Microchip PIC16LF72-I/SO 8-Bit Microcontroller Data Sheet and Technical Specifications
The Microchip PIC16LF72-I/SO is a high-performance, low-power 8-bit microcontroller built on an enhanced RISC architecture. It belongs to Microchip’s popular PIC16F family, offering a balance of processing capability, power efficiency, and peripheral integration ideal for a wide range of embedded control applications, including consumer electronics, sensor interfaces, and low-power systems.
Core Architecture and Performance
At the heart of the PIC16LF72-I/SO is an enhanced CMOS FLASH-based 8-bit CPU. It features a 35-word single-cycle instruction set, enabling most instructions to execute in a single clock cycle. This RISC architecture delivers a high throughput at clock speeds up to 20 MHz, achieving a performance level of up to 5 MIPS (Million Instructions Per Second). This efficiency makes it suitable for real-time control tasks.
Memory Configuration
This microcontroller is equipped with:
3.5 KB (4096 words) of FLASH Program Memory: This memory is reprogrammable, allowing for significant design flexibility and firmware updates.
128 Bytes of RAM (File Registers): Provides data storage for program variables during operation.
128 Bytes of EEPROM Data Memory: This non-volatile memory is ideal for storing critical data that must be retained even when power is removed, such as calibration constants or user settings.
Low-Power Characteristics
A defining feature of the 'LF' variant is its low-power operation. The device is designed for applications requiring extended battery life. It supports a wide operating voltage range from 2.0V to 5.5V, enabling it to function efficiently even as battery voltage decays. Furthermore, it features multiple power-saving modes, including SLEEP mode, which reduces power consumption to nanoampere levels.
Integrated Peripherals
The PIC16LF72-I/SO integrates a robust set of peripherals that reduce the need for external components, simplifying design and lowering system cost:
5-Channel 8-Bit Analog-to-Digital Converter (ADC): Allows the microcontroller to interface with analog sensors and signals.
Three Timers (TMR0, TMR1, TMR2): Provide necessary timing and counting functions for event management and PWM generation.
2 Capture/Compare/PWM (CCP) Modules: Offer capabilities for capturing external events, comparing signals, and generating Pulse-Width Modulated (PWM) outputs for motor control or power regulation.
Universal Synchronous Asynchronous Receiver Transmitter (USART): Facilitates serial communication (RS-232, RS-485) with PCs, peripherals, or other microcontrollers.
Parallel Slave Port (PSP): Allows for 8-bit parallel communication with a microprocessor bus.
Packaging and Temperature Range
The device is offered in the 28-pin SOIC (SO) package, which is suitable for surface-mount technology (SMT) on PCBs. The '-I' suffix denotes an industrial temperature range of -40°C to +85°C, making it robust enough for demanding environments outside of standard commercial applications.
Development Support
Microchip provides a complete ecosystem for development, including the MPLAB X Integrated Development Environment (IDE) and hardware tools like the PICkit™ programmer. This extensive support ensures a streamlined path from prototyping to production.
The Microchip PIC16LF72-I/SO is a versatile and power-efficient 8-bit microcontroller. Its combination of ample FLASH memory, integrated EEPROM, a rich set of peripherals (ADC, CCP, USART), and exceptional low-power capabilities makes it an outstanding choice for designers developing cost-sensitive, battery-powered, or space-constrained embedded systems requiring reliable performance in industrial environments.
