Key Features
- 4 MHz OTP PIC16C core with 3.5 KB (2K x 14-bit) program memory provides a proven, fixed-code solution for high-volume cost-sensitive embedded control applications
- Integrated multi-channel ADC enables direct analogue sensor acquisition without external conversion components, reducing BOM count and PCB area
- 28-pin SPDIP through-hole package supports hand-assembly, socketed prototyping, and field serviceability in industrial and legacy product maintenance scenarios
Applications
The PIC16C72-04/SP is suited for simple embedded control applications such as household appliance controllers, HVAC thermostat logic, and motor speed regulators where a low-cost 8-bit OTP MCU with integrated ADC meets all functional requirements. Its 28-pin SPDIP package makes it ideal for through-hole prototype boards and legacy product repairs where SMD rework is not practical. Running at 4 MHz from a standard 5 V supply, it covers a broad range of low-speed sensing, switching, and timing tasks in industrial and consumer electronics.

Frequently Asked Questions
How does the OTP program memory of the PIC16C72-04/SP affect production programming compared to Flash-based MCUs?
The PIC16C72-04/SP uses one-time programmable (OTP) memory, meaning firmware is written once and cannot be erased or updated. This lowers per-unit cost in high-volume production where the code is finalised, but requires a separate development MCU such as a windowed EPROM variant or a PIC16F device for firmware iteration before committing to OTP programming.
How many ADC channels does the PIC16C72-04/SP offer, and what resolution do they provide?
The PIC16C72-04/SP integrates a 5-channel 8-bit ADC, allowing direct connection of up to 5 analogue sensors such as thermistors, potentiometers, or pressure transducers. The 8-bit resolution yields 256 quantisation levels over the reference voltage range, suitable for low-resolution measurements in thermostat and motor control applications.
Which supply voltage range does the PIC16C72-04/SP support, and can it interface directly with 3.3 V logic?
The PIC16C72-04/SP operates from a 4.5 V to 5.5 V supply rail centred on 5 V. Its logic high input threshold is typically above 2 V, so direct connection to 3.3 V logic is marginal and a level-shifter or pull-up resistor to 5 V is recommended to ensure reliable logic recognition in mixed-voltage systems.
For a legacy industrial control board requiring a pin-compatible PIC16C72-04/SP replacement, which Flash-based alternative offers the same 28-SPDIP footprint?
The PIC16F72 or PIC16F873A provides a pin-compatible 28-SPDIP footprint with the same 4 MHz operation and ADC capability, but replaces the OTP memory with re-programmable Flash up to 7 KB. Migrating requires only a firmware rebuild targeting the new device; no hardware changes are needed because the package, pinout, and peripheral map are closely aligned.
