Frequently Asked Questions
Does the PIC16F819-I/SO include an ADC and how many channels does it have?
Yes, the PIC16F819-I/SO includes a built-in analog-to-digital converter (ADC). The ADC supports multiple input channels, allowing direct connection of analog sensors such as temperature sensors, potentiometers, or light-dependent resistors without requiring external ADC components, simplifying circuit design.
What is the maximum operating clock frequency of the PIC16F819-I/SO?
The PIC16F819-I/SO supports a maximum clock frequency of 20 MHz. With the PIC16 four-cycle instruction architecture, this translates to 5 MIPS peak instruction throughput, providing adequate performance for real-time control loops, sensor processing, and serial communication handling in embedded applications.
What serial communication interfaces are available on the PIC16F819-I/SO?
The PIC16F819-I/SO includes a USART for asynchronous and synchronous serial communication, plus an SSP (Synchronous Serial Port) module that supports both SPI and I2C protocols. These interfaces allow connection to a wide range of peripherals including EEPROMs, display drivers, sensors, and other microcontrollers.
What package does the PIC16F819-I/SO use?
The PIC16F819-I/SO is housed in an 18-pin SOIC (Small Outline Integrated Circuit) package, identified by Microchip package code SOIC-18. This surface-mount package has 1.27 mm pin pitch, making it easy to hand-solder during prototyping while remaining compatible with automated SMT assembly processes.
Is the PIC16F819-I/SO suitable for battery-powered applications?
Yes, the PIC16F819-I/SO is well suited for battery-powered designs. The PIC16 architecture includes multiple low-power sleep modes, and the device operates across a wide supply voltage range. When combined with its wake-on-interrupt capability, the microcontroller can achieve very low average current consumption in duty-cycled sensor applications.
