range,

-40 °C to +85 °C.

2 Description

Agere's USS810 is a Universal Serial Bus (USB)
transceiver that is fully compliant with the Universal
Serial Bus Specification Rev. 2.0. The USS810 can
transmit and receive serial data at full-speed
(12 Mbits/s) and low-speed (1.5 Mbits/s) data rates
and, therefore, can be used as either a USB device
transceiver or a USB host transceiver.

Since the USS810 operates at digital I/O voltages
between 1.75 V to 3.3 V, it is particularly suitable for
portable electronic devices such as mobile phones,
digital still cameras, personal digital assistants
(PDAs), and a variety of information appliances. This
transceiver provides an ideal interface to the physical
layer of the universal serial bus for application-spe-
cific ICs (ASICs) and programmable logic devices
(PLDs) with power supply voltages in the above
range.

The USB transceiver is currently available in an
MLCC16 package that supports single-ended input
data interface.

3 Suitable Applications

Portable electronic devices, such as the following:

Mobile phone

Digital still camera

Personal digital assistant (PDA)

Information appliances

Table 1. USS810 Pin Description

1. Symbol names with an overscore (e.g., NAME) indicate active-low signals.

Symbol

MLCC

Pin

Type

Description

PU(3.3)

Pull-Up Voltage Source. Connect this pin through an external 1.5 k

resistor to D+

(for full-speed operation) or D (for low-speed operation). This pin's function is
controlled by the SOFTCON input pin. To ensure zero pull-up current, set
SOFTCON = low to cause V

PU(3.3)

to float (high impedance); when

SOFTCON = high, V

PU(3.3)

= 3.3 V.

SOFTCON

Software-Controlled USB Connection. This pin allows USB connect/disconnect
signaling to be controlled by software. A high level on this pin applies 3.3 V to pin
V

PU(3.3)

, which is connected to an external 1.5 k

pull-up resistor.

Output Enable. This active-low pin enables the transceiver to transmit data on the
USB bus.

RCV

Differential Data Receiver. When the SUSPND input is high, this pin is driven low.
The state of RCV is unknown when FSE0 = 1.

Single-Ended D+ Receiver. The VP pin is used for external detection of single-
ended zero (SE0), error conditions, and speed of connected device.

Single-Ended D

- Receiver. The VM pin is used for external detection of single-

ended zero (SE0), error conditions, and speed of connected device.

SUSPND

Suspend. When SUSPND is high, it enables a low-power state while the USB is
inactive and drives output RCV to a low level. No dc power is consumed when
SUSPND is high.

GND

Device Ground.

DD(I/O)

Power Supply for Digital I/O. 1.75 V to 3.3 V.

SPEED

Speed Selection. This pin adjusts the slew rate of differential data outputs D+ and
D. Tie this pin low to enable low-speed data transmission (1.5 Mbits/s) and high to
enable full-speed data transmission (12 Mbits/s).

Analog

I/O

Negative USB Differential Data Bus. If this device is used in a USB peripheral
application, connect an external 24

± 1% resistor in series with this signal in

order to meet the USB Specification, Rev. 2.0 impedance requirement. Connect
this signal to pin V

PU(3.3)

via a 1.5 k

± 5% resistor for low-speed USB peripheral

applications.

D+

Analog

I/O

Positive USB Differential Data Bus. If this device is used in a USB peripheral
application, connect an external 24

± 1% resistor in series with this signal in

order to meet the USB Specification Rev. 2.0 impedance requirement. Connect this
signal to pin V

PU(3.3)

via a 1.5 k

± 5% resistor for full-speed USB peripheral appli-

cations.

Single-Ended Data Input. Refer to Table 3..

FSE0

Single-Ended Zero Mode. Refer to Table 3..

3.3 V Power Supply. This voltage supply is used for the USB signals D+/D and the
internal level shifter.

Not Usable. No external connections to this pin are allowed.

6.1 Function Selection

Table 2. Function Table

1. Signal levels on (D

+, D) are determined by other USB devices and external pull-up/down resistors.

2. In suspend mode (SUSPND = high), the differential receiver is inactive and output RCV is always low. Out-of-suspend (K) signaling is

detected via the single-ended receivers VP and VM.

3. In suspend mode, the D+/D output is tristated.

7 Limiting Values

7.1 Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of
those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
