The programmer supports a user-defined JTAG frequency:
SLOW JTAG: 0 – 833 kHz
•
FAST JTAG: approx 1.4 MHz
•
The programmer supports the following JTAG modes:
Single JTAG device connected to programmer
•
Multiple JTAG devices connected in a JTAG Chain
•
JTAG ID can be verified for both Atmel AVR,
•
AT91SAM7 and non-Atmel JTAG devices
JTAG chain validation is also supported
•
The programmer supports a user-defined I2C frequency:
SLOW I2C: 0 – 400 kHz
•
Supports ISP programming of both 100 kHz and 400
•
kHz I2C Serial EEPROMs
This is the Communications Speed (BAUD rate) from
•
the programmer to the Target Device when
communicating via a Boot Loader.
The BAUD rate is configurable from 1,200 to 115
•
kBaud.
This settings is completely independent from the BAUD
•
rate settings for the PC communicating with the
programmer.
The programmer can support any ISP header by simply
plugging in the relevant 'ISPnano Pin-out Converter Module'.
The currently supported ISP Headers are as follows:
Atmel 10-way (SPI)
•
Atmel 6-way (SPI)
•
Atmel 10-way (JTAG)
•
Atmel 20-way (JTAG) for AT91SAM7 microcontrollers
•
Equinox 10-way (SPI+UART)
•
Fast-connect wire connectors
•
Programmer can output a configurable square wave frequency
on the SCK2 pin. This is used to clock the Target Device in the
absence of a Target Oscillator.
Frequency range: 167kHz – 1.8432 MHz
•
The programmer can generate a suitable square wave for use
with 'AVR on-chip oscillator calibration'.
