3.3 V Level Shifter for PRESTO

HPR3V3 is an optional accessory to the PRESTO programmer for programming of stand-alone 3.3 V devices (as for example DataFlash Memories). The PRESTO programmer can supply a programmed device with 5 V. However, some devices require 3.3 V supply voltage and 3.3 V logic levels on their pins. In such case, the HPR3V3 level shifter or an external 3.3 V power supply have to be used.
