Microchip PIC16F15356-I/ML 8-Bit Microcontroller Datasheet and Application Overview
The Microchip PIC16F15356-I/ML is a versatile 8-bit microcontroller (MCU) from Microchip Technology’s enhanced mid-range PIC16F family. Housed in a compact 28-pin QFN (5x5mm) ML package, this MCU is engineered for a wide array of embedded control applications, balancing processing capability, power efficiency, and peripheral integration.
Core Architecture and Performance
At its heart, the PIC16F15356 employs an enhanced 8-bit RISC CPU core with a 49-instruction set, operating at speeds up to 32 MHz. This allows for a maximum performance of 8 MIPS. A key architectural advantage is its Independent Peripheral Interrupt (IPI) capability, which allows critical peripherals to communicate directly with each other and trigger actions without CPU intervention. This significantly reduces latency and power consumption in event-driven applications.
Memory Configuration
The device features 28 KB of self-read/write Flash program memory and 2 KB of RAM. This substantial memory size for an 8-bit MCU supports more complex firmware and data handling. The Flash memory offers 1,000 erase/write cycle endurance and data retention of 40 years, ensuring long-term reliability.
Integrated Peripherals and Features
The peripheral set of the PIC16F15356 is a standout feature, making it a highly integrated solution:
Analog: It includes a 10-bit Analog-to-Digital Converter (ADC) with up to 35 channels and a computation feature for automated signal analysis, a 5-bit Digital-to-Analog Converter (DAC), and two comparators.
Timing and Control: The MCU is equipped with multiple timers (e.g., 8-bit, 16-bit), a Windowed Watchdog Timer (WWDT), and a Hardware Limit Timer (HLT) for enhanced safety in critical applications.
Communication: It supports a range of serial communication protocols, including I2C, SPI, and EUSART (LIN capable), facilitating easy connection to sensors, displays, and other system components.
Core Independent Peripherals (CIPs): These are a hallmark of modern PIC MCUs. The device includes Complementary Waveform Generator (CWG), Capture/Compare/PWM (CCP), and Numerically Controlled Oscillators (NCO), which operate autonomously, offloading tasks from the CPU.
Development Support
Designing with the PIC16F15356 is supported by Microchip’s comprehensive MPLAB X Integrated Development Environment (IDE) and the MPLAB Code Configurator (MCC). MCC is a particularly powerful plugin that generates initialization code and drivers through a graphical interface, dramatically accelerating development time.
Application Overview
The robust integration of analog, control, and communication peripherals makes the PIC16F15356-I/ML ideal for a diverse range of applications, including:
Automotive Electronics: Body control modules, sensors, and lighting systems.
Industrial Control: Motor control, power converters, and factory automation.
Consumer Electronics: Appliances, power tools, and user interface controls.
Internet of Things (IoT): Smart sensor nodes and edge devices.
The Microchip PIC16F15356-I/ML stands out as a powerful and highly integrated 8-bit microcontroller. Its blend of substantial memory, a rich set of Core Independent Peripherals (CIPs), and robust analog capabilities provides a flexible and efficient solution for complex embedded designs. The autonomous operation of its peripherals reduces CPU overhead, enabling smarter and more power-efficient systems across automotive, industrial, and consumer markets.
