Integrated low-power analog features reduce system cost, size, and power consumption
Microchip Technology has announced the launch of its new PIC16F17576 microcontroller (MCU) family, designed to simplify the development of applications that require fast, accurate analog signal measurements—especially in battery-powered environments.
MCUs feature advanced low-power analog peripherals, including a unique combination of low-power comparators and voltage references that continue operating even when the MCU core is in sleep mode. This enables continuous analog signal monitoring while drawing less than 3.0 µA of current, helping developers maximize battery life.
The key features are:
- Four op amps with dynamic gain ladder
- Low-power voltage reference (VREFLP)
- 1.8–5.5V operating voltage range
- Adjustable internal oscillator (up to 32 MHz)
- Fast comparator (50 ns response time)
- 12-bit Differential ADC with Computation (ADCC)
At the heart of these MCUs is an Analog Peripheral Manager (APM), a key innovation that dynamically controls peripheral activity to minimize total power consumption. With integrated operational amplifiers (op amps) featuring software-selectable gain settings, the devices can maintain precision while managing noise across a range of input signals—using fewer external components. Up to four op amps and a 12-bit differential ADC with automatic averaging allow for highly accurate and flexible signal acquisition.Targeted at industries such as environmental and industrial monitoring, smart home technology, and building automation, the PIC16F17576 family is ideal for applications like vibration and strain sensing, flow metering, gas detection, cold asset tracking, and motion detection.
“Sensor designs often involve complex analog circuitry that adds cost, board size, and power demand,” said Greg Robinson, Corporate Vice President of Microchip’s MCU business unit. “Our new PIC16F17576 MCUs integrate essential analog features into a single, low-power device, dramatically simplifying designs and cutting overall system costs.” MCUs are available now, starting at $0.57 each in 10,000-unit quantities.
