Microchip Technology PIC16F18156/76 Full-Featured 28-/40-Pin MCUs

Microchip Technology PIC16F18156 and PIC16F18176 Full-Featured 28-/40-Pin MCUs feature a memory range of 7KB to 28KB with speeds up to 32MHz and a suite of analog peripherals to enable precision sensor applications. These MCUs include a 12-bit differential Analog-to-Digital Converter with Computation (ADCC), two 8-bit Digital-to-Analog Converters (DAC), a 16-bit Pulse-Width Modulation (PWM) peripheral, and many more waveform control/communication peripherals. The small form-factor, feature-rich devices are well suited for low-cost, energy-efficient analog sensor applications with higher resolution requirements.
