Microchip PIC16F1827-I/SO 8-Bit Microcontroller: Data Sheet and Design Guide
The PIC16F1827-I/SO from Microchip Technology represents a versatile and powerful 8-bit microcontroller within the enhanced mid-range PIC16F family. Housed in a compact 20-pin SOIC (Small Outline Integrated Circuit) package, this device is engineered for applications demanding high performance, low power consumption, and a rich set of integrated peripherals in a minimal footprint.
Core Architecture and Performance
At its heart lies an enhanced 8-bit RISC CPU core with a 32-level deep hardware stack and 49 instructions. Operating at a maximum frequency of 32 MHz, it achieves a performance of 8 MIPS. A key feature is its Nanowatt XLP (eXtreme Low Power) technology, making it exceptionally suited for battery-powered and energy-sensitive applications. The core is supported by 3.5 KB of Flash program memory, 128 Bytes of EEPROM, and 368 Bytes of SRAM.
Advanced and Core Independent Peripherals
The PIC16F1827 stands out with its sophisticated peripheral set, many of which are Core Independent Peripherals (CIPs), reducing CPU intervention and thus power consumption.
mTouch Capacitive Sensing Module: Allows for the implementation of robust touch sensing interfaces without external components.
Complementary Waveform Generator (CWG): Outputs complementary PWM signals, ideal for efficient motor control and power conversion systems.
Configurable Logic Cell (CLC): Integrates custom logic functions directly in hardware, enabling interface gluing and signal conditioning without code.
Enhanced Communication Interfaces: It includes EUSART (with LIN support), I2C, and SPI modules for flexible connectivity.
High-Performance PWM: Multiple PWM outputs with complementary modes are essential for precise control applications.
Development Ecosystem
Designing with the PIC16F1827 is streamlined by Microchip's extensive ecosystem. The MPLAB X Integrated Development Environment (IDE), coupled with the free XC8 compiler, provides a complete software solution. For hardware debugging and programming, tools like PICKit™ 4 or MPLAB ICD 4 are used. The microcontroller is also supported by MPLAB Code Configurator (MCC), a graphical tool that generates initialization code and simplifies peripheral setup, dramatically accelerating development time.
Key Application Areas
The combination of its peripheral set, low power, and small form factor makes the PIC16F1827-I/SO ideal for a wide range of applications, including:
Consumer Electronics (Touch Interfaces, Remote Controls)
Internet of Things (IoT) Sensor Nodes
Automotive (Body Electronics, Lighting Control)
Industrial (Low-Power Actuators, Sensor Modules)
Portable Medical and Healthcare Devices
