PRODUCT SHOWCASE New microcontrollers from Microchip help with analog system design Sensor-based Internet of Things (IoT) applications rely on a combination of analog functionality and digital control capability to meet a list of requirements including cost, size, performance and power usage. Addressing this through a focus on increased microcontroller (MCU) integration, Microchip Technology announced the PIC18-Q41 and AVR DB MCU families (as seen on page 82 of this issue). These are the first to com- bine advanced analog peripherals and multi-voltage operation with interperipheral connections for increased system integration and reduced signal acquisition times. To address the need for signal conditioning in space-constrained sensing and measuring applications (such as IoT end nodes and industrial, medical devices, wearables, automotive and lighting systems), the PIC18-Q41 MCU has a configurable operational ampli- Microchip Technology Inc.

These can now be downloaded from digikey.com With this collaboration, engineers can access SnapEDA’s high-quality CAD models directly on Digi-Key’s website, further streamlining their design flow. To start downloading EDA and CAD parts from Digi-Key, go to a part detail page, look for the row labelled "EDA / CAD Models" and click on Download from SnapEDA. Supported formats include Altium, Eagle, KiCad, OrCad, Allegro, PADS, and DXDesigner. Novus NP400 two-wire pressure sensors break the $100 barrier. These compact sensors are ideal for air and water applications. They feature a wide power supply range of 11-33V DC, ±0.5% accuracy, an overpressure range (twice the maximum range) and rupture pressure (triple the pressure range upper value). Process connections: external thread ¼ NPT, ¼ G, ½ NPT or ½ BSP. ► siliconchip.com.au fier, analog-to-digital (ADC) & digitalto-analog converters (DAC). It is particularly well-suited for IoT and large-scale artificial intelligence (AI), including predictive maintenance edge nodes in a smart factory. Offered in compact 14- and 20-pin packages, the PIC18-Q41 MCU also makes a good companion to Microchip’s 32-bit MCUs and other controllers that require analog integration. Mixed-signal IoT systems often include multiple power domains, and the AVR DB MCU simplifies these designs while reducing cost by integrating true bi-directional level shifters. This feature lowers cost in a wide range of applications such as automotive, HVAC and liquid measurement. The addition of three independent and highly configurable op amps, a 12-bit differential ADC, 10-bit DAC, three zero cross detectors and core independent peripherals (CIPs) makes the AVR DB MCU ideal for virtually any application involving analog signal conditioning and processing functions. SnapEDA adds millions of parts to its library each year, aided by its computer vision technology such as InstaBuild, and other automation tools. Supported suppliers on SnapEDA include Recom, CUI, Samtec, TE Connectivity, I-PEX, GCT, CUI Devices, Bel Fuse, Murata, Texas Instruments, ECS, Triad Magnetics, Quectel, Infineon and many more. SnapEDA is on a mission to help engineers innovate faster by removing barriers. They help over one million engineers find CAD models for their electronics designs each year. Their community of professional engineers are making everything from medical devices to electric airplanes.
