Frequently Asked Questions - PIC16C67 Microchip
How do I program the PIC16C67?
You can program the PIC16C67 using a dedicated programmer like PICkit or ICD4. The device uses In-Circuit Serial Programming (ICSP) via PGD and PGC pins. Ensure correct voltage levels (5V typical).
What development tools support PIC16C67?
Supported tools include MPLAB X IDE, XC8 compiler, and programmers like PICkit 3/4, ICD 4, or third-party programmers. The device is part of the mid-range family.
Can I use the PIC16C67 with Arduino?
Not directly. The PIC16C67 is not Arduino-compatible. You would need an Arduino shield or separate programming hardware and adjust code using a PIC compiler.
What is the maximum clock frequency?
The maximum clock frequency is 20 MHz with an external oscillator. It can also operate with an internal 4 MHz oscillator (factory calibrated).
How many I/O pins does it have?
The PIC16C67 has 33 I/O pins in a 40-pin package. Some pins are multiplexed with special functions like ADC or comparator inputs.
Does it have built-in ADC?
Yes, it has an 8-channel, 8-bit analog-to-digital converter. The ADC can be configured with internal or external reference voltage.
What is the power consumption?
Typical power consumption is around 5 mA at 20 MHz with 3V supply. It supports multiple low-power modes: Sleep, Idle, and others, reducing current to microamps.
How to reset the PIC16C67?
The device has a dedicated MCLR pin (active low). Pulling this pin low resets the microcontroller. An external reset circuit is recommended for reliable operation.
What is the instruction set?
It uses a RISC instruction set with 35 instructions, all single-cycle except branches. Instructions are 14-bit wide.
Where can I find the full datasheet?
The full datasheet is available on Microchip's website (product page PIC16C67) or from the free manual on notice-facile.com in PDF format.
