The Microchip PIC16F15354T-I/ML is a versatile 8-bit microcontroller from Microchip Technology's enhanced mid-range PIC16F family. Housed in a compact 28-pin QFN (5x5mm) package, this device is engineered for a wide array of embedded control applications, balancing performance, power efficiency, and cost-effectiveness. Its robust feature set makes it a compelling choice for designers across various industries.
Key Features and Capabilities
At its core, the PIC16F15354T-I/ML is built upon an enhanced Harvard architecture with a 49-instruction set, operating at a maximum frequency of 32 MHz, delivering up to 8 MIPS of performance. It is equipped with 14 KB of Flash program memory and 1024 bytes of RAM, providing ample space for complex firmware.
A standout feature of this MCU is its advanced peripheral set designed to minimize CPU intervention and boost system efficiency:
Core Independent Peripherals (CIPs): These are hardware-based modules that operate autonomously. Key CIPs include:
Complementary Waveform Generator (CWG): Crucial for precise motor control and power conversion applications, it can generate non-overlapping complementary PWM signals with dead-band control.
Windowed Watchdog Timer (WWDT): Enhances system reliability by offering configurable window settings for reset generation.
Numerically Controlled Oscillator (NCO): Provides a highly linear frequency source for applications like LED dimming or tone generation.
Analog Integration: The microcontroller incorporates a 10-bit Analog-to-Digital Converter (ADC) with up to 21 channels, a 5-bit Digital-to-Analog Converter (DAC), and two comparators. This high level of analog integration reduces the need for external components, simplifying board design and lowering the overall Bill of Materials (BOM).
Communication Interfaces: It supports multiple standard serial communication protocols, including I2C, SPI, and EUSART (Enhanced Universal Synchronous Asynchronous Receiver Transmitter), facilitating easy connectivity with sensors, memories, and other peripheral devices.
Low-Power Management: Featuring NanoWatt XLP technology, the device is optimized for battery-powered and low-power applications, offering multiple sleep modes and rapid wake-up times to extend operational life.
Primary Applications
The integration of these features enables the PIC16F15354T-I/ML to excel in numerous markets:
Automotive: Ideal for body electronics modules, such as lighting control, interior ambient lighting, and simple sensor interfaces.
Industrial: Well-suited for motor control (e.g., small fans, pumps), sensor nodes, industrial automation interfaces, and power supply management.
Consumer Electronics: Used in appliances, power tools, personal care products, and interactive LED lighting systems.
Internet of Things (IoT): Serves as a capable brain for smart sensors and edge nodes, collecting and processing analog data before transmission.
The Microchip PIC16F15354T-I/ML stands out as a highly integrated and flexible 8-bit microcontroller. Its powerful combination of Core Independent Peripherals (CIPs), extensive analog capabilities, and ultra-low-power operation makes it an excellent solution for designers seeking to create efficient, reliable, and cost-optimized embedded systems for automotive, industrial, and consumer markets.
