PIN ASSIGNMENTS
Pin 1 — RERR — Receive Error. This CMOS
level output pin is forced HIGH when
both D+ and D- are HIGH to signal an
error state. CAUTION: Since RERR is a
CMOS output, care must be taken to
ensure that RERR is NOT connected to
V
CC or GND.
Pin 2 — OE — Output Enable Not. When
asserted LOW, this input pin enables the
driver to transmit data on the bus. When
HIGH, the receiver is active and the driver
outputs are in tri-state.
Pin 3 — RCV — Receive data. This is a
CMOS level output pin from D+ and D-,
typically connected to the inputs of the
USB Serial Interface Engine (SIE).
Pin 4, 5 — VP, VM — Gated version of D+
and D-. Used to detect single ended zero
(SEO), error conditions, and interconnect
speed. These pins have CMOS level
outputs.

Pin 6 — SUSPND — Suspend. This input pin
provides a low power state for the SP5301
while the USB bus is inactive. While the
SUSPND pin is asserted HIGH, it will
drive RCV pin LOW.
Pin 7 — GND — Ground.
Pin 8 — RSEO — Receive Single Ended Zero.
This CMOS level output pin is forced
HIGH when both D+ and D- are LOW to
signal the end of packet (EOP) in signal
transmission. CAUTION: Since RSEO
is a CMOS output, care must be taken to
ensure that RSEO is NOT connected to
V
CC or GND.
Pin 9 — SPEED — Speed. Edge rate control.
This input pin determines edge rates, where
a logic HIGH designates edge rates for
"full speed" and logic LOW designates
edge rates for "low speed."
Pin 10, 11 — D-, D+ — Data-, Data+. These
differential data bus I/O pins conform to
the Universal Serial Bus standard.
Pin 12, 13 — VPO, VMO — These are the
PINOUT
logic inputs to the differential driver,
typically connected to the outputs of the
Serial Interface Engine (SIE).
Pin 14 — V
CC — +3.0V to +3.6V power supply.
