8 / 84 page  M90E32AS [Datasheet] Atmel-46003B-SE-M90E32AS-Datasheet_02122015 8 2 PIN DESCRIPTION Table-1 Pin Description Name Pin No. I/O Type Description Reset 41 I LVTTL Reset: Reset Pin (active low) This pin should connect to ground through a 0.1 μF filter capacitor and a 10k Ω resistor to VDD. In application it can also directly connect to one out- put pin from microcontroller (MCU). AVDD 1 I Power AVDD: Analog Power Supply This pin provides power supply to the analog part. This pin should connect to DVDD and be decoupled with a 0.1 μF capacitor. DVDD 48 I Power DVDD: Digital Power Supply This pin provides power supply to the digital part. It should be decoupled with a 10 μF capacitor and a 0.1μF capacitor. VDD18 42, 43 P Power VDD18: Digital Power Supply (1.8 V) These two pins should be connected together and connected to ground through a 10 μF capacitor. DGND 19, 44, 47 I Power DGND: Digital Ground AGND 2, 12 I Power AGND: Analog Ground I1P I1N 3 4 I Analog I1P: Positive Input for Analog ADC Channel I1N: Negative Input for Analog ADC Channel These pins are differential inputs for analog ADC channel. These 6 analog ADC channels can be flexibly mapped, refer to 3.4 Analog/ digital Channel Mapping. 1 I2P I2N 5 6 I Analog I2P: Positive Input for Analog ADC Channel I2N: Negative Input for Analog ADC Channel These pins are differential inputs for analog ADC channel. These 6 analog ADC channels can be flexibly mapped, refer to 3.4 Analog/ digital Channel Mapping. 1 I3P I3N 7 8 I Analog I3P: Positive Input for Analog ADC Channel I3N: Negative Input for Analog ADC Channel These pins are differential inputs for analog ADC channel. These 6 analog ADC channels can be flexibly mapped, refer to 3.4 Analog/ digital Channel Mapping. 1 Vref 11 O Analog Vref: Output Pin for Reference Voltage This pin should be decoupled with a 4.7 μF capacitor, it is better to add a 0.1 μF ceramic capacitor. V1P V1N 13 14 I Analog V1P: Positive Input for Analog ADC Channel V1N: Negative Input for Analog ADC Channel These pins are differential inputs for analog ADC channel. These 6 analog ADC channels can be flexibly mapped, refer to 3.4 Analog/ digital Channel Mapping. 1 V2P V2N 15 16 I Analog V2P: Positive Input for Analog ADC Channel V2N: Negative Input for Analog ADC Channel These pins are differential inputs for analog ADC channel. These 6 analog ADC channels can be flexibly mapped, refer to 3.4 Analog/ digital Channel Mapping. 1 V3P V3N 17 18 I Analog V3P: Positive Input for Analog ADC Channel V3N: Negative Input for Analog ADC Channel These pins are differential inputs for analog ADC channel. These 6 analog ADC channels can be flexibly mapped, refer to 3.4 Analog/ digital Channel Mapping. 1 |
