Key Features
- Low-voltage 8-bit PIC16 core verified at 4 MHz from a 2.2 V minimum supply, enabling direct battery operation
- 3.5 KB flash and 128 bytes SRAM with an integrated 5-channel 10-bit ADC for sensor data acquisition
- 28-pin SSOP surface-mount package with SPI, I2C, USART, and up to 22 GPIO lines for compact PCB designs
Applications
PIC16LF872-I/SS is well suited for portable sensor nodes, low-power industrial controls, and battery-operated consumer electronics that demand reliable operation at 2.2 V to 5.5 V. Its SSOP-28 footprint enables high-density PCB layouts, and the integrated USART and SPI peripherals simplify connection to wireless modules, displays, and memory chips. The 10-bit ADC with 5 input channels supports direct measurement of temperature, pressure, or light intensity signals.

Frequently Asked Questions
Down to what supply voltage can PIC16LF872-I/SS reliably execute code, and at what clock frequency?
PIC16LF872-I/SS operates reliably down to 2.2 V minimum supply voltage while running at 4 MHz, making it compatible with two-cell NiMH or a partially discharged 3 V lithium coin cell. At full 5 V supply, clock frequency rises to 20 MHz for more demanding processing tasks.
For a compact industrial sensor transmitter design, how does the SSOP-28 package of PIC16LF872-I/SS compare to a DIP alternative in board area?
The SSOP-28 package measures approximately 10 mm x 5.3 mm with 0.65 mm pitch, occupying around 53 mm² of PCB footprint, while an equivalent 28-pin DIP requires roughly 400 mm². This 7x footprint reduction makes PIC16LF872-I/SS the preferred choice for miniaturized sensor transmitters and wearable device designs.
How many ADC input channels does PIC16LF872-I/SS provide, and what resolution do measurements achieve?
PIC16LF872-I/SS integrates a 5-channel, 10-bit successive-approximation ADC delivering 1024 quantization steps across the supply reference span. With Vref set to 5 V, each LSB represents approximately 4.9 mV, providing sufficient resolution for NTC thermistor, potentiometer, or pressure sensor readings without requiring an external ADC.
