Frequently Asked Questions
How many analog input channels does the PIC16LF72-I/SO provide, and what is the ADC resolution?
The PIC16LF72-I/SO integrates a 5-channel, 8-bit successive-approximation ADC, allowing it to directly digitize up to 5 independent analog signals without external converter ICs. At 5 V supply, the LSB resolution is approximately 19.6 mV, suitable for temperature sensor and resistive divider readings.
At what minimum supply voltage can PIC16LF72-I/SO operate, and how does this affect clock speed?
PIC16LF72-I/SO operates from as low as 2.0 V, which is the key advantage of the LF (low-voltage) variant over the standard PIC16F72 that requires 4.5 V. At 2 V the maximum clock frequency is 4 MHz, yielding 1 MIPS; full 10 MHz operation is available at supply voltages above 4.5 V.
Which communication interfaces are available on PIC16LF72-I/SO for connecting sensors and host processors?
The device includes a hardware-enhanced USART for asynchronous serial communication up to 625 kbaud at 10 MHz clock, plus a hardware SSP module supporting both SPI mode up to 5 Mbps and I2C up to 400 kHz. These interfaces allow connection to displays, EEPROMs, accelerometers, and host microprocessors with minimal software overhead.
Is PIC16LF72-I/SO a drop-in replacement for PIC16F72, and what differs between the two?
PIC16LF72-I/SO is pin-compatible with PIC16F72 in the same 28-pin SOIC footprint, but operates from 2.0 V to 5.5 V versus the 4.5 V to 5.5 V range of the standard F72 variant. Firmware compiled for PIC16F72 runs unchanged on PIC16LF72, making it a straightforward drop-in replacement when a wider voltage range or lower power consumption is needed.
How many digital I/O pins are available on PIC16LF72-I/SO, and how are they organized?
The PIC16LF72-I/SO provides 22 digital I/O pins organized across three 8-bit ports (PORTA, PORTB, PORTC), with each pin individually configurable as input or output via TRIS registers. Maximum sink and source current is 25 mA per pin and 200 mA total per port, supporting direct LED drive without external transistors.
