Microchip PIC16LF15355-I/SS 8-Bit Microcontroller Technical Overview and Application Guide

The Microchip PIC16LF15355-I/SS is a versatile 8-bit microcontroller from Microchip’s enhanced mid-range PIC16F family, designed for low-power and cost-sensitive embedded applications. Combining robust processing capabilities with a rich set of integrated peripherals, this MCU is engineered to deliver high performance and flexibility in a compact 28-pin SSOP package.

Built around an enhanced 8-bit RISC CPU core operating at up to 32 MHz, the PIC16LF15355 leverages a 14-bit wide instruction set for efficient code execution. It features 16 KB of Flash program memory and 2 KB of RAM, providing ample space for embedded applications. A key strength of this microcontroller is its ultra-low-power architecture, supporting a wide operating voltage range from 1.8V to 3.6V, making it suitable for battery-powered and energy-harvesting applications.

The peripheral set is comprehensive and tailored for diverse connectivity and control tasks. It includes multiple communication interfaces such as EUSART, I2C, and SPI modules, enabling seamless interaction with sensors, displays, and other peripherals. The device also incorporates analog capabilities like a 10-bit ADC with up to 35 channels, multiple comparators, and a 5-bit DAC, facilitating precise analog signal acquisition and processing.

For timing and control, the MCU offers multiple PWM outputs, Capture/Compare/PWM (CCP) modules, and hardware limit timers. Enhanced safety and system reliability are supported through features like the Windowed Watchdog Timer (WWDT), Cyclic Redundancy Check (CRC) memory scan, and hardware brown-out reset (BOR).

Development is accelerated using Microchip’s MPLAB X IDE and MPLAB Code Configurator (MCC), which simplify code generation and peripheral initialization. The PIC16LF15355 is well-suited for applications including consumer electronics, IoT nodes, industrial control, and portable medical devices.
