UPDI Standalone Programmer for Microchip AVR, ATtiny & ATmega Microcontrollers

The UPDI Standalone Programmer is designed for programming Microchip AVR microcontrollers that use the UPDI programming interface. It supports ATtiny 0-series, 1-series, and 2-series, AVR DA, DB, and DD devices, as well as the ATmega 0-series—all without requiring a computer during programming.

Simply load your HEX file(s), configure the programmer, and it's ready to operate as a completely standalone programmer. To determine whether your MCU is supported, please refer to the device compatibility list below.

The UPDI Standalone Programmer is ideal for mass production, programming replacement devices, or updating firmware for customers. If you regularly program multiple devices with the same firmware, this programmer makes the process fast and simple.

The programmer can Program and Verify:

• Flash Memory
• EEPROM
• Fuse Bits
• User Row
• Lock Bits Each operation can be individually enabled or disabled during configuration. Programming bootloaders into new devices is especially convenient. Simply load the bootloader HEX file, configure the required fuse settings, and store them in the programmer's memory. Once configured, you can repeatedly program new devices in just a few seconds without reconnecting to a computer.

Programming is performed through the single-wire UPDI interface using only three connections: VCC, GND, UPDI. A programming cable is included.

There is a growing need for an affordable standalone programmer that supports the UPDI protocol. Unlike traditional programming software, there is no need to install a large, slow, and complicated application just to program a microcontroller.

The UPDI Standalone Programmer is fast, reliable, and easy to use. A computer is only required for the initial setup or whenever you want to change the stored HEX files or configuration settings. The programmer is designed to work with TeraTerm, a simple free terminal program.

Once configured, the programmer operates completely in standalone mode. It can:

• Supply 3.3V or 5V to the target device
• Use power from the target device 3.3V to 5V
• Program a self-powered target operating from 1.8V to 5V

All programming data—including Flash, EEPROM, User Row, Fuse Bits, and Lock Bits—is stored in the programmer's internal memory until you choose to replace it. Standalone operation is enabled simply by installing jumper J1. It couldn't be easier. Be sure to watch the demonstration video to see how quickly the programmer can be configured and used.

Security

The programmer can be password protected to prevent unauthorized use.

Technical Support

After your order ships, please check your email for the user guide and setup instructions. When you purchase this programmer, you're buying directly from the original designer—not a reseller. If you have any questions, you'll receive honest, knowledgeable, and prompt support from someone who designed and built the product. If you've ever purchased a low-cost electronic product from an overseas reseller, you've probably experienced how difficult it can be to get accurate technical support. In many cases, the seller didn't design the product and can't answer even simple technical questions. If you need assistance, simply send me a message through the marketplace or use the email address provided in the user guide. I usually respond very quickly and will do my best to help you successfully program your device.
