What are the key features of PIC16L(F)18875?
- Low-voltage PIC16 8-bit core operating down to 1.8 V enables direct integration with low-power sensors and sub-3 V battery-powered designs
- 44-pin TQFP package (10 mm × 10 mm) provides ample I/O for interfacing multiple peripherals such as displays, motor drivers, and communication modules
- Rich integrated peripheral set including ADC, PWM, UART, SPI, and I2C reduces external component count in embedded control designs
What is PIC16L(F)18875 used for?
The PIC16LF18875 suits cost-sensitive embedded control applications such as home appliance control panels, HVAC fan controllers, and industrial sensor nodes that benefit from a 44-pin TQFP form factor with rich peripheral integration. Its low-voltage operation down to 1.8 V makes it compatible with energy-harvesting and battery-powered IoT edge devices where supply rails may sag below 3.3 V. The compact TQFP-44 footprint and wide peripheral mix reduce BOM complexity in multi-channel control designs without requiring additional glue logic.

Frequently Asked Questions
Down to what supply voltage does the PIC16LF18875 operate, and which battery configurations does that enable?
The PIC16LF18875 (PIC16L variant) operates from 1.8 V to 3.6 V, making it compatible with a single-cell Li-Ion battery discharged below 3 V, two-cell NiMH packs at 2.4 V nominal, and energy-harvesting supplies as low as 1.8 V. This range extends run time compared with a standard 2.3 V minimum microcontroller by allowing deeper battery discharge.
How does the TQFP-44 package of the PIC16LF18875 compare to a 28-pin SOIC for a multi-peripheral control board?
The TQFP-44 package provides 44 pins in a 10 mm × 10 mm, 0.8 mm pitch footprint, offering significantly more I/O lines than a 28-pin SOIC, which exposes at most 22 to 24 I/O pins. For designs needing simultaneous SPI display, I2C sensor bus, UART debug port, and 8 PWM outputs, the 44-pin count avoids I/O expander chips and their associated firmware overhead.
Which communication interfaces are integrated in the PIC16LF18875, and how do they reduce external component needs in an industrial sensor node?
The PIC16LF18875 includes multiple UART, SPI, and I2C master/slave modules plus a 10-bit or 12-bit ADC with multiple channels, allowing direct connection to RS-232 transceiver chips, SPI flash memory, and I2C environmental sensors without additional serial-to-parallel or interface bridge ICs. This integration cuts BOM cost by 3 to 5 components per sensor node and simplifies PCB routing in compact 4-layer industrial designs.
