29 / 53 page 4116369 Rev 9.0 September 04, 2017 29 Product Technical Specification Detailed Interface Specifications 3.7. Electrical Information for Digital I/O The AirPrime HL7548 and HL7588 support two groups of digital interfaces with varying current drain limits. The following list enumerates these interface groupings and the following table enumerates the electrical characteristics of each digital interface. • Group 1 (6mA current drain limit) ▪ GPIO2, GPIO3, GPIO4, GPIO6, GPIO8, GPIO10, GPIO11, GPIO13, GPIO14, GPIO15 • Group 2 (1mA current drain limit) ▪ GPIO1, GPIO5, GPIO7 ▪ UART1 ▪ JTAG ▪ PCM Table 15. Digital I/O Electrical Characteristics Parameter Symbol Minimum Maximum Remarks Input Current-High(µA) IIH - -240 Input Current-Low(µA) IIL - 240 Group 1 DC Output Current-High (mA) IOH - 6 DC Output Current-Low (mA) IOL -6 - Group 2 DC Output Current-High (mA) IOH - 1 DC Output Current-Low (mA) IOL -1 - Input Voltage-High(V) VIH 1.33 1.90 Input Voltage-Low(V) VIL -0.20 0.34 Output Voltage-High(V) VOH 1.45 - IOH = -6mA VOH 1.60 - IOH = -0.1mA Output Voltage-Low(V) VOL - 0.35 IOL = 6mA VOL - 0.20 IOL = 0.1mA 3.8. General Purpose Input/Output (GPIO) The AirPrime HL7548 and HL7588 modules provide 13 GPIOs, 3 of which have multiplexes. Table 16.
