Microchip Technology has announced the PIC18-Q41 and AVR DB MCU families that combine advanced analog peripherals and multi-voltage operation with inter-peripheral connections. These enable increased system integration and reduced signal acquisition times, and offer the convenience and efficiency of operating in a single design environment, says Microchip.
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 op amp and ADC with computation and DACs. It is particularly well-suited for IoT and large-scale artificial intelligence (AI) at-the-edge, 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, according to Microchip.
Mixed-signal IoT systems often include multiple power domains, and the AVR DB MCU simplifies the challenges of these designs while reducing cost by integrating true bi-directional level shifters. This feature lowers cost in a wide range of applications including automotive, appliances, 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.
The PIC18-Q41 and AVR DB MCU product families are supported by Microchip’s MPLAB X Integrated Development Environment (IDE), its MPLAB Code Configurator (MCC) and the MPLAB Mindi Analog Simulator. MCC is a free software plug-in that provides a graphical interface to configure peripherals and functions specific to an application. In addition to MCC, the AVR DB is supported by Atmel START, Atmel Studio and third-party tools such as IAR and the GCC C compiler. MCC and START help analog and digital designers easily configure an op amp system for various typical use cases through a graphical user interface with no coding required.
Both MCU families offer a compact, cost-effective development board with programming and debugging capabilities: the PIC18F16Q41 Curiosity Nano Evaluation Kit (EV26Q64A) and the AVR DB Curiosity Nano Evaluation Kit (EV35L43A). Quick start guides for the PIC MCU and the AVR MCU are available now.
The PIC18-Q41 and AVR DB MCUs are offered in a range of memory sizes, packages and price points. The PIC18-Q41 pricing starts at $0.65 in 10,000-unit quantities. The AVR DB pricing starts at $0.95 in 10,000-unit quantities.
