Frequently Asked Questions
What is the maximum clock frequency of the PIC16F877-20/PT?
The PIC16F877-20/PT supports a maximum clock frequency of 20 MHz, delivering up to 5 MIPS throughput. It can be driven by an external crystal, resonator, or internal RC oscillator, giving designers flexibility in balancing speed and power consumption.
How many ADC channels does the PIC16F877-20/PT have?
The PIC16F877-20/PT includes an 8-channel, 10-bit successive-approximation ADC. This allows direct connection of up to 8 analog sensors or signals, eliminating the need for an external ADC and simplifying board-level design in measurement and control applications.
What package does the PIC16F877-20/PT use and what does the suffix mean?
The suffix '20/PT' indicates the 20 MHz speed grade in a 44-pin TQFP (Thin Quad Flat Pack) plastic surface-mount package. The TQFP-44 outline measures 10 mm x 10 mm with 0.8 mm pin pitch, suitable for automated pick-and-place assembly.
Is the PIC16F877-20/PT RoHS compliant and lead-free?
Yes, the PIC16F877-20/PT carries a Pb-free (lead-free) code of 'Yes', confirming compliance with RoHS directives. It uses a green, halogen-free mold compound and a tin-silver-copper solder finish, making it compatible with lead-free soldering processes used in modern electronics manufacturing.
What are common alternatives or drop-in replacements for the PIC16F877-20/PT?
Common functional alternatives include the PIC16F877A-20/PT, which is the enhanced version with improved oscillator and memory specifications, as well as the PIC18F4520 for applications requiring more program memory or USB. For 20 MHz operation in the same TQFP-44 footprint, the PIC16F877A is the most direct replacement.
