Frequently Asked Questions
Down to what supply voltage does PIC16LF873A-I/SS operate for battery-powered applications?
PIC16LF873A-I/SS operates from a supply as low as 2 V, which allows it to run from 2 series alkaline cells near end-of-life or a single lithium coin cell in depleted state. The full speed of 20 MHz is available across the 2 V to 5.5 V range, giving designers flexibility in power architecture without speed penalty at low supply voltages.
How many analog input channels and at what resolution does the PIC16LF873A-I/SS ADC operate?
The integrated ADC provides 5 analog input channels with 10-bit resolution, delivering 1024 discrete output codes per full-scale conversion. This configuration supports simultaneous multi-sensor systems measuring temperature via thermistor, light intensity via photodiode, and battery voltage simultaneously, all without any external ADC component.
For a compact embedded design, how small is the PIC16LF873A-I/SS footprint in 28-pin SSOP?
The 28-pin SSOP package measures approximately 10.2 mm × 5.3 mm with a fine 0.635 mm pin pitch. This compact SMT footprint is roughly 40% smaller than the equivalent 28-pin DIP package, enabling high-density PCB layouts where board space below 60 mm² for the MCU is a design constraint.
What serial interfaces on PIC16LF873A-I/SS allow connection to external memory and sensors?
The microcontroller integrates USART for asynchronous serial communication at standard baud rates up to 57600 bps, SPI for synchronous transfers at up to 5 MHz, and I2C in both master and slave modes supporting 400 kHz fast mode. These 3 independent interfaces allow simultaneous connection to a wireless UART module, an SPI display, and I2C sensors from a single MCU package.
When is PIC16LF873A-I/SS preferable to PIC16F873A for portable designs?
PIC16LF873A is the low-voltage variant specified to operate from 2 V to 5.5 V, while PIC16F873A requires a minimum of 4 V. For portable designs drawing from a lithium-ion cell that discharges below 3 V or a 2-cell AA battery pack with only 2.4 V at end-of-life, the LF variant continues functioning where the standard F version halts, extending battery service life by up to 30%.
