'Smallest' multiprotocol transceiver unveiled
1 min read
Measuring just 5 x 5mm2, Exar's SP335 multiprotocol transceiver is claimed to be less than half the size of comparable discrete designs.
As well as doubling the number of serial interface channels that can be assembled in the same board space, the company says this allows system designers to combine multiple serial protocols over the same connector.
What's more, programmable end of line termination and multiple configuration modes allow all three protocols to be used interchangeably over a single cable or connector with no additional switching components.
The SP335's bus pins are protected against severe ESD events exceeding ±15kV IEC 61000-4-2 Air gap discharge, and ±8kV IEC 61000-4-2 contact discharge, and can tolerate direct shorts to DC or AC voltages as high as ±18V.
The transceiver also features a separate supply voltage for the logic interface pins, allowing the part to directly interface with low voltage UARTs and MCUs without needing voltage translators or level shifters. The logic supply voltage can be as low as 1.65V.
