The OXCFU950 is a low-cost, synchronous 16-bit PC Card
(PCMCIA) or CompactFlash/CF+ to UART and USB host
controller. It combines the high performance of Oxford
Semiconductor OX16C95x UART technology with USB
host capabilities. The inclusion of both a UART and USB
make the OXCFU950 ideal for wireless data cards.
The OXCFU950 integrates an OHCI-based USB host
controller, which supports a single USB port via the
integrated transceiver. An 8-Kbyte memory provides an
efficient interface for buffer and control structures between
the USB controller and the device driver.
The attribute memory, UART and USB registers can be
programmed via the internal EEPROM during power up or
hard/soft reset, allowing different card manufacturers to
customize information contained in the attribute memory or
UART/USB registers, for example PC Card ID value.
The 3.3-V technology has been specified to operate as low
as 2.85 V to allow an in-line regulator to be used for mixed
3-V/5-V applications. CF/PC Card pins are 5-V tolerant and
the variable I/O voltage to the UART/MIO pins eases the
connection to application chipsets.
A number of power-down modes are included to minimize
power consumption, including sleep modes for when a
device function is not being used.
The OXCFU950 contains a single-channel ultra-high
performance OX16C95x UART offering data rates up to
12 Mbps and 128-byte deep transmitter and receiver
FIFOs. Deep FIFOs reduce CPU overhead and allow
utilization of higher data rates.
The OXCFU950 USB controller supports OHCI-compliant
host stack software (available from Oxford Semiconductor).
The OXCFU950 UART is software-compatible with the
widely-used industry-standard 16C550 type devices and
compatibles, as well as other OX16C95x family devices.

Description
PC Card/CompactFlash address bus, bits [10:0]
PC Card/CompactFlash data bidirectional bus.
Register select and I/O enable.
Active-low card enable.
Active-low output enable used to gate memory read data (attribute
memory). Host must negate the OE# signal during write operations.
Active-low write enable used for strobing memory write data (attribute
memory).
Active-low I/O read enable.
Active-low I/O write enable.
Write protect (in memory-only mode).
IOIS16#
Data is 16-bit (in I/O & memory mode).
19
I_C_33_5_S_
RESET
PC Card/CompactFlash reset.
Note : This pin requires an external reset pulse generator (RC network)
to allow for the startup time for the internal oscillator and PLL.
24
O_T_33_2
READY
Device ready (in memory-only mode).
IREQ#
Active-low Interrupt request (in I/O & memory mode). Indicates to the
host system that the PC Card/CF requires host software service. Note:
interrupt can support level or pulsed types.
12
O_T_33_2
BVD1
Battery voltage detect 1 (in memory-only mode). Not supported so held
static.

58 O_T_33_1
STSCHG#
PCMCIA_VDD3V3
Active-low status-changed pin (in memory & I/O mode). Used to alert the
host system that the card status has changed. In this case it means that
a function’s ready state has changed. The host should check this by
considering each function’s PRR.
Connected internally.
SOUT
UART serial data output.
IrDA_Out
UART IrDA data output when MCR[6] is set in enhanced mode.
53
I_C_33_5_N_
SIN
UART serial data input.
IrDA_In
UART IrDA data input when IrDA mode is enabled (see above).
56
I_C_33_5_N_
DCD#
Active-low modem data-carrier-detect input.
60
O_T_33_1
DTR#
Active-low modem data-terminal-ready output. If automated DTR# flow
control is enabled, the DTR# pin is asserted & deasserted if the receiver
FIFO reaches or falls below the programmed thresholds.
485_En
In RS485 half-duplex mode, the DTR# pin may be programmed to reflect
the state of the transmitter empty bit to control the direction of the RS485
transceiver buffer automatically (see register ACR[4:3]).
59
O_T_33_1
RTS#
Active–low modem request-to-send output. If automated RTS# flow
control is enabled, the RTS# pin is de-asserted & reasserted when the
receiver FIFO reaches or falls below the programmed thresholds.
54
I_C_33_5_N_
CTS#
Active-low modem clear-to-send input. If automated CTS# flow control is
enabled, upon de-assertion of the CTS# pin the transmitter completes
the current character & enters idle mode until the CTS# pin is
reasserted. Note: flow control characters are transmitted regardless of
the state of the CTS# pin.
