RSB RS232 Serial Data Buffer ICs

The RSB family of RS232 serial buffers are designed specifically for capturing small bursts of serial from peripheral devices like modems, GPS receivers, RADAR units, etc. They store information internally until the host processor is ready to receive and process the information. RSB serial buffers are of greatest benefit when the host is "bit-banging" a serial port either because the host processor has no background serial reception capability or if that capability has already been devoted to another serial task.

Processors like Parallax's BASIC STAMP are greatly enhanced by the RSB buffer which allows the STAMP to do other things yet still receive asynchronous serial data. Conventional processors like the HC11 or 80C51 can also benefit from the RSB buffers where packet addressing is required or where the built in ASIC port is devoted to receiving other serial streams.

Features:

  • Receive serial data in background
  • Requires only one processor pin for bi-directional interface
  • Full peripheral side handshake at either full or not empty
  • Two RSB509C devices can be interfaced on one host I/O pin
  • Eight RSB6505 devices can be interfaced on one host I/O pin
  • RSB6505 has full handshake control on host side.
  • 32 bytes buffer for RSB509
  • 64 bytes buffer for RSB6505
  • Addressable packet modes
  • Line buffer and transmit mode for STAMPs SERIN statement in RSB6505
  • RSB6505 has straight through mode for cascading devices which multiplies buffer capacity
  • RSB6505 has pin strapping mode to set baud rate which requires no setup from host

 

RSB6505


RSB6505 Serial Data Buffer

P/N#: RSB6505A

Price: $7.95

The RSB6505 serial data buffer receives RS232 serial input and temporarily stores up to 64 bytes. A host processor, connected via a single serial line, can retrieve data when it has the time to process it. The RSB6505 may be jumper configured and act as a handshake controlled buffer for situations where a host processor is not required. Up to Eight RSB6505 devices may share a single host interface pin and be addressed independently by the host. The device address is set by pin strapping.

RSB509C-0 or RSB509C-1


RSB509C Serial Data Buffer

P/N#: RSB509C-X

Price: $7.95

The RSB509 serial data buffer receives RS232 serial input and temporarily stores up to 32 bytes. A host processor, connected via a single serial line, can retrieve data when it has the time to process it. Two RSB509C devices may share a single host interface pin and be addressed independently by the host. The device address is internal and specified by the final digit of the part number as either a 0 or a 1.
