SP330E RS-232/RS-485/RS-422 TRANSCEIVER WITH 1.65V-5.5V INTERFACE November 2013 Rev. 1.0.0 GENERAL DESCRIPTION The SP330 is an advanced multiprotocol transceiver supporting RS-232, RS-485, and RS-422 serial standards and featuring a variable low voltage logic interface, down to 1.65V. Full operation requires only four external charge pump capacitors. The RS-485/RS-232 mode pin selects RS-485 mode when high, and RS-232 mode when low. In RS-485 mode the HALF/FULL pin configures the transceiver as either half or full duplex. The high speed drivers operate up to 20Mbps in RS485/422 modes, and up to 1Mbps in RS-232 mode. All drivers can be slew limited to 250kbps in any mode to minimize electromagnetic interference (EMI) by setting the dedicated SLEW pin low.
