Near Field Communication is starting to become commonplace with recent devices. They make transactions so much easier and energy efficient that almost every mobile OS designers offer apps or features that use NFC. The PN5180A0ET is a high-power output NFC frontend IC that runs at 13.56MHz. It uses outstanding modulation and demodulation concept completely integrated for all kinds of wireless communications.
The PN5180 ensures maximum interoperability for next generation of NFC enabled mobile phones. The PN5180 is optimized for point of sales terminal applications and implements a high-power NFC frontend functionality which allows to achieve EMV compliance on RF level without additional external active components.

Fabricated using the Philips 1.0 micron CMOS technology, the SC28L198 is low cost, high density and low power, making it a great choice for all sorts of UART applications. Boasting 8 full-duplex asynchronous channels, the single chip CMOS-LSI SC28L198 offers significantly deeper 16 byte FIFOs, automatic in band flow control and address recognition.
With over 22 fixed baud rates to choose from, you can independently select the speed of each receiver and transmitter. The ability to independently program the operating speed of the receiver and transmitter makes the Octal UART particularly attractive for dual speed full duplex channel applications such as clustered terminal systems. A power down mode is available where power consumption is greatly reduced due to the oscillator being stopped but register contents are still maintained.

If you’re looking for a well built, versatile, digital temperature sensor, the LM75B might just be what you need. The LM75B employs an on-chip band gap temperature sensor and Sigma-Delta A-to-D conversion technique with an overtemperature detection output. Also equipped with numerous data registers, the LM75B is able to store device settings like device operation mode, OS operation mode, OS polarity, OS fault queue, and many more.
The LM75B has a number of modes of operation such as normal mode, shutdown mode, two modes for OS output namely OS comparator mode and OS interrupt mode, giving you a wide array of possible uses and applications. And most importantly, between -25℃ to +100℃ an accuracy of ±2℃ is maintained. Even going up to the maximum levels of -55℃ to +125℃, an accuracy of ±3℃ can still be expected.

The CBTU4411EE is a 11-bit bus switch with each Host port pin multiplexed to one of four DIMM port pins. A decoder driven by three hardware select pins (S0, S1 and EN) control the selection of the DIMM port all of which are SSTL_18 compatible. The CBTU4411EE is designed to have only one DIMM port active at any time.
The part incorporates a very low crosstalk design. It has a very low skew between outputs (< 30 ps) and low skew (< 30 ps) for rising and falling edges. Each switch has been optimized for connection to 1- or 2-rank DIMMs. The low internal RC time constant of the switch allows data transfer to be made with minimal propagation delay.
The CBTU4411 is characterized for operation from 0 °C to +85 °C.
