10 / 10 page TX25 PIN Type Function i.MX25 Pad Name Alternate functions GPIO Description (refer to I.MX25 manuals for details) 168 3V3 D[7] D[7] 169 3V3 A [0] A [0] 170 3V3 A [1] A [1] 171 GND GND 172 NVDD_DR YICE TAMPER_A TAMPER_A 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. 173 NVDD_DR YICE TAMPER_B TAMPER_B 174 NVDD_DR YICE MESH_C MESH_C 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. 175 NVDD_DR YICE MESH_D MESH_D 176 3V3 A [2] A [2] 177 3V3 A [3] A [3] 178 3V3 A [4] A [4] 179 3V3 A [5] A [5] 180 3V3 A [6] A [6] 181 3V3 A [7] A [7] 182 3V3 A [8] A [8] 183 GND GND 184 analog REF REF 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. 185 analog XN XN Touscreen ADC input channels 186 analog XP XP 187 analog YN YN 188 analog YP YP 189 analog WIPER WIPER 190 analog INAUX0 INAUX0 General purpose measurements channels 191 analog INAUX1 INAUX1 192 analog INAUX2 INAUX2 193 power NVCC_DRYICE NVCC_DRYICE DRYICE power supply output. Source can be SoC supply or backup supply. This pin can be used to power external tamper detect components. 194 3V3 A [9] A [9] 195 3V3 A [11] A [11] 196 3V3 A [12] A [12] 197 NC not connected 198 NC not connected 199 NC not connected 200 GND GND GND Ka-Ro electronics GmbH - Pascalstr. 22, D-52076 Aachen, Germany - Tel.: +49 2408 1402-0 (FAX -10) www.karo-electronics.de |
