Microchip PIC16F15344-I/SS 8-Bit Microcontroller Technical Overview and Application Guide
The Microchip PIC16F15344-I/SS stands as a versatile and robust member of the enhanced mid-range PIC16F family, engineered to deliver a powerful blend of core independent peripherals (CIPs), analog integration, and low-power operation. This 8-bit microcontroller (MCU) is housed in a 28-pin SSOP package, making it suitable for a wide array of embedded control applications, from consumer electronics and automotive subsystems to industrial automation and Internet of Things (IoT) nodes.
Core Architecture and Performance
At its heart, the PIC16F15344 is built upon an enhanced 8-bit RISC CPU core operating at up to 32 MHz, achieving a performance of 8 MIPS. This core is augmented with a 14-bit wide instruction set, offering improved code density. The device features 28 KB of Flash program memory and 2 KB of RAM, providing ample space for complex application code and data handling. A key feature enhancing its resilience is the Memory Access Partition (MAP), which supports bootloader and application separation for secure field updates.
Advanced Core Independent Peripherals (CIPs)
A defining characteristic of this MCU is its rich set of CIPs, which operate without constant CPU intervention, enabling deterministic and efficient system response. Key peripherals include:
Complementary Waveform Generator (CWG): Essential for advanced motor control and power conversion, it can generate non-overlapping complementary PWM signals with dead-band control.
Windowed Watchdog Timer (WWDT): Enhances system reliability by providing a configurable window for refresh, guarding against both hardware and software faults.
Peripheral Pin Select (PPS): Offers unprecedented flexibility in digital pin mapping, allowing designers to remap peripheral functions to different I/O pins, thereby optimizing PCB layout.
Multiple Communication Interfaces: It includes EUSART (UART), I2C, and SPI modules, facilitating seamless communication with a vast ecosystem of sensors, displays, and other ICs.
High-Fidelity Analog Integration
The PIC16F15344 excels in analog capabilities, reducing the need for external components. It integrates a 10-bit Analog-to-Digital Converter (ADC) with up to 35 channels, capable of performing measurements during Sleep mode for ultra-low-power sensing. Furthermore, it includes 5-bit Digital-to-Analog Converters (DACs) and two comparators, providing a complete signal chain solution on a single chip.
Low-Power Management
Designed for energy-sensitive applications, the MCU features multiple power-saving modes. The IDLE and DOZE modes allow peripheral operation while the core CPU is suspended or slowed down. The Peripheral Module Disable (PMD) feature allows designers to disable unused hardware peripherals, significantly reducing active power consumption.
Application Guide
The combination of these features makes the PIC16F15344-I/SS ideal for a multitude of applications:
Motor Control: The CWG, ADC, and comparators are perfectly suited for driving brushless DC (BLDC) and stepper motors in appliances, drones, and industrial tools.
IoT Endpoints: Low-power modes, ample memory, and communication peripherals enable the development of connected sensors that can operate for extended periods on battery power.
Automotive Body Electronics: Its robust design and temperature range (-40°C to +85°C) make it suitable for controlling lighting, window lifts, and other body control modules.
Consumer Products: From touch-sensing interfaces (supported by the Charge Time Measurement Unit (CTMU)) to general control tasks, it offers a cost-effective and highly integrated solution.
The Microchip PIC16F15344-I/SS is a highly integrated and flexible 8-bit microcontroller that successfully balances performance, power efficiency, and system cost. Its extensive suite of Core Independent Peripherals empowers designers to create complex, responsive, and reliable embedded systems with simplified software overhead. For engineers seeking a capable MCU for motor control, low-power IoT, or general-purpose automation, the PIC16F15344 represents a compelling and competitive choice in the embedded market.
