IoT Computers Components Computers Electro Optic & Camera Packaging & Production Motion Automotive New Products and AVR® microcontroller (MCU) families are gaining market share. Over the past 50 years, the market for 8-bit MCUs has grown steadily and Microchip currently sells one device for every human in the western hemisphere each year. To support this ongoing trend, Microchip Technology Inc. (Nasdaq: MCHP) today announces the release of five new product families and over 60 new individual devices that offer embedded designers simple solutions to their most common problems. Designers who are looking to create innovative designs are turning to Microchip’s new product families of PIC and AVR MCUs because of their processing power, ability to easily communicate with other chips, and analog peripherals that have been built to be exceptionally configurable without having to make changes to the Printed Circuit Board (PCB). These devices combine ASIC-like capabilities with a simple development experience that extends traditional MCU capabilities and allows them to be configured as smart peripheral chips. Smart peripherals, like the software-controlled op amp found on the PIC16F171 family, the Multi- Voltage I/O (MVIO) and Analog-to-Digital Converter with Computation (ADCC) add value to applications that otherwise would not use traditional MCUs. The challenge of spanning multiple voltage domains is a common situation in systems that include chips using different supply voltages (e.g., connecting a 5V MCU to a 1.8V sensor). This type of system would normally require level-shifting hardware, which increases costs. The MVIO peripheral found on Microchip’s latest 8-bit MCUs, including the AVR DD family, allows a single port on the MCU to operate in a different voltage domain than the rest of the MCU, which eliminates the need for additional external components. Some systems require a level of speed and response time that is difficult to achieve with software-based processing. The Core Independent Peripherals (CIPs) available across the Microchip PIC and AVR product range can be programmed with MPLAB® Code Configurator (MCC) to be easily connected to form a hardware processing chain. This makes it possible to create custom peripherals that eliminate software processing cycle times. For example, a WS2812 LED array, which requires unique timing to be driven correctly, can be controlled easily by configuring a super peripheral consisting of a Pulse-Width Modulator (PWM), an SPI

The modules can switch between this mode and full output regulation at a pre-set input voltage, to limit total variation of output voltage. As a result, both new variants feature improved efficiency of up to 97.5% at 50% load. Output voltages are centered around 12 V for input ranges that include 48-56 V and 40-60 V for data center applications. The BMR4912307/856 variant has a reduced height of 13.4 mm for space-constrained applications. Both variants include an Event Data Recorder function or “Black Box” which captures key date-stamped operational parameters during a shutdown event for easy fault tracing and failure analysis. All BMR491 modules feature an operational temperature range of -40°C to +125°C, 1500 V input-output ‘basic’ isolation complying with IEC/EN/UL 62368-1, and full protection against over over-temperature, input under- voltage and output over-voltage, over-current and short circuits. A 4-pin PMBus® digital interface is provided, and the products are supported by the freely available ‘Flex Power Designer’ software for remote configuration, control and monitoring. Anders Sellin, Product Manager of Flex Power Modules comments “More and more customers are asking us for peak power handling capabilities to support ever more dynamic loads, and we are responding with several solutions now including the BMR491 series. Employing our HRR technique makes them even more efficient as well – a winning combination”. All variants are available in OEM quantities.
