RF & MICROWAVE DESIGN Digital radio Rx chip gets approvals for worldwide reception standards Silicon Labs’ Si468x digital radio IC family now has additional options for AM and AM HD Radio. It is, the company says, the most cost-effective single-chip digital radio receiver available that supports worldwide radio reception and that is certified for the Digital Radio Tick Mark and AM/ FM HD Radio. Claimed as the first monolithic, CMOSbased antenna-input-toaudio output digital radio ICs, the Si468x receivers meet the needs of portable and consumer electronics products supporting digital radio standards including tabletop and clock radios, boom boxes, mini/micro audio systems, home theatre systems, docking stations, mobile phones, tablets and personal media players. The Si468x family features a low-power, multi-band receiver supporting global analogue and digital radio standards including AM, FM, FM RDS, AM/FM HD Radio, DAB and DAB+. The Si468x family is one of a few select receiver technologies to be approved by Digital Radio UK (DRUK) for the Digital Tick Mark. The Si468x receiver family integrates RF tuner, baseband and audio processing circuitry on a single die.A wafer-level chip-scale package (CSP) option enables a complete, compact radio receiver system with only 12 external components in under 100 mm². Silicon Labs www.silabs.com Bluetooth Smart MCU caters for high temperature range industrial applications TI’s SimpleLink Bluetooth low-energy CC2540T is a low power wireless microcontroller with an extended temperature range of -40C to 125C and USB connectivity for industrial applications. High-temperature Bluetooth Smart MCU for industrial and lighting applications The CC2540T is a complete solution, with TI’s BLE-Stack software and sample applications including over-the-air download support for in-field updates. Bluetooth Smart benefits industrial applications making it easier to get information and control systems via smartphone or tablet, bypassing more manual and often complicated systems. The CC2540T allows for lighting designs with high junction temperature and any other designs requiring to work in conditions above 85C; it has a 97dB link budget and is a true single-chip Bluetooth low energy solution with integrated MCU and RF; 256 kB of embedded Flash; and the royalty-free TI BLE-Stack protocol stack,profile software and sample applications. Use it in single-mode Bluetooth Smart sensor applications; a simplified design can have a one-chip, integrated and flexible solution. The SimpleLink Bluetooth low energy CC2540T wireless MCU is $2.30 (1000). A range of development tools is avaible. Texas Instruments www.ti.com Drop-in Bluetooth 4.0 module-on-module for control systems Toshiba has a development module-on-module (or “Module2”) that combines a Bluetooth 4.0 module with a microcontroller in order to shorten development times. The Module2 enables simple integration into sensor control systems, lighting and heating systems, PC peripheral systems and legacy host control systems. The Module2 measures 25 x 17 mm and is suited for battery driven applications. It comprises a Toshiba TMPM- 395FWAXBG ARM Cortex M3 core MCU along with a Panasonic PAN1026 Bluetooth 4.0 dual mode module, with antenna, that incorporates a Toshiba TC35661-501 Bluetooth LSI with embedded Bluetooth stack and SPP and BLE Gatt profiles. The Bluetooth module is programmable using high-level Bluetooth APIs and includes 128 kB NAND flash memory to store the Bluetooth host control and system application software. The device supports a range of hardware interfaces including UART, I2C, SPI and JTAG debugger interface. With pre-certified Bluetooth hardware and firmware, the module provides a simple path to Bluetooth SIG EPL listing. The MCU is bvased on an ARM Cortex M3 CPU core with an operating frequency of 20 MHz, 128 MB of internal ROM and 8 kB of internal RAM. It has independent RTC and IO capable of separating or shutting off power supplies and operates down to 1.8V. Toshiba will supply samples, full BoM and circuit diagrams to volume customers, as well as allowing them to utilise the design. Toshiba Electronics Europe www.toshiba-components.com Remote control IC includes voice control and smart-home management The GP565 Smart Home radio chip from GreenPeak Technologies for remote controls supports voice control, motion sensing and the ZRC 2.0 protocol. It is aimed at “next generation” remotes using RF instead of infrared (IR), to build a single remote for all Smart Home systems. The new Zig- Bee ZRC 2.0 protocol enables a single remote control to control all the home’s connected devices including turning on lights, opening curtains, managing appliances and environment, etc. Other new ZRC 2.0 features include the ‘Find My Remote feature, which enables a remote control to start beeping and/or flashing when it is lost and making it much easier to find. It can be activated by a physical Find My Remote button on the homes entertainment system or Smart Home devices. The IR-RF Download feature provides complete control of legacy audio and video equipment, either through RF4CE or infrared, with a hybrid remote control, without requiring the user to select the correct IR settings for the TV. ZRC 2.0 is fully backward compatible with existing ZRC 1.x implementations. The voice control features enables users to control the remote without having to navigate a confusing nest of buttons. This includes changing channels, searching for programs, activating DVR and other functions, as well as controlling other ZRC 2.0 connected devices in the home.
