Microchip PIC16F1828T-I/ML 8-Bit Microcontroller Datasheet and Application Overview
The PIC16F1828T-I/ML from Microchip Technology represents a versatile and powerful 8-bit microcontroller, engineered to deliver high performance and flexibility for a wide range of embedded applications. Housed in a compact 28-pin QFN (ML) package, this device is designed for space-constrained and power-sensitive designs, making it a popular choice in consumer electronics, industrial automation, automotive systems, and IoT devices.
Core Architecture and Key Features
At the heart of the PIC16F1828T-I/ML lies an enhanced mid-range core with a 16-level deep hardware stack and a 49-instruction set, enabling efficient and deterministic operation. It operates at a maximum frequency of 32 MHz, providing a solid balance between processing power and energy consumption. A standout feature is its nanoWatt XLP (eXtreme Low Power) technology, which is critical for battery-powered applications, allowing the device to operate with currents as low as 20 nA in Sleep mode.
The microcontroller is equipped with 14 KB of Flash program memory and 1 KB of RAM, offering ample space for moderately complex firmware. It also features 256 bytes of EEPROM for non-volatile data storage, which is essential for storing configuration parameters and user data without power.
Advanced Peripherals for Enhanced Functionality
The PIC16F1828T-I/ML integrates a rich set of peripherals that reduce the need for external components, simplifying design and lowering the overall system cost.
mTouch Capacitive Sensing Module: This allows for the implementation of robust touch sensing interfaces (buttons, sliders, proximity) without external dedicated ICs.
Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART): Supports both LIN and DMX protocols, ideal for serial communication in automotive and lighting control systems.
Two Configurable Logic Cells (CLC): These allow for the creation of custom combinatorial and sequential logic functions directly in hardware, offloading simple tasks from the CPU and enabling faster response to external events.
Complementary Waveform Generator (CWG): This peripheral is particularly useful for precise motor control and power conversion applications, generating complementary PWM signals with dead-band control.
10-bit Analog-to-Digital Converter (ADC): With up to 12 channels, it provides accurate analog signal acquisition for sensor data reading.
Development and Programming Ecosystem
Development is supported by Microchip’s comprehensive MPLAB X Integrated Development Environment (IDE) and the XC8 compiler. The microcontroller is also compatible with the PICKit™ 4 and MPLAB Snap programmers/debuggers, offering a seamless path from prototyping to production. Its In-Circuit Serial Programming (ICSP)
capability allows for easy firmware updates even after the product is assembled.
Typical Application Overview
A typical application for the PIC16F1828T-I/ML could be in a smart home thermostat. In this scenario:
The mTouch module would drive the capacitive touch interface for user input.
Internal temperature sensors or external ones via the ADC would monitor ambient conditions.
The EUSART could facilitate communication with a Wi-Fi module for cloud connectivity.
The CWG could be used to control the fan motor or a damper actuator efficiently.
The ultra-low power consumption in Sleep mode would ensure long battery life if the unit is wireless.
