1. General description

2. Features

The ISP1104 Universal Serial Bus (USB) transceiver is compliant with the

Serial Bus Speciﬁcation Rev. 2.0

full-speed (12 Mbit/s). It allows single and differential input modes selectable by a MODE input.

It allows USB Application Speciﬁc Integrated Circuits (ASICs) and Programmable Logic Devices (PLDs) with power supply voltages from 1.65 V to 3.6 V to interface with the physical layer of the USB. It has an integrated 5 V-to-3.3 V voltage regulator for direct powering via the USB supply line V to detect the presence of the V the D+ and D− pins can be shared with other serial protocols.

[1] Signal levels on pins D+ and D− are determined by other USB devices and external pull-up or

[2] In the suspend mode (pin SUSPND = HIGH), the differential receiver is inactive and the output RCV is

always LOW. Out-of-suspend (K) signalling is detected via the single-ended receivers VP and VM.

7.3 Power supply conﬁgurations

The ISP1104 can be used with different power supply conﬁgurations, which can be changed dynamically. Table 8 provides an overview of power supply conﬁgurations.

ISP1104

Advanced USB transceiver

Normal mode — Both V

is connected to a 5 V source (4.0 V to 5.5 V). The internal voltage regulator

CC(5.0)

then produces 3.3 V for USB connections. V

CC(I/O)

and V

are connected. For 5 V operation,

CC(5.0)

is independently connected to a

CC(I/O)

voltage source (1.65 V to 3.6 V), depending on the supply voltage of the external circuit.

Disable mode — V

is not connected and V

CC(I/O)

is connected. In this mode,

CC(5.0)

the internal circuits of the ISP1104 ensure that the D+ and D− pins are in three-state and the power consumption drops to the low-power (suspended) state level. Some hysteresis is built into the detection of V

Sharing mode — V

is connected and V

CC(I/O)

CC(5.0)

< 3.6 V to differentiate between

. In this mode, pins D+ and

BUS

D− are made three-state and the ISP1104 allows external signals of up to 3.6 V to share the D+ and D− lines. The internal circuits of the ISP1104 ensure that virtually no current (maximum 10 µA) is drawn via the D+ and D− lines. The power consumption through pin V

CC(I/O)

and pin V

drops to the low-power (suspended)

CC(5.0)

state level. Pins VP and VM are drivenHIGH and pins VBUSDET and RCV are driven LOW to indicate this mode. Some hysteresis is built into the detection of V
