Single-chip DECT ICs with QSPI flash interface
November 17, 2010 // Julien Happich
SiTel Semiconductor announced two single-chip DECT / CAT-iq ICs, the SC14441 and SC14442. Both chips feature a unique, low-power Quad Serial Peripheral Interface (QSPI) flash interface, allowing them to be used with external QSPI Flash memory ICs. This gives manufacturers the flexibility of a flash-based system, such as short time to market and in-field product upgrades, at a price point equivalent to ROM-based solutions.
SiTel's novel QSPI Flash interface is designed specifically for low-power applications and guarantees low current consumption. As a result, cordless phone manufacturers now have a third option for incorporating flash memory that was previously only available to consumer electronics applications.
It avoids the expensive processing of embedded flash or the costs of external parallel Flash. This brings the cost of flash-based systems down to a level comparable with ROM-based systems, without the long lead times associated with ROM code production.
Moreover, the QSPI interface has the advantage of allowing the use of very small packages, minimizing the amount of PCB space required and enabling the creation of compact, visually appealing end products. Available in a wide range of memory sizes, from 4 to 32 Mb, QSPI flash chips allow manufacturers to deliver a complete product portfolio from a single base PCB design. It also eliminates the need for separate EEPROM for storing user settings and phonebooks.
The SC14441 is supplied in a 96-pin LLGA package. Offering extra codec and I/O functionality, the SC14442 is housed in a 113-pin LLGA package.

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
