Overview
The PIC16F1936-I/SO is an 8-bit microcontroller from Microchip's PIC16F family, designed for embedded control applications. It combines enhanced mid-range core architecture with nanoWatt XLP technology for ultra-low power consumption. The device is housed in a 28-pin SOIC package, offering a balance of performance and compact size. With 14KB of flash memory and 256B of EEPROM, it provides ample storage for firmware and data. The microcontroller includes a wide range of peripherals such as timers, ADCs, and communication interfaces (USART, SPI, I2C), making it versatile for various applications.
Structure and Working Principle
The PIC16F1936-I/SO features a Harvard architecture with separate program and data buses, enabling efficient instruction execution. Its enhanced core supports 49 instructions and a 16-level deep hardware stack. The device operates at up to 32MHz, delivering 8 MIPS performance. Key components include a 10-bit ADC, multiple PWM modules, and comparators for analog signal processing. The microcontroller's low-power modes (nanoWatt XLP) allow operation down to 20nA in sleep mode, making it suitable for battery-powered applications.
Key Features
The PIC16F1936-I/SO stands out for its ultra-low power consumption, achieving 20nA in sleep mode and 50μA/MHz in active mode. Its enhanced mid-range core offers improved performance over traditional 8-bit microcontrollers. The device includes robust peripherals such as a 10-bit ADC (up to 13 channels), multiple PWM modules, and hardware comparators. Communication interfaces (USART, SPI, I2C) facilitate easy integration with other components. The 14KB flash memory supports in-circuit serial programming (ICSP) for flexible firmware updates.
Application Areas
This microcontroller is widely used in embedded control systems across industries. Common applications include home automation (smart thermostats, lighting control), consumer electronics (appliances, toys), and industrial automation (sensors, motor control). Its low-power capabilities make it ideal for battery-operated devices like remote controls and portable medical instruments. The robust peripheral set also enables use in automotive systems (dashboard controls, small actuators) and IoT edge devices where reliability and efficiency are critical.
Maintenance and Precautions
Proper handling of the PIC16F1936-I/SO requires ESD protection during assembly and maintenance. Storage should be in moisture-sensitive packaging with humidity levels below 60% RH. Operating voltage must remain within the specified 2.0V to 5.5V range. PCB design should follow Microchip's layout guidelines, particularly for decoupling capacitors and crystal oscillator placement. Firmware should implement watchdog timers and brown-out reset protection for reliable operation. Regular firmware updates should be tested thoroughly before deployment.
B2B Procurement Guide
When procuring PIC16F1936-I/SO microcontrollers, verify authenticity through authorized distributors like Microchip Direct or franchised partners. Minimum order quantities typically start at 100 units, with bulk discounts available above 1,000 pieces. Lead times vary based on market demand but typically range from 4-12 weeks. Consider alternate part numbers (PIC16F1937, PIC16F1938) for expanded memory needs. Evaluate total cost of ownership including development tools (MPLAB IDE, PICkit programmers) and long-term availability forecasts.
