APEVIA CORP. USB AVRISP XPII Programmer 12Mbps 1.8-5.5V

SKU CH-AJFM-B34YX

Programs AVR and XMEGA devices via ISP or PDI at up to 8 MHz SCK with 1.8–5.5 V target support

  • Program all AVR and XMEGA devices with ISP or PDI interfaces
  • Adjust ISP clock from 50 Hz to 8 MHz for reliable programming
  • Power targets from 1.8 V to 5.5 V without an external supply
  • USB 2.0 full-speed link at 12 Mbps keeps transfers fast
  • Built-in short-circuit and interface protection safeguards hardware

USB AVRISP XPII Programmer

This USB in-system programmer is built for engineers and hobbyists who develop firmware for AVR microcontrollers. It connects to a host PC over USB 2.0 full speed and draws power from the bus, so no external supply is required. The tool targets any AVR device that exposes an ISP or PDI interface, including XMEGA parts.

1.8 V to 5.5 V target voltage range

The programmer adjusts to the target board voltage across a 1.8 V to 5.5 V window, which is the single specification that decides whether it will drive your design without level shifters. If your hardware sits outside this band the programmer cannot communicate safely.

Handles full AVR flash and EEPROM

It programs flash, EEPROM, fuses and lock bits at adjustable SCK speeds from 50 Hz up to 8 MHz, covering typical development and small-batch production needs. Very large flash arrays or high-volume gang programming will exceed the practical throughput of a single USB 12 Mbps channel.

Questions about this item

How does the 12 Mbps USB link affect programming time on my AVR?

The USB 2.0 full-speed connection moves data at 12 Mbps, so the host-to-programmer path is rarely the bottleneck; actual flash programming speed is set by the adjustable SCK frequency you choose, from 50 Hz up to 8 MHz.

What does the USB 2.0 full-speed interface limit in daily use?

The 12 Mbps USB 2.0 link caps host-to-programmer throughput, but the programmer itself regulates SCK from 50 Hz to 8 MHz, so the practical ceiling is the target MCU's maximum ISP clock, not the USB bus.

What connectors and cables must I have to plug this into a 6-pin ISP header?

The box includes a 6-pin ISP cable and a 6-pin to 10-pin adapter, so you can connect directly to standard 6-pin or 10-pin AVR headers without extra parts.
