Frequently Asked Questions
What is the maximum clock frequency of the PIC16F84A-04/SO?
The PIC16F84A-04/SO operates at a maximum clock frequency of 4MHz, which provides sufficient processing speed for simple control tasks, I/O manipulation, and basic communication protocols like SPI and I2C bit-banging.
Does the PIC16F84A-04/SO have EEPROM memory?
Yes, the PIC16F84A-04/SO includes 64 bytes of on-chip EEPROM data memory that retains data after power loss, making it ideal for storing configuration settings, calibration values, and user data without external memory.
What package does the PIC16F84A-04/SO come in?
The PIC16F84A-04/SO is available in an 18-pin SOIC (Small Outline Integrated Circuit) surface-mount package, which is well suited for automated PCB assembly and compact designs compared to the through-hole DIP version.
Does the PIC16F84A-04/SO have an analog-to-digital converter?
No, the PIC16F84A-04/SO does not include an ADC. It is a purely digital microcontroller suited for applications requiring GPIO, timers, and EEPROM; analog sensing applications require an external ADC or a different PIC variant.
What development tools are available for the PIC16F84A-04/SO?
