What is PIC16C72A-04/SS used for?
The PIC16C72A-04/SS is used in legacy industrial control systems, appliance timers, and sensor interface circuits where an 8-bit EPROM-based microcontroller with built-in ADC provides a proven, cost-effective solution at 4 MHz clock speed. Its EPROM architecture makes it suitable for prototype development where firmware is expected to be revised multiple times before final production using OTP or flash variants. The 28-pin SSOP package fits standard SMT assembly equipment, supporting both new board designs and direct replacement of aging PIC16C72 devices in fielded equipment.

Frequently Asked Questions
What clock speed and memory type does the PIC16C72A-04/SS feature and how does EPROM differ from flash?
The PIC16C72A-04/SS runs at up to 4 MHz and uses EPROM program memory, which can be erased with UV light and reprogrammed multiple times during development, unlike OTP memory that programs only once. This makes it useful for prototype iterations at 4 MHz before committing to a one-time programmable production variant, while the built-in ADC avoids the need for an external analog-to-digital converter chip.
How many ADC channels does the PIC16C72A-04/SS provide and what input voltage range do they support?
The PIC16C72A-04/SS integrates up to 5 analog input channels through its ADC peripheral, capable of measuring signals referenced to VSS up to VDD, which is typically 5 V. This on-chip ADC eliminates the need for a separate SPI or I2C ADC IC in low-complexity sensor interface boards such as temperature monitoring, light sensing, or battery voltage measurement applications running at 4 MHz.
Which industrial or maintenance scenarios still justify sourcing the PIC16C72A-04/SS today?
The PIC16C72A-04/SS remains relevant for repairing or extending the life of legacy industrial equipment built before 2000 that relied on the PIC16C72 family at 4 MHz, where replacing the entire controller board is far more expensive than sourcing a pin-compatible replacement. Its 28-pin SSOP footprint and identical instruction set to the original PIC16C72 allow direct board substitution without firmware or layout changes in PLC modules, HVAC controllers, and instrument front panels.
How does the 28-pin SSOP package of the PIC16C72A-04/SS compare to DIP alternatives for PCB integration?
The 28-pin SSOP package occupies roughly 40% less PCB area than a 28-pin DIP footprint, making it preferable in compact SMT designs where board space is constrained. Although hand-soldering SSOP at 0.635 mm pitch requires care, standard automated pick-and-place equipment handles it at production volumes, giving the PIC16C72A-04/SS a practical advantage over DIP versions in modern manufacturing environments.
