What are the key features of PIC16LC71A-04I/P?
- 8-bit PIC core with 4 MHz maximum clock frequency and 1.75 KB (1K x 14) OTP program memory for cost-sensitive embedded control
- Integrated analog-to-digital converter (ADC) eliminates the need for external signal conditioning in sensor-based designs
- 18-PDIP through-hole package enables breadboard prototyping and easy hand-soldering for low-volume or legacy-compatible production runs
What is PIC16LC71A-04I/P used for?
The PIC16LC71A-04I/P is well suited for low-power sensor acquisition, simple control loops, and battery-operated consumer devices that benefit from its integrated ADC and low-voltage operation. Its 8-bit architecture and 4 MHz clock make it a cost-effective solution for industrial timers, motor control, and basic user-interface logic in appliances and handheld equipment. The 18-PDIP package simplifies prototyping and supports DIP socket-based field-replacement in legacy industrial instrumentation.

Frequently Asked Questions
What is the maximum clock speed and program memory size of the PIC16LC71A-04I/P, and how does that shape its application scope?
The PIC16LC71A-04I/P runs at up to 4 MHz and holds 1.75 KB (1,024 x 14-bit words) of OTP program memory. This combination is sufficient for simple control tasks such as keypad scanning, relay sequencing, or 4-channel ADC data logging, but limits the device to applications where the firmware fits within approximately 1,000 instructions.
For a low-power sensor node running from a 3 V coin cell, how does the PIC16LC71A-04I/P's low-voltage design help?
The PIC16LC71A (LC variant) is designed for low-voltage operation, typically from 2 V to 5.5 V, making it directly compatible with a 3 V CR2032 coin cell without a boost regulator. At 4 MHz with the internal ADC active, supply current is typically under 2 mA, enabling a coin-cell-powered sensor node to operate for months between battery changes.
When is the OTP (one-time programmable) PIC16LC71A-04I/P preferable to a flash-based PIC microcontroller for production procurement?
OTP devices like the PIC16LC71A-04I/P are preferable when firmware is fully validated and production volumes exceed 10,000 units, because OTP parts typically cost 20% to 40% less per unit than equivalent flash-based MCUs. They also offer superior data retention beyond 40 years at 85°C, which matters for long-life industrial equipment where re-programming in the field is not required.
