109 / 200 page  SPEAr1340 Pin description Doc ID 023063 Rev 4 109/200 Table 19. Connectivity - USB 2.0 PHY signals description Signal name Description Type Ball USB_UHC0_DP USB Host 0 D+ IO H1 USB_UHC0_DM USB Host 0 D- IO H2 USB_UHC1_DP USB Host 1 D+ IO D1 USB_UHC1_DM USB Host 1 D- IO D2 USB_UOC_DP USB OTG D+ IO F1 USB_UOC_DM USB OTG D- IO F2 USB_UOC_ID USB OTG mini-receptacle identifier I F4 USB_UOC_VBUS USB OTG power supply pin: – When SPEAr is configured as USB Device, this is a VBUS detect signal. – When SPEAr is configured as USB Host, this is a power supply pin. A charge pump external to the USB PHY must provide power to this pin (and to pin1 of the Micro-USB connector). The nominal voltage for this pin is 5 V. The voltage range is 0-5.25 V. IO F3 Table 20. Connectivity - UART signals description Signal name Description Type Ball UART0 UART0_RXD UART0 receive serial data input IrDA input (SIRIN) IY25 UART0_TXD UART0 transmitted serial data output IrDA output (SIROUT) OY24 UART0_RTSn UART0 request to send modem status output (active low) O AF17 UART0_CTSn UART0 clear to send modem status input (active low) I AF18 UART0_DCDn UART0 data carrier detect modem status input (active low) I AG18 UART0_DTRn UART0 data terminal ready modem status output (active low) O AE17 UART0_DSRn UART0 data set ready modem status input (active low) I AH17 UART0_RIn UART0 Ring Indicator modem status input (active low) I AG17 UART1 UART1_RXD UART1 receive serial data input IrDA input (SIRIN) IY27 UART1_TXD UART1 transmitted serial data output IrDA output (SIROUT) OY26 |
