The HPR1V2 is an optional accessory to the PRESTO programmer for programming of the devices with supply voltage and logical levels between 1.2V and 3.3V (as for example Xilinx CoolRunner-II). The PRESTO programmer can program devices with signal levels between 3V and 5V ±10%, but sometimes it is necessary to program a device with lower voltage levels. In such case, the HPR1V2 level shifter must be used. HPR1V2 must be used with external supply voltage from application; it cannot be supplied from the programmer.
