Product data sheet

Table 2: Pin description…continued

Symbol [1] Pin Type Description

REG1V8

70 -

1.8 V regulator output voltage; only for voltage conditioning; cannot

be used to supply power to external components; add a 100 nF

decoupling capacitor

AD[8]

71 I/O bit 8 of multiplexed PCI address and data

PCI pad; 3.3 V signaling

C/BE#[0]

72 I/O byte 0 of multiplexed PCI bus command and byte enable

PCI pad; 3.3 V signaling

GNDA

73 -

analog ground

AD[7]

74 I/O bit 7 of multiplexed PCI address and data

PCI pad; 3.3 V signaling

AD[6]

75 I/O bit 6 of multiplexed PCI address and data

PCI pad; 3.3 V signaling

GNDD

76 -

digital ground

AD[5]

77 I/O bit 5 of multiplexed PCI address and data

PCI pad; 3.3 V signaling

AD[4]

78 I/O bit 4 of multiplexed PCI address and data

PCI pad; 3.3 V signaling

AD[3]

79 I/O bit 3 of multiplexed PCI address and data

PCI pad; 3.3 V signaling

AD[2]

80 I/O bit 2 of multiplexed PCI address and data

PCI pad; 3.3 V signaling

AD[1]

81 I/O bit 1 of multiplexed PCI address and data

PCI pad; 3.3 V signaling

AD[0]

82 I/O bit 0 of multiplexed PCI address and data

PCI pad; 3.3 V signaling

VCC(I/O)

83 -

3.3 V supply voltage; used to power pads; add a 100 nF decoupling

capacitor

GNDA

84 -

analog ground

AUX1V8

85 -

1.8 V auxiliary output voltage; only for voltage conditioning; cannot be

used to supply power to external components; add a 100 nF

decoupling capacitor

XTAL1

86 AI

crystal oscillator input; this can also be a 12 MHz or 48 MHz clock

input

XTAL2

87 AO crystal oscillator output (12 MHz); leave open when clock is used

GNDD

88 -

digital ground

AMB3

89 I/O

amber LED indicator output for the USB downstream port 3; the LED

is off by default and can be programmed to enable it to blink; input as

port indicator enable during reset; by default, pull up is enabled; if no

LEDs are used, then connect this pin to ground, that is, no port

indicator support

3.3 V bidirectional pad; three-state output; 3 ns slew-rate control;

input; CMOS; open-drain

GRN3

90 O

green LED indicator output for the USB downstream port 3; the LED

is off by default and can be programmed to enable it to blink

3.3 V output pad; 3 ns slew rate control; CMOS; open-drain
