Key Features
- Low-voltage operation from 2.0 V to 5.5 V enabling direct battery-powered and 3.3 V system designs at up to 20 MHz
- 3.5 kB Flash program memory with 64-byte on-chip EEPROM for non-volatile parameter storage without external memory
- 8-channel 10-bit ADC provides multichannel analog sensing for sensors and signal conditioning in a single 28-pin SOIC device
- In-circuit serial programming (ICSP) support simplifies field firmware updates and production programming
Applications
The PIC16LF870-I/SO serves low-power embedded control applications such as battery-operated remote controls, HVAC sensors, and small home appliance controllers where its 2.0 V to 5.5 V range and on-chip EEPROM reduce external component count. Its 8-channel 10-bit ADC and 20 MHz maximum clock make it suitable for multi-sensor data loggers, motor soft-start controllers, and industrial panel interfaces in space-constrained 28-pin SOIC designs.

Frequently Asked Questions
What is the minimum operating voltage of PIC16LF870-I/SO and how does it enable battery-powered designs?
The PIC16LF870-I/SO operates from as low as 2.0 V up to 5.5 V, making it compatible with 2-cell alkaline or single-cell Li-ion battery supplies. At 2.0 V the MCU can run at reduced clock speeds, enabling long-life sensor nodes that continue functioning as the battery discharges well below the 3.3 V threshold required by non-LF variants.
How many ADC channels does PIC16LF870-I/SO provide and what resolution do they offer?
PIC16LF870-I/SO includes 8 analog input channels connected to a 10-bit successive-approximation ADC, delivering 1024 discrete steps across the reference voltage span. This resolution is adequate for measuring temperature sensors, potentiometers, and low-bandwidth analog signals in industrial and consumer applications without external ADC ICs.
For a legacy PIC16C870 replacement design, is PIC16LF870-I/SO pin-compatible?
Yes, PIC16LF870-I/SO is the Flash-based, low-voltage successor to the PIC16C870 and is pin-compatible in the same 28-pin SOIC footprint. The LF suffix indicates low-voltage operation down to 2.0 V versus the standard 4.5 V minimum, allowing direct board-level substitution while gaining the benefit of reprogrammable Flash and 64-byte EEPROM.
What non-volatile storage does PIC16LF870-I/SO offer for storing calibration data?
PIC16LF870-I/SO provides 64 bytes of on-chip EEPROM data memory in addition to its 3.5 kB Flash program memory. This EEPROM retains calibration coefficients, configuration flags, and counters across power cycles without requiring an external EEPROM IC, reducing BOM cost and simplifying firmware in sensor calibration and appliance control designs.
