FlashcatUSB Professional
Introducing the new hardware version (PCB 3.x) with over ten times the performance. This upgraded version includes an all new chipset, integrated power supply controller, easier to use polarized connectors, and large internal memory that can run a single firmware with all of the previous FlashcatUSB protocols and features. NEW: now includes case.


SPI socket adapters (SO8, SO16, DIP8, WSON8) are available here

Parallel sockets (PLCC-32, TSOP-48, TSOP-56) are available here

Hardware Features:

  • High-performance 120MHz ARM 32-bit processor

  • 128KB internal memory and 64KB RAM

  • Automatic firmware updating over USB

  • High-speed (SPI up to 70 MHz, JTAG up to 30 MHz)

  • Output voltage selectable via software (1.8v / 3.3v / 5v)

  • Dual voltage regulators with up to 300ma output

  • Dual IDC headers for SPI, I2C and JTAG connections

  • Compatible with all PCB 2.x sockets and adapters

  • Combine up to 5 to make a production multi-chip programmer (see screenshot)

  • Designed for production environments (not for in-circuit use)
