“Microchip is bringing easy-to-use analog capability to cost-effective PIC and AVR MCUs so designers can meet the requirements of large-scale IoT systems,” said Greg Robinson, associate vice president of marketing for Microchip’s 8-bit microcontroller business unit. “With a unified, seamless development tool experience, designers can use these MCUs as a single-chip controller, or as an intelligent analog signal conditioning component in a larger system.”

The PIC18-Q41 MCU offers a configurable op amp and ADC with computation and DACs. It comes in small 14- and 20-pin packages. The devices also works well beside Microchip’s 32-bit MCUs and other controllers that need analog integration.

The AVR DB MCU simplifies the challenges of designs that require multiple power domains and reduce cost by integrating true bi-directional level shifters. The device includes three independent, configurable Op Amps, a 12-bit differential ADC, 10-bit DAC, three zero cross detectors and Core Independent Peripherals (CIPs). This high level of integration makes the AVR DB MCU ideal for applications that need analog signal conditioning and processing functions.

Both the PIC18-Q41 and AVR DB MCU families are supported by Microchip’s MPLAB X IDE, MPLAB Code Configurator (MCC) and the MPLAB Mindi Analog Simulator. MCC provides a graphical interface to configure peripherals and functions specific to an application. AVR DB is also supported by Atmel START, Atmel Studio and third-party tools such as IAR and the GCC C compiler. MCC and START assist in the configuration of an Op Amp system for a wide varity of applications through a GUI without the need for coding.

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.
