SLG46140
7.0 I/O Pins
The SLG46140 has a total of 12 general purpose I/O pins (GPIO) which can be configured as either Input or Output, some with
special functions (such as outputting the Vref), or serving as a signal for programming of the on-chip NVM.
Normal Mode pin definitions are as follows:
• Pin 1: VDD Power Supply
• Pin 2: General Purpose Input (GPI)
• Pin 3: GPIO with Output Enable (OE)
• Pin 4: GPIO with OE, ACMP0(-) Input, PGA Output
• Pin 5: GPIO with OE, ACMP1(-) Input
• Pin 6: GPIO without OE, PGA(+)
• Pin 7: GPIO with OE, PGA(-)
• Pin 8: GND
• Pin 9: GPIO with OE, 4x Drive Output, ACMP1(+) Input
• Pin 10: GPIO, 4x Drive Output, ACMP0(+) Input
• Pin 11: GPIO, ADC Channel Select
• Pin 12: GPIO with OE
• Pin 13: GPIO with OE
• Pin 14: GPIO with OE
Programming Mode pin definitions are as follows:
• Pin 1: VDD Power Supply
• Pin 2: VPP Programming Voltage
• Pin 3: RTSB
• Pin 10: Programming Mode Control
• Pin 11: Programming ID
• Pin 12: Programming SDIO
• Pin 13: Programming SRDWB
• Pin 14: Programming SCL
7.1 Input Modes
Digital Input
Each GPI, GPIO pin can be configured as a:
• Digital input with/without buffered Schmitt Trigger
• Low Voltage Digital Input (LVDI)
Pin 2 can function as a RESET pin
Analog Input
• Pin 3 can function as an analog input for the ADC Vref
• Pins 4, 5, 9, 10 can function as analog inputs for the ACMPs
• Pins 6 and 7 can function as analog input for PGA(+) and PGA(-), respectively
7.2 Output Modes
Pins 3, 4, 5, 9, 12, 13, and 14 can be configured as a digital output with 1x/2x push pull, 1x/2x Open Drain NMOS, or 1x/2x 3-state
output with output enable.
