Microchip PIC16F15345-I/SO 8-Bit Microcontroller Overview and Application Guide

The Microchip PIC16F15345-I/SO is a versatile 8-bit microcontroller unit (MCU) from Microchip Technology’s enhanced mid-range PIC® MCU family. Built on the robust PIC16 core architecture with a hardware multiplier, this device combines performance, peripheral integration, and power efficiency, making it a compelling solution for a wide array of embedded control applications. Housed in a compact SOIC (SO) package, it is well-suited for space-constrained designs.

Core Features and Architecture

At its heart, the PIC16F15345 operates at up to 32 MHz, delivering a balanced mix of processing power and low power consumption. It features 14 KB of Flash program memory and 1024 bytes of RAM, providing ample space for application code and data handling. A key strength of this MCU lies in its advanced peripheral integration. It includes a 10-bit Analog-to-Digital Converter (ADC) with up to 35 channels, enabling extensive sensor interfacing and system monitoring capabilities.

The microcontroller is further equipped with multiple communication interfaces, including EUSART, I2C, and SPI modules, ensuring seamless connectivity with other ICs, sensors, and peripherals. For timing and control tasks, it offers several timers (Timer0-Timer6), Complementary Waveform Generator (CWG), and Capture/Compare/PWM (CCP) modules, which are essential for motor control, power conversion, and generating precise waveforms.

Notable Peripherals: Core Independent and Intelligent

A standout feature of the PIC16F15345 is its suite of Core Independent Peripherals (CIPs). These peripherals, such as the Configurable Logic Cell (CLC), Peripheral Pin Select (PPS), and Hardware Limit Timer (HLT), can operate autonomously from the core. This allows them to perform complex tasks like logic operations, signal routing, and timing without CPU intervention, significantly boosting system efficiency and responsiveness while reducing power consumption.

Application Guide

The integration of analog, control, and communication peripherals makes the PIC16F15345-I/SO ideal for numerous applications:

Industrial Control: Factory automation, sensor nodes, and human-machine interfaces (HMIs) benefit from its robust I/O, communication links, and noise immunity.

Consumer Electronics: Appliances, power tools, and personal care products utilize its PWM for motor control and ADC for user input sensing.

Automotive: Suitable for body electronics modules, such as lighting control and access systems, leveraging its CIPs and reliability.

Internet of Things (IoT): Its low-power capabilities and communication peripherals make it a fit for simple, connected edge nodes.
