Frequently Asked Questions - PIC12C671 Microchip
What is the PIC12C671?
The PIC12C671 is an 8-bit microcontroller from Microchip Technology, featuring 1.75 KB of OTP EPROM program memory, 128 bytes of RAM, and an analog comparator.
How do I program the PIC12C671?
Programming is done via In-Circuit Serial Programming (ICSP) using a compatible programmer such as PICkit or ICD. The device is OTP (one-time programmable), so ensure code is final before programming.
What is the operating voltage range?
The PIC12C671 operates from 3.0V to 5.5V. Typical supply current is less than 2 mA at 5V and 4 MHz.
How many I/O pins does it have?
The device has 6 I/O pins (GP0-GP5), but two are shared with the analog comparator inputs. The pins are multiplexed with other functions.
Can I use the PIC12C671 for analog applications?
Yes, it includes an analog comparator with an internal voltage reference (0.6V or 1.2V). It can compare external analog signals and trigger interrupts.
What is the maximum clock speed?
The maximum external clock speed is 10 MHz. The internal oscillator is not available; an external clock or resonator is required.
Is the PIC12C671 still in production?
No, the PIC12C671 is an obsolete OTP device. It has been replaced by the PIC12F671 and other flash-based microcontrollers.
What development tools support this device?
Microchip's MPLAB X IDE and older MPLAB IDE support the PIC12C671. Compilers include XC8 (C) and MPASM (assembly).
How do I handle ESD precautions?
Use an anti-static wrist strap and work on a grounded mat. Store the device in anti-static packaging. Avoid touching pins directly.
Can I replace the PIC12C671 with a PIC12F671?
Yes, the PIC12F671 is a drop-in replacement with flash memory, allowing reprogramming. Check datasheet for minor differences like power consumption.
