Product Highlight

  • Type: Serial/UART (TTL,RS-232/422/485)
  • Core Supported: SP337

The SP337EBEY-0A-EB is a part of SP337EBEY series of development tool. It is a evaluation board for protocol transceiver.

The SP337E is a dual mode RS-232/RS-485/RS-422 serial transceiver containing both RS-232 and RS-485 line drivers and receivers. The RS-232 mode provides three drivers and five receivers to support all eight signals commonly used in the DB9 serial port connector (3TX/5RX). In RS-485 mode the device features two independent high speed RS-485 /422 transmit and receive channels (2TX/2RX). The default RS-485 configuration is full-duplex, but half-duplex operation can be obtained by tying together the TX and RI pins, and the TXEN and RXEN signals. The SP337 is pin compatible to Exar’s SP334.
