[MULTIX UPDI4AVR Programmer] HV compatible program writer for modernAVR generation
Switch Language (en-US) (ja-JP)
Overview
- New generation AVR 8 bit MCU dedicated program writing device with UPDI programmer.
- Rewriting/backup/verification of Flash/EEPROM/FUSE, etc.
- For tinyAVR-0/1/2, megeAVR-0, AVR DA/DB/DD/DU/EA/EB series only
- HV (high voltage) control for tinyAVR-0/1/2, AVR_DD/DU/EA/EB series
- Providing reset button function to target AVR devices
- LOCK_BIT Lock/unlock
- USERROW special write to locked AVR device
- UART pass-through (assuming use of Arduino IDE serial monitor)
- avrdude compatible (Windows / macOS / Linux / etc)
- Arduino IDE compatible, JTAG2UPDI compatible
- Open source software and hardware
Special features
- Supports two types of high voltage programming: 12V and 8.2V
- Especially the writing device that can handle 8.2V system is unique.
- Blind write to USERROW area of locked AVR device
- Because the control procedure is special, no other implementation examples can be found.
Precautions when purchasing
- Not compatible with older generation AVR (non-UPDI) and SAM generation AVR (JTAG).
- Trace & break debugging is not possible. (Proprietary from Microchip)
- Expensive choice if HV control is not required.
- Because it is handmade, there may be individual differences in appearance.
