Compact UARTs save 70% PCB space

20 October 2004 Design Automation

Designed for space-constrained applications, Royal Philips Electronics’ has expanded its family of 16C universal asynchronous receiver/transmitters (UARTs) with four new devices in compact lead-free HVQFN ­packaging. The SC16CxxB single- and dual-channel UARTs are suited for advanced portable and electronic systems requiring high speed, low voltage, low power use and high data rates.

According to Philips, its SC16CxxB UARTs in 32-pin HVQFN provide up to 70% PCB space savings compared to conventional packages and operate at low power – 2,5, 3,3 or 5V. These space savings are possible due to the unique design of the HVQFN package which decreases the footprint to near chip-scale size by removing the perimeter leads. The devices also feature high performance data rates of up to 5 Mbps, allowing throughput of data going to channel to be faster.

The compact UARTs are software ­compatible with Linux and Windows OS drivers, which saves development time and speeds time-to-market using industry-standard software. The devices have an extended temperature range of -45 to +85°C and a typical sleep current of 50 μA.
