Frequently Asked Questions
How many analog input channels does PIC16C72A-20/SP provide, and what is their resolution?
PIC16C72A-20/SP integrates a 5-channel, 8-bit successive-approximation ADC. Each channel can resolve input voltages from VSS to VDD (2.0V to 5.5V) into 256 discrete steps, giving a voltage resolution of approximately 19.5mV per LSB at 5V. This is sufficient for temperature sensors, potentiometers, and light-intensity measurements in 8-bit embedded control designs.
What program memory type does PIC16C72A-20/SP use, and how does that affect production programming in high-volume manufacturing?
PIC16C72A-20/SP uses OTP (One-Time Programmable) memory with 2KB capacity. OTP devices must be programmed before assembly since the code cannot be erased or updated in the field. For high-volume production runs this reduces per-unit cost compared to Flash variants, but requires pre-programming in batches using a gang programmer set to the 20 MHz configuration fuses and a 5V VDD programming supply.
Is PIC16C72A-20/SP still in production, and what modern Microchip device offers a pin-compatible upgrade path?
PIC16C72A-20/SP was introduced in 1990 and has a low YTEOL (years-to-end-of-life) rating, indicating limited production life remaining. A compatible Flash-based upgrade is the PIC16F72 in the same 28-pin DIP footprint, which adds 4KB of re-programmable Flash, 128 bytes of EEPROM, and retains the 5-channel 8-bit ADC and 20 MHz maximum clock, simplifying PCB-level migration.
For a 5V industrial sensor board using PIC16C72A-20/SP at 20 MHz, what are the key power consumption characteristics?
At 5V and 20 MHz, PIC16C72A-20/SP draws approximately 5–8mA in active operation. In Sleep mode with the watchdog timer active, current drops to under 50µA at 5V, making it suitable for power-cycled industrial sensors that wake periodically to sample the 5-channel ADC and transmit via the on-chip UART at up to 625 kbaud.
