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 Amplifier (Op Amp) and Analog-to-Digital Converter (ADC) with computation and Digital-to-Analog Converters (DACs). It is intended 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 analogue integration.
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 analogue 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 analogue 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).
