Applications
The PIC16LF877A-I/L targets low-power embedded control applications including battery-operated industrial sensors, smart metering devices, and HVAC controllers that require a reliable 8-bit MCU with multi-channel analog input and serial communication. Its 2 V minimum supply and wide 2 V to 5.5 V operating range make it a practical choice for solar-energy-harvesting data loggers and agricultural sensor nodes operating from small lithium or alkaline batteries. The 44-pin PLCC footprint and rich peripheral set also suit retrofit industrial control panels and legacy equipment upgrades where through-hole or socketed assembly is preferred.

Frequently Asked Questions
What is the operating voltage range and maximum clock frequency of the PIC16LF877A-I/L?
The PIC16LF877A-I/L operates from 2 V to 5.5 V supply voltage and can run at up to 20 MHz clock frequency at full voltage. At the 2 V minimum supply, the device operates at reduced frequencies, allowing designers to balance processing speed against power consumption in battery-powered applications requiring months to years of field operation.
How many ADC channels and what resolution does the PIC16LF877A-I/L provide for sensor acquisition?
The PIC16LF877A-I/L integrates an 8-channel, 10-bit ADC, providing 1024 quantization levels per channel and approximately 4.9 mV resolution at a 5 V reference. This makes it capable of reading multiple analog sensors simultaneously — such as temperature, humidity, current, and pressure transducers — without external ADC ICs, reducing BOM cost in multi-sensor industrial and agricultural monitoring designs.
Which communication peripherals are built into PIC16LF877A-I/L and what bus types do they support?
The PIC16LF877A-I/L includes a USART for RS-232 and RS-485 serial links, an SPI master/slave module supporting up to 10 Mbps for sensor and memory bus use, and an I2C module for connecting EEPROMs, RTCs, and LCD drivers at up to 400 kHz. Two CCP (Capture/Compare/PWM) modules add hardware PWM for motor speed control and timer capture for frequency measurement, covering most embedded connectivity requirements in one package.
When is the 44-pin PLCC package of PIC16LF877A-I/L preferred over a QFP or DIP alternative for industrial equipment?
The 44-pin PLCC package is preferred in industrial equipment where socketed assembly and field replacement are needed, since the square 17.78 mm x 17.78 mm LCC carrier can be inserted or removed without soldering tools. For retrofit control board upgrades and legacy manufacturing equipment with existing PLCC sockets, the PIC16LF877A-I/L fits directly into 44-pin PLCC sockets without PCB redesign, reducing re-qualification costs and shortening time to market for replacement designs.
