SLG46110

7.0 I/O Pins

The SLG46110 has a total of 8 multi-function I/O pins which can function as either a user defined Input or Output, as well as

serving as a special function (such as outputting the voltage reference), or serving as a signal for programming of the on-chip

Non Volatile Memory (NVM).

Normal Mode pin definitions are as follows:

• Pin 1: VDD Power Supply

• Pin 2: General Purpose Input

• Pin 3: General Purpose I/O or Analog Comparator 0 (+)

• Pin 4: General Purpose I/O or Analog Comparator 0 (-)

• Pin 5: No Connect

• Pin 6: General Purpose I/O or Analog Comparator 1 (+) with OE

• Pin 7: Ground

• Pin 8: General Purpose I/O

• Pin 9: General Purpose I/O

• Pin 10: General Purpose I/O with OE and Vref Output

• Pin 11: No Connect

• Pin 12: General Purpose I/O or External Clock Input

Programming Mode pin definitions are as follows:

• Pin 1: VDD Power Supply

• Pin 2: VPP Programming Voltage

• Pin 3: Programming ID Pin

• Pin 7: Ground

• Pin 8: Programming Mode Control

• Pin 9: Programming SDIO Pin

• Pin 10: Programming SRDWB Pin

• Pin 12: Programming SCL Pin

Of the 8 user defined I/O pins on the SLG46110, all but one of the pins (Pin 2) can serve as both digital input and digital output.

Pin 2 can only serve as a digital input pin.

7.1 Input Modes

Each I/O pin can be configured as a digital input pin with/without buffered Schmitt trigger, or can also be configured as a low

voltage digital input. Pins 3, 4, and 6 can also be configured to serve as analog inputs to the on-chip comparators.

7.2 Output Modes

Pins 3, 4, 6, 8, 9, 10, and 12 can all be configured as digital output pins.

7.3 Pull Up/Down Resistors

All I/O pins have the option for user selectable resistors connected to the input structure. The selectable values on these resistors

are 10 k

, 100 k and 1 M. In the case of Pin 2, the resistors are fixed to a pull-down configuration. In the case of all other I/O

pins, the internal resistors can be configured as either pull-up or pull-downs.
