121 / 199 page  R8C/10 Group Rev.1.20 Jan 27, 2006 page 111 of 180 REJ09B0019-0120 14.5 Internal Equivalent Circuit of Analog Input 14.5 Internal Equivalent Circuit of Analog Input Figure 14.8 shows the internal equivalent circuit of analog input. Figure 14.8 Internal Equivalent Circuit to Analog Input VCC VCC VSS i =10 VSS SW2 SW1 AN0 ANi VREF Parasitic diode Parasitic diode ON resistor approx. 2k Ω Wiring resistor approx. 0.2k Ω ON resistor approx. 0.6k Ω ON resistor approx. 0.6k Ω ON resistor approx. 5k Ω Analog input voltage VIN SW1 ON resistor approx. 2k Ω Wiring resistor approx. 0.2k Ω AVCC AMP SW3 Chopper-type amplifier A/D successive conversion register A/D conversion interrupt request SW1 conducts only on the ports selected for analog input. SW2 and SW3 are open when A/D conversion is not in progress; their status varies as shown by the waveforms in the diagrams on the left. SW4 conducts only when A/D conversion is not in progress. Warning: Use only as a standard for designing this data. Mass production may cause some changes in device characteristics. SW4 AVSS C = Approx.1.5pF SW2 Vref Comparison voltage Sampling control signal Reference control signal Comparison reference voltage (Vref) generator Sampling Connect to Connect to Comparison Resistor ladder AVSS Control signal for SW2 A/D control register 0 b1 b2 b0 Connect to Connect to Control signal for SW3 i ladder-type switches (i = 10) i ladder-type wiring resistors (i = 10) |
