Microchip Technology has released the PIC18-Q41 and AVR DB MCU families that are the first to combine advanced analog peripherals and multi-voltage operation with inter-peripheral connections for increased system integration and reduced signal acquisition times and offer the convenience and efficiency of operating in a single design environment.
“Microchip is bringing the 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.”
To address the need for signal conditioning in space-constrained sensing and measuring applications such as IoT end nodes and industrial, medical devices, wearable’s, 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 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.
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.
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 to start projects immediately.
