Microchip Technology Inc. has introduced the family of PIC18-Q41 and AVR DB MCUs that combined advanced analog peripherals and multi-voltage operation with inter peripheral connections, this provides increased system integration, reduced signal acquisition time, and more convenient and efficient operation in a single design environment.


The PIC18-Q41 MCU has been designed with a configurable Operational Amplifier (Op-Amp) and Analog-to-Digital Converter (ADC) with computation and Digital-to-Analog Converters (DACs), this helps in conditioning the signals for space-constrained sensing and measuring applications such as IoT end nodes and industrial, medical devices, wearable, automotive and lighting systems.


Offered in compact 14- and 20-pin packages, PIC18-Q41 MCU is suitable for IoT and large-scale artificial intelligence (AI) at-the-edge and they are a good companion to Microchip’s 32-bit MCUs and other controllers that require analog integration.


The AVR DB MCU simplifies the challenges of multiple power domains in the mixed-signal IoT systems and reduces the cost by integrating true bi-directional level shifters. Designed with three independent and highly configurable Op-Amps, a 12-bit differential ADC, 10-bit DAC, three zero-cross detectors, and Core Independent Peripherals (CIPs), the AVR DB MCU can be used in any applications involving analog signal conditioning and processing functions.


Both the PIC18-Q41 and AVR DB MCU product families are supported by Microchip’s MPLAB® X Integrated Development Environment (IDE), it's MPLAB Code Configurator (MCC), and the MPLAB Mindi™ Analog Simulator.
