Frequently Asked Questions
What is the maximum clock frequency of the PIC16F874-04/PT?
The PIC16F874-04/PT has a maximum clock frequency of 4MHz, as indicated by the '04' in the part number. This makes it suitable for cost-sensitive embedded control applications where moderate processing speed is sufficient, such as sensor data acquisition, simple state machine control, and low-speed communication tasks in industrial and consumer products.
Does the PIC16F874-04/PT have an ADC?
Yes, the PIC16F874-04/PT includes an integrated analog-to-digital converter (ADC). This allows the microcontroller to directly sample analog signals from sensors, transducers, and other analog sources. The integrated ADC eliminates the need for an external converter chip, reducing component count, board area, and overall system cost in data acquisition and control applications.
What package does the PIC16F874-04/PT use?
The PIC16F874-04/PT is housed in a 44-pin TQFP (Thin Quad Flat Package) surface-mount package. This package provides a compact footprint with fine-pitch leads on all four sides, enabling access to up to 33 I/O pins in a relatively small PCB area. It is well-supported by standard SMT assembly equipment and is Pb-free.
What CPU family does the PIC16F874-04/PT belong to?
The PIC16F874-04/PT belongs to Microchip's PIC16 microcontroller family, an 8-bit RISC architecture first introduced in the 1990s. The PIC16 family has an extensive ecosystem including MPLAB IDE, XC8 compiler, and thousands of application notes and code examples, making it one of the most widely used 8-bit microcontroller platforms in embedded systems development.
When was the PIC16F874-04/PT introduced and is it still in production?
The PIC16F874-04/PT was introduced on December 1, 1998, making it a mature and well-established product with extensive field usage history. Its YTEOL (years to end of life) value indicates it is in the later stages of its product lifecycle. Designers starting new projects should evaluate current-generation PIC16F88x or PIC16F1xxx family devices for better feature integration, while existing designs can continue using available stock.
