Main features

  • High-speed In-System Programming (ISP) support of Atmel XMEGA AVR microcontrollers via the 4-wire JTAG Interface
  • Supports programming the on-chip FLASH, EEPROM, Fuse and Lock Bits of XMEGA AVR microcontrollers
  • Uses the industry standard JTAG Interface to program the target device
  • Very high-speed programming due to local data storage and optimised programming algorithms
  • Programmers can be used in "Standalone Mode" (no PC) - Up to 64 x XMEGA 'Programming Projects' can be stored inside an ISPnano programmer
  • Supports high-speed program / verify of the XMEGA on-chip FLASH and EEPROM in a singe operation.
  • Optimised Erase operation supports independent erasing of Application Section, Application Table and Boot Section
  • Supports programming of non volatle Fuse Bits
  • Supports programming of the "Security Fuses" (Lock Bits) to protect code from being read out
