Parallel High-Voltage

Programming

The STK526 is compatible with the Parallel Programming mode of the STK500. The

embedded RESET circuitry supports the HighVoltage pulses used during programming.

Once the STK526 is plugged into the STK500 Expand connectors, the following

configuration must be set before powering the boards :

On the STK526 :

– set the primary power source (Vcc Src jumper) to STK and REG 5V

– set the 3V3REG jumper to “NOREG”

– mount the jumper STKX1 to enable the STK500 clock signal

On the STK500 :

– connect the PROG_CTRL header (10 pts) to the PORTD header (10pts)

– connect the PROG_DATA header (10 pts) to the PORTB header (10pts)

– mount the following jumpers : VTARGET, RESET, XTAL1, BSEL2

– mount a jumper on the position 1-2 (= right side) of the OSCSEL header

All the Flash memory, EEPROM, all Fuse and Lock Bit can be programmed individually

or with the sequential automatic programming option.
