Xilinx yana gabatar da jerin XC18V00 na cikin-tsarin daidaitawar PROMs (Hoto 1).Na'urorin da ke cikin wannan dangin 3.3V sun haɗa da 4-megabit, 2-megabit, 1-megabit, da kuma 512-kilobit PROM waɗanda ke ba da sauƙi mai sauƙi, hanya mai tsada don sake tsarawa da adanawa lokacinx FPGA sanyi bitstreams.

Lokacin da FPGA ke cikin Yanayin Serial Master, yana haifar da agogo mai daidaitawa wanda ke tafiyar da PROM.Wani ɗan gajeren lokacin shiga bayan an kunna CE da OE, ana samun bayanai akan fil ɗin PROM DATA (D0) wanda ke haɗa da fil ɗin FPGA DIN.Sabbin bayanai suna samun ɗan gajeren lokacin samun dama bayan kowace gefen agogo mai tashi.FPGA yana haifar da adadin adadin agogon da ya dace don kammala daidaitawa.Lokacin da FPGA ke cikin yanayin Serial Slave, PROM da FPGA ana rufe su da agogon waje.

Lokacin da FPGA ke cikin Jagora Zaɓi Yanayin MAP, FPGA yana haifar da agogo mai daidaitawa wanda ke tafiyar da PROM.Lokacin da FPGA ke cikin Slave Parallel ko Slave Select MAP yanayin, wani oscillator na waje yana haifar da agogon sanyi wanda ke tafiyar da PROM da FPGA.Bayan an kunna CE da OE, ana samun bayanai akan fil ɗin DATA (D0-D7).Sabbin bayanai suna samun ɗan gajeren lokacin samun dama bayan kowace gefen agogo mai tashi.An rufe bayanan a cikin FPGA a gefen hawan CCLK mai zuwa.Ana iya amfani da oscillator mai gudana kyauta a cikin Ma'anar Bawa ko Slave Select MAP.
