8 / 15 page Arizona Microtek, Inc. AZPB70 Programmer Board for AZT70/71 www.azmicrotek.com +1-480-962-5881 8 Request a Sample May 2012, Rev 1.2 PROGRAMMING THE AZT70/71 Programming the AZT70/71 is a simple procedure using the included software and programmer board. The following sections describe the internal functions of the software and programmer board in detail. CONTROL WORD The capacitance in the AZT70/71 is controlled by an 11-bit shift register with the data input bit definitions shown in Table 3 and Table 4. The control word data is inputted serially on the rising edge of the CLK signal with bit0 first and bit10 last. Table 3 - AZT70 Control Word Definition 11-bit Control Word bit10 bit9 bit8 bit7 bit6 bit5 bit4 bit3 bit2 bit1 bit0 Not Used Not Used Cmid Clo Not Used MSB --- LSB MSB --- --- --- LSB Table 4 - AZT71 Control Word Definition 11-bit Control Word bit10 bit9 bit8 bit7 bit6 bit5 bit4 bit3 bit2 bit1 bit0 Chi Cmid Clo Not Used MSB LSB MSB --- LSB MSB --- --- --- LSB The control word mapping is binary weighted for each of Chi, Cmid and Clo where higher number bits are more significant. Figure 10 shows the capacitance value mapping for the AZT70. The detailed Nominal Capacitance Binary Mapping for both the AZT70 and AZT71 can be located on the AZM website. |
