Frequently Asked Questions

What is the maximum clock frequency and program memory size of PIC12C671-04I/P?

The PIC12C671-04I/P operates at a maximum clock frequency of 4 MHz and includes 1.75 kB of one-time programmable (OTP) program memory. This combination supports simple control algorithms, state machines, and sensor reading tasks with a 250 ns minimum instruction cycle time, making it suitable for tasks that do not require large code storage or high computational throughput.

Does PIC12C671-04I/P include an ADC, and what types of analog sensing applications can it address?

Yes, the PIC12C671-04I/P integrates an analog-to-digital converter (ADC), enabling direct reading of analog sensor outputs such as temperature sensors, potentiometers, and light-dependent resistors without requiring an external ADC chip. This reduces BOM cost and board complexity for 8-pin designs monitoring signals in the 0 V to VDD voltage range, typically 2.5 V to 5.5 V supply range for PIC12C devices.

When is PIC12C671-04I/P a better choice than a modern PIC12F series device for a legacy production run?

PIC12C671-04I/P is preferred in legacy products where existing OTP firmware images were originally compiled for the PIC12C671 architecture and re-qualification of a new device is too costly. It is also chosen for applications where the OTP (non-reprogrammable) nature of the memory is a security advantage, preventing field code extraction. For new designs, the PIC12F series offers flash reprogrammability at similar cost with a 4 MHz to 20 MHz clock range, but the PIC12C671 remains in production support for existing customers.
