Pin Description
PIN
NAME
FUNCTION
1
AIN7
Analog Input Channel 7. AIN7 is multiplexed to the PGA or ADC as single-ended analog input 7 or as a
differential input with AIN6. As a differential input, the polarity of AIN7 is negative.
2
AIN6
Analog Input Channel 6. AIN6 is multiplexed to the PGA or ADC as a single-ended analog input 6 or as a
differential input with AIN7. As a differential input, the polarity of AIN6 is positive.
3
AIN5
Analog Input Channel 5. AIN5 is multiplexed to the PGA or ADC as single-ended analog input 5 or as a
differential input with AIN4. As a differential input, the polarity of AIN5 is negative.
4
AIN4
Analog Input Channel 4. AIN4 is multiplexed to the PGA or ADC as single-ended analog input 4 or as a
differential input with AIN5. As a differential input, the polarity of AIN4 is positive.
5
REFADC
ADC External Reference Input. Connect an external reference between 1V and VAVDD.
6
AGND
Analog Ground
7
AIN3
Analog Input Channel 3. AIN3 is multiplexed to the PGA or ADC as single-ended analog input 3 or as a
differential input with AIN2. As a differential input, the polarity of AIN3 is negative.
8
AIN2
Analog Input Channel 2. AIN2 is multiplexed to the PGA or ADC as single-ended analog input 2 or as a
differential input with AIN3. As a differential input, the polarity of AIN2 is positive.
9
AIN1
Analog Input Channel 1. AIN1 is multiplexed to the PGA or ADC as single-ended analog input 1 or as a
differential input with AIN0. As a differential input, the polarity of AIN1 is negative.
10
AIN0
Analog Input Channel 0. AIN0 is multiplexed to the PGA or ADC as single-ended analog input 0 or as a
differential input with AIN1. As a differential input, the polarity of AIN0 is positive.
11
I.C.
Internally Connected. Connect to GNDIO for proper operation.
12
P0.0
Port 0 Bit 0. P0.0 is a general-purpose digital I/O with interrupt/wake-up capability.
13
P0.1
Port 0 Bit 1. P0.1 is a general-purpose digital I/O with interrupt/wake-up capability.
14
P0.2
Port 0 Bit 2. P0.2 is a general-purpose digital I/O with interrupt/wake-up capability.
15, 22, 38
GNDIO
Digital I/O Ground and Regulator Ground
16
CANRXD
CAN Bus Receiver Input. CAN receiver input.
17
CANTXD
CAN Bus Transmitter Output. CAN transmitter output.
18
SS
Active-Low, SPI Port Slave Select Input. In SPI slave mode, this is the slave select input. In SPI master
mode, this is an input and connection is optional (connect if mode fault enable is required, refer to the
MAXQ7670 User’s Guide for a description of the SPICN register). In master mode, use an available GPIO
as a slave selector and pull SS high to DVDDIO through a pullup resistor.
19
P0.6/T0
Port 0 Bit 6/Timer 0 I/O. P0.6 is a general-purpose digital I/O with interrupt/wake-up input capability. T0 is a
primary timer/PWM input or output. The alternative function, T0, is selected using the T2CNA0 register.
When this function is selected, it overrides the GPIO functionality.
20
P0.7/T0B
Port 0 Bit 7/Timer 0 Output. P0.7 is a general-purpose digital I/O with interrupt/wake-up input capability.
T0B is a secondary timer/PWM output. The alternative function, T0B, is selected using the T2CNB0 register.
When this function is selected, it overrides the GPIO functionality.
21, 39
DVDDIO
Digital I/O Supply Voltage and Regulator Supply Input. DVDDIO supplies all digital I/O except for XIN and
XOUT, and supplies power to the two internal linear regulators, AVDD and DVDD. Bypass DVDDIO to
GNDIO with a 0.1F capacitor as close as possible to the device.
