JTAG/SWD, peripheral interface clock configurable dependent on target MCU).
  • 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 QSPI, SPI programming (multiple ports and modules dependent on target MCU).  OCTOSPI support coming soon.
