SP Duo - Advanced AVR Programmer
The SP Duo is an In-System Programmer for Atmel's AVR series of microcontrollers. It can program using the through the SPI or JTAG standards, fast.
Features
- Two programming interfaces: SPI + JTAG
- Fast programming with JTAG
- Fast programming with auto-adapting SPI clock
- STK500 compatible programmer - compatible with existing PC software and IDEs that support the STK500 protocol
- Supports all AVR devices using SPI or JTAG programming
- Supports all In-system-programming functions: programming + readback of Flash, EEPROM, Fuses, Lockbits, and oscillator calibration bytes
- Programmer is firmware-upgradeable to support future AVR devices
- RS-232 interface
- Draws power from target, no external power supply needed
Requirements
-
Target voltage 3.0V-5.5V
- Minimum target clock speed: 250kHz (only for SPI programming)
- Minimum target clock speed for AT90S1200: 1MHz
- 115,200 baud RS-232 COM Port (USB to RS232 adapters are supported)
