Microchip Technology PIC16F18056 & PIC16F18076 8-Bit Microcontrollers

Microchip Technology PIC16F18056 and PIC16F18076 8-Bit Microcontrollers feature a suite of digital and analog peripherals that enable cost-sensitive sensor and real-time control applications. These MCUs are available in 28-pin to 44-pin packages with 28KB program Flash memory and speeds up to 32MHz. The PIC16F18056 and PIC16F18076 MCUs include a 10-bit Analog-to-Digital Converter with Computation (ADCC), automated Capacitive Voltage Divider (CVD) techniques for advanced capacitive touch sensing, averaging, filtering, oversampling and threshold comparison, and a charge pump in addition to an 8-bit Digital-to-Analog Converter (DAC) module.

The Microchip Technology PIC16F18056 and PIC16F18076 MCUs include three 10-bit Pulse Width Modulation (PWM) modules, Peripheral Pin Select (PPS), digital communication peripherals, timers, and waveform generators. These devices also provide memory features such as the Memory Access Partition (MAP) to support users in data protection and bootloader applications. Data EEPROM and a Device Information Area (DIA) that stores Fixed Voltage Reference (FVR) offset values help improve Analog-to-Digital Converter (ADC) accuracy.

The PIC16F18056 is available in 28-pin SPDIP, SOIC, SSOP, and VQFN packages. The PIC16F18076 is offered in 40-pin PDIP and QFN packages and a 44-pin TQFP package.
