Key Features
- Compact 8-pin DIP form factor making it ideal for space-constrained or single-supply 2.5 V to 5.5 V analog sensing designs
- Integrated 4-channel 8-bit ADC enabling direct sensor interfacing without external analog-to-digital converter chips
- 10 MHz instruction throughput at 2.5 V to 5.5 V operating range covering a wide range of battery and regulated supply voltages
- Low pin-count PIC12 RISC architecture with 35 single-word instructions simplifying firmware development for simple control tasks
Applications
The PIC12C672-10I/P is suited for low-cost, high-volume consumer and industrial applications such as sensor signal conditioning, simple switch controllers, and appliance sequencing where an 8-pin MCU with ADC reduces external component count. Its 8-pin DIP package is convenient for prototype breadboarding and through-hole PCB assemblies in lighting timers, toy controllers, and small HVAC actuators. Legacy system maintenance and replacement parts for designs originally created in the late 1990s also represent a key use case.

Frequently Asked Questions
What ADC capability does PIC12C672-10I/P integrate and how many analog inputs does it support?
The PIC12C672-10I/P includes a 4-channel 8-bit successive-approximation ADC operating from 2.5 V to 5.5 V supply. With up to 4 analog input pins on the 8-pin DIP package, it can read multiple sensor outputs such as thermistors or light-dependent resistors directly without external analog circuitry, making it suitable for simple single-supply monitoring applications at up to 10 MHz.
For a legacy PCB still using PIC12C672-10I/P, what modern Microchip device provides a pin-compatible upgrade with Flash reprogrammability?
The PIC12F675 or PIC12F629 are direct 8-pin DIP replacements for the PIC12C672-10I/P. These Flash-based devices replace the OTP program memory with 1.75 KB of Flash, allow in-circuit reprogramming, and maintain the same 8-pin footprint and 2.0 V to 5.5 V operating range, making firmware updates practical without PCB layout changes.
What is the maximum clock frequency of PIC12C672-10I/P and how does it translate to instruction throughput?
The PIC12C672-10I/P operates at up to 10 MHz clock frequency. Since the PIC12 RISC architecture executes most instructions in a single cycle, this delivers 2.5 MIPS effective throughput. For simple sensor polling, PWM generation, or switch debounce loops, this speed is adequate when the device runs from a 5 V regulated supply or a 4 V battery pack.
What program memory type does PIC12C672-10I/P use and how does that affect production programming?
The PIC12C672-10I/P uses OTP (one-time programmable) memory with 2048 words of 14-bit instruction capacity. Because OTP cannot be erased, production programming requires a gang programmer and firmware must be finalized before programming. For prototyping phases, using a windowed EPROM variant or switching to a Flash-based PIC12F part is strongly recommended to avoid scrapping parts on firmware revisions.
