General

 The BB16CF950+ is a UART (Universal Asynchronous Receiver-Transmitter) with a host interface suitable for direct connection to a CompactFlash or 16-bit PC Card bus. Once installed and configured by the host OS, it provides an eight-byte programming interface which may be configured to be identical to that of the TL16C750 UART from Texas Instruments. It can be configured to fit the requirements of RS232, RS422/485, or Bluetooth® applications.

Key features

Glueless interface to CompactFlash or 16-bit PC Card (PCMCIA) bus

UART is register and functionally compatible with TL16C750

Compatible with existing 16C750/550/450 device drivers

Wide supply voltage range 3.0-5.5V

Compliant with stringent CompactFlash I/O requirements

Low-power design

Configuration and CIS data is held in a small, cheap serial EEPROM

UART enhancements:

• 128-deep receive and transmit FIFOs
• Readable FIFO levels and tuneable trigger levels improve device driver performance
• Programmable “synchronisation factor” allows baud rates up to fclock/4
• Automatic transmitter/receiver enable control capability for RS485 half-duplex applications
• Extensions to standard register set are implemented in a safe, easy-to-use way

Added features for Bluetooth designs:

• Designed to support Bluetooth ICs from CSR’s BlueCore range
• Low-voltage interface pins eliminate the need for level-shifting circuitry
• SPI mode for factory-programming of BlueCore flash memory
• Power control can shut down power to Bluetooth circuitry when not in use
• Automatic reset generation after Bluetooth power-up
