The OXCF950 rev B

      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. It is software compatible with the widely used industrystandard 16C550 ty pe devices and compatibles, as well as other OX16C95x family devices. The OXCF950 rev B fixes all known errata of the OXCF950 part. It also adds two new modes of operation. The first mode (pin or EEPROM selectable) allows the device to function in embedded systems and The second mode (pin selectable) allows the device to act as a standalone 16C950 type part with the benefits over the 16C950 rev B of 5V tolerance.
     The OXCF950 rev B has following features. The 1st one is about single full-duplex asynchronous channel.The 2nd one is about 128-byte deep transmitter / receiver FIFO.The 3rd one is about Fully software compatible with industry standard 16C550 type UARTs.The 4th one is about Readable FIFO levels.The 5th one is about System clock up to 60MHz.The 6th one is about Flexible clock prescaler from 1 to 31.875.The 7th one is about 9-bit data framing as well as 5,6,7 and 8 .The 8th one is about Detection of bad data in the receiver FIFO. The 9th one is about Automated in-band flow control using programmable Xon/Xoff characters.The 10th one is about Transmitter and receiver can be disabled.The 11th one is about Low power CMOS.The 12th one is about 3.3V operation, 5V tolerant I/O.The 13th one is that the extended temperature range is from 40 to +105.The 14th one is about Software compatible with OXCF950.The 15th one is about 16C950 mode for local bus applications.The 16th one is about Generic embedded driver compatibility mode.The 17th one is about Programmable by external MicrowireTM EEPROM(EEPROM programmed via Oxford Semiconductor utilities).The18th one is about Extremely low power consumption by use of asynchronous UART core and power down (sleep) modes.The 19th one is about Range of packages -Ultra small 48 pin TQFP package or a 48 ball TFBGA.The 20th one is about Supports all UART types 450 up to 950 (fully programmable).The 21st one is about CF+ Compliant (Revision 1.4).The 22nd one is about 16-bit PC Card Compliant (PCMCIA Revision 7.1).The 23rd one is about 8 bit Local Bus interface included for PCMCIA applications.The last one is about 2 Multi-purpose I/O pins which can be configured as interrupt inputs.
