DESCRIPTION

The OXCF950 rev B is a low cost asynchronous 16-bit PC

card (henceforth referred to as PCMCIA) or Compact Flash

(henceforth referred to as CF) UART (and Local Bus)

device. Local Bus Selection is performed by use of a

MODE pin. Note that Local Bus mode uses indirect

addressing, which is only supported by PCMCIA.

128-deep transmitter and receiver FIFOs. Deep FIFOs

reduce CPU overhead and allow utilisation of higher data

rates.

It is software compatible with the widely used industry-

standard 16C550 type devices and compatibles, as well as

other OX16C95x family devices.

The 3.3V technology has been specified to operate as low

as 2.7 V to allow an in-line regulator to be used for mixed

3V/5V applications. All the I/Os are 5V tolerant with the

exception of the clock/crystal oscillator input.

In addition to increased performance and FIFO size, the

OXCF950 rev B also provides enhanced features including

improved flow control. Automated software flow control

using Xon/Xoff and automated hardware flow control using

CTS#/RTS# and DSR#/DTR# prevent FIFO over-run. Flow

control and interrupt thresholds are fully programmable and

readable, enabling programmers to fine-tune the

performance of their system. FIFO levels are readable to

facilitate fast driver applications.

The EEPROM interface allows the programming of the

Attribute Memory, UART and Local Configuration Registers

during power up or hard/soft reset. This allows different

card manufacturers to modify the information contained in

the Attribute memory or UART/registers as required, for

example PC-Card ID value.

The addition of software reset enables recovery from

unforeseen error conditions allowing drivers to restart

gracefully. The OXCF950 rev B supports 9-bit data frames

used in multi-drop industrial protocols. It also offers multiple

external clock options for isochronous applications, e.g.

ISDN, xDSL.

A number of power-down modes are included to keep

power consumption to a minimum. Such features include

clock division (fully programmable) and sleep modes when

a function of the OXCF950 rev B is not being used.

The OXCF950 rev B contains a single-channel ultra-high

performance UART offering data rates up to 15Mbps and
