Applications
The PIC16LF874A-I/PT is widely used in battery-operated industrial sensors, data loggers, and home automation controllers where its 2V minimum supply and 20 MHz maximum clock provide a flexible power-performance tradeoff. The combination of 10-bit ADC, EEPROM, and serial communication peripherals suits temperature transmitters, pressure sensors, and smart metering devices that require autonomous data acquisition and RS-485 reporting. The 44-pin TQFP package is common in mid-complexity PCB designs where SMD assembly is available and higher I/O count than DIP alternatives is needed.

Frequently Asked Questions
Can the PIC16LF874A-I/PT run from a 3.3V supply, and what clock frequency does it support at that voltage?
Yes, the PIC16LF874A is rated for operation from 2V to 5.5V, so a 3.3V supply is within spec. At 3.3V the device runs at its full 20 MHz maximum clock frequency, delivering up to 5 MIPS of instruction throughput for real-time control tasks.
What analog signal-chain capability does the PIC16LF874A provide for sensor measurement applications?
The PIC16LF874A integrates a 10-bit successive-approximation ADC with 8 multiplexed input channels, covering standard voltage measurements from 0V to VDD. This 10-bit resolution (1 in 1024 codes) suits 4–20 mA industrial sensor inputs, NTC thermistor bridges, and resistive gas sensors without external ADC devices.
How does the 128-byte on-chip EEPROM of the PIC16LF874A benefit embedded applications requiring non-volatile storage?
The 128-byte EEPROM on the PIC16LF874A retains calibration coefficients, configuration flags, and event counters across power cycles without external serial EEPROM ICs. A typical 8-byte floating-point calibration record leaves 120 bytes free for additional parameters, reducing BOM cost and PCB area in sensor transmitter designs.
For a surface-mount industrial sensor PCB, what does the PIC16LF874A-I/PT 44-pin TQFP package offer compared to a DIP variant?
The 44-pin TQFP measures 10 mm x 10 mm with 0.8 mm pin pitch, occupying roughly 4x less PCB area than an equivalent 40-pin DIP package. It provides 33 I/O lines versus 22 on a 28-pin DIP, enabling additional sensor channels, status LEDs, and communication interfaces within the same chip.
