GPIO3[18]

“Pulse” indication on finish of internal system reset, by visibility of

“hreset_b“ signal. After reset, this pin can be used for other purposes.

Power On Reset - active low input signal. Typically a push button reset. Pull low to force a reset. Leave unconnected or connect to

3V3 if unused. 63.5kΩ pull-up resistor.

Master Reset - external active low Schmitt trigger input signal.

Alternate functions GPIO Description (refer to I.MX25 manuals for details)

DRYICE external tamper detect pins, active high. If either

TAMPER_A or TAMPER_B asserted, then external tampering is detected. Should be tied to pull-down if no tamper detection is required on board.

Wire-mesh tamper detect pins which can be routed at the PCB board to detect attempted tampering of a protected wire. MESH_C is active high and should be connected to an on-board pull-down if no tamper detection is required. MESH_D is active low and should be connected to an on-board pull-up if no tamper detection is required.

Touchscreen ADC External reference voltage (2.5 V). REF may be left floating if the internally generated 2.5 V supply is enabled. Use of an external reference is recommended.

Touscreen ADC input channels

General purpose measurements channels

DRYICE power supply output. Source can be SoC supply or backup supply. This pin can be used to power external tamper detect components.
