HPR1V2, 1.2V to 3.3V Level Shifter for PRESTO Programmer
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.
