Frequently Asked Questions
How low a supply voltage can PIC16F19156-I/MV operate from, and which battery chemistries does this enable?
PIC16F19156-I/MV operates from a minimum supply voltage of 2.3 V at 16 MHz, enabling use with single-cell lithium batteries (3.0 V to 4.2 V) and two-cell NiMH packs (2.4 V nominal). This low voltage floor extends battery run time significantly in wearable and IoT sensor designs by allowing deeper discharge cycles.
For a compact IoT sensor board, how much PCB space does the UQFN-28 package of PIC16F19156-I/MV occupy?
The UQFN-28 package of PIC16F19156-I/MV measures approximately 4 mm x 4 mm with a 0.5 mm pin pitch, providing 28 pins in an ultra-compact footprint. This is significantly smaller than equivalent PDIP-28 packages, freeing board space for RF modules, sensors, and power management in miniaturized IoT nodes.
Which embedded control scenarios benefit most from PIC16F19156-I/MV running at 32 MHz with integrated ADC?
PIC16F19156-I/MV running at 32 MHz is well-suited for applications requiring fast analog sampling and responsive control loops, such as motor soft-start controllers, PID temperature regulators, and capacitive touch sensing with 8-bit precision ADC results. The integrated ADC eliminates the need for external analog-to-digital conversion ICs, reducing BOM cost.
When is PIC16F19156-I/MV a cost-effective alternative to 32-bit microcontrollers for simple sensor applications?
For applications involving straightforward analog sensing, digital I/O toggling, and UART communication without complex data structures, PIC16F19156-I/MV delivers sufficient 8-bit performance at 32 MHz with lower unit cost than 32-bit MCUs. Its 28-pin count also reduces PCB routing complexity compared to higher-pin 32-bit alternatives.
