The SmartBond DA14585 BLE SoC is designed by Dialog Semiconductor for use in TPMS sensors in the automotive industry. For example, the SoC can be utilized as an electronic subsystem for monitoring air pressure and temperature within automobile tires, alerting drivers of improperly-inflated tires or other safety information in real time. The SoC replaces, typical TPMS sensors using proprietary or non-standard sub-GHz radios to transfer information to the automobile’s computer. The SoC handles the entire processing required for building a BLE-enabled TPMS application, with no additional MCU needed. Further benefits include high security, upgradable firmware and connectivity to automobile computers via a single node for all BLE functions.
Available for purchase through Avnet, Digi-Key and Mouser, the SmartBond DA14585 BLE SoC supports standalone as well as hosted applications and comes with a complete development environment including SmartSnippets software, which helps profile and fine tune power consumption.

Built by Intersil to interface with the latest generation of automotive SoCs, the TW884x HD 1080p LCD processor with analog video decoder and two scalers provides the reliability required to ensure rearview camera systems are compliant with FMVSS-111 for preventing backover accidents. Live video is displayed with graphics overlay in less than 0.5 seconds after vehicle ignition. SoC and camera output is monitored to determine if they are in a frozen or corrupted state. If issues are detected, the SoC is bypassed and the rearview camera video is instantly displayed.
The video processor can be combined with Renesas’ R-Car SoC family, as well as the ISL78302 dual LDO, ISL78322 dual 2 A / 1.7 A synchronous buck regulator, ISL78228 dual 800 mA synchronous buck regulator, and other automotive infotainment system board components. Available now in 14 x 20 mm, 156-lead LQFP packaging, the video processor comes in two models: the TW8844 with MIPI-CSI2 output is priced at $10.00 each/1,000 and the TW8845 with BT.656 output is $9.50 each/1,000.
Infineon Technologies’ new high performance, low noise MEMS microphones, IM70A135 (analog) and IM69D130 (digital), are based on the company’s dual backplate MEMS technology. They feature a 70 dB SNR combined with a 10% at a 135 dB SPL distortion level. In a 4 x 3 x 1.2 mm MEMS package, the microphones are suited for high-quality acoustic recordings and far field voice capturing applications.
The dual backplate MEMS technology uses a membrane embedded within two backplates to generate a truly differential signal, allowing improved high frequency immunity for better audio signal processing and increasing the acoustic overload point of 10% THD to 135 dB SPL. The analog and digital microphones provide ±1 dB sensitivity matching and ± 2° phase matching suitable for implementing in arrays and targeting ultra-precise beam forming and noise cancelling.
Engineering samples of the low noise packaged IM70A135 and IM69D130 MEMS microphones will be available in Q4/2017. Start of production will be in Q1/2018.
