What are the key features of PIC16C71-04/SO?
- Integrated 4-channel ADC enables direct analog signal measurement without external conversion circuitry in 8-bit embedded designs
- Compact 18-pin SOIC package with 13 usable I/O lines provides a balance of pin density and solderability for cost-sensitive products
- PIC16 RISC architecture with single-cycle instruction execution at up to 4 MHz delivers predictable deterministic timing for real-time control tasks
What is PIC16C71-04/SO used for?
The PIC16C71-04/SO targets cost-sensitive embedded control applications such as appliance controllers, simple sensor interfaces, and low-power consumer devices where an 8-bit MCU with on-chip ADC is sufficient. Its 13 I/O pins and 4-channel ADC cover typical small-system needs including button scanning, LED driving, and analog sensor reading without external glue logic. The SOIC-18 package suits automated PCB assembly in moderate-volume production runs.

Frequently Asked Questions
What is the maximum clock frequency of the PIC16C71-04/SO and how does it affect instruction throughput?
The PIC16C71-04/SO runs at a maximum clock frequency of 4 MHz. Because the PIC16 core executes most instructions in a single 4-clock cycle, this translates to a peak instruction rate of 1 MIPS. This is adequate for simple sensor polling, timing loops, and low-speed communication at up to 9600 baud in many embedded control tasks.
How much program memory and RAM does the PIC16C71-04/SO provide for embedded firmware?
The PIC16C71-04/SO integrates 1.75 KB of OTP program memory and 36 bytes of general-purpose RAM. This is sufficient for compact firmware handling tasks like reading a 4-channel ADC, debouncing 4 to 8 input buttons, and driving up to 13 I/O lines in straightforward appliance or consumer control applications.
Does the PIC16C71-04/SO include an ADC, and how many channels does it support?
Yes, the PIC16C71-04/SO includes a built-in ADC with 4 input channels, allowing direct conversion of analog voltages without external ADC ICs. The ADC resolution is 8 bits, and with a 4 MHz clock and the PIC16C71 conversion timing, each conversion takes approximately 25 µs, making it suitable for low-bandwidth sensor applications such as temperature or position sensing.
