AZPB70 Programmer Board for AZT70/71 www.azmicrotek.com +1-480-962-5881 10 Request a Sample May 2012, Rev 1.2 AZT70/71 Programming Board (AZPB70) X1 DA CLK PV DA CLK PV VSS VDD RESONATOR OUT OSCILLATOR Figure 11 – AZT70/71 in Programming Mode AZT70/71 X1 DA CLK PV VSS VDD RESONATOR OUT OSCILLATOR NC NC NC Figure 12 – AZT70/71 in Operational Mode PROGRAMMING MODES The AZT70/71 has two capacitance setting modes from which bits are set and the matching capacitors are selected. Note that all the following described operations can be simply controlled through the included software and programmer board detailed previously. • Reading directly from the shift register o This is useful for testing the capacitance and subsequent oscillator frequency. This mode is active after the last bit is shifted in and when the CLK pin is left logic high. For the shift register, capacitors are selected when bits are active HIGH. • Reading from the value contained in the EEPROM o Prevents customer adjustment and retains factory programming and is active when the CLK pin is at logic low or not connected. For the EEPROM, capacitors are selected when bits are active LOW. |
