Frequently Asked Questions
What is the minimum supply voltage of PIC16LF18444-E/GZ and which battery types does this support?
PIC16LF18444-E/GZ operates from as low as 1.8 V at 16 MHz, making it compatible with single-cell coin cell batteries (CR2032 at approximately 3 V nominal down to 2 V end-of-life), thin-film batteries, and 2 × AA alkaline cells without requiring a step-up regulator.
How does the 20-pin UQFN EP package of PIC16LF18444-E/GZ benefit miniaturized IoT hardware designs?
The 20-pin UQFN EP package has a footprint of approximately 3 mm × 3 mm with an exposed thermal pad, providing 8-bit MCU capability with ADC and DAC in a very small PCB area suitable for BLE beacon accessories, smart labels, and miniature wearable sensor nodes.
Which peripherals on PIC16LF18444-E/GZ eliminate external analog components in sensor designs?
PIC16LF18444-E/GZ integrates both ADC channels for analog sensor signal digitization and DAC channels for analog output generation, eliminating the need for external analog-to-digital and digital-to-analog converter ICs in temperature, humidity, and pressure sensor node designs running from a 1.8 V to 5.5 V supply.
When should PIC16LF18444-E/GZ be preferred over a standard PIC16F18444 for a low-voltage design?
PIC16LF18444-E/GZ is the low-voltage variant with 1.8 V minimum supply compared to the standard PIC16F18444 which requires at least 2.3 V; the LF suffix device is the correct choice when powering directly from a coin cell or thin-film battery that drops below 2.3 V during discharge, ensuring full 32 MHz operation throughout the battery life cycle.
