OXCF950
Overview
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.
- Single full-duplex asynchronous channel 128-byte deep transmitter / receiver FIFO Fully software compatible with industry standard 16C550 type UARTs Readable FIFO levels System clock up to 60MHz Flexible clock prescaler from 1 to 31.875 9-bit data framing as well as 5,6,7 and 8 Detection of bad data in the receiver FIFO Automated in-band flow control using programmable Xon/Xoff characters Transmitter and receiver can be disabled Low power CMOS 3.3V operation, 5V tolerant I/O Extended temperature range -40C to +105C Software compatible with OXCF950 16C950 mode for local bus applications Generic embedded driver compatibility mode * * * * * * *
- Programmable by external MicrowireTM EEPROM (EEPROM programmed via Oxford Semiconductor utilities). Extremely low power consumption by use of asynchronous UART core and power down (sleep) modes Range of packages -Ultra small 48 pin TQFP package or a 48 ball TFBGA. Supports all UART types 450 up to 950 (fully programmable) CF+ Compliant (Revision 1.4). 16-bit PC Card Compliant (PCMCIA Revision 7.1) 8 bit Local Bus interface included for PCMCIA applications 2 Multi- purpose I/O pins which can be configured as interrupt inputs
