Frequently Asked Questions
What is the minimum supply voltage for PIC16F1934-I/PTVAO, and which battery configurations does it support?
The PIC16F1934-I/PTVAO operates from a minimum 1.8V supply, supporting 2xAA alkaline cells (down to 1.8V end-of-life), single lithium primary cells, and 3.3V regulated rails up to 5.5V maximum. At 1.8V, the device runs at up to 16 MHz; full 32 MHz operation is available at higher supply voltages, making it versatile for wide battery-life and supply range designs.
How does the integrated LCD driver in PIC16F1934-I/PTVAO reduce BOM cost in handheld meter designs?
The PIC16F1934-I/PTVAO includes an on-chip LCD segment driver that directly drives glass LCD panels without an external LCD controller IC. This reduces BOM by eliminating at least 1 additional IC, its bypass capacitors, and I2C routing, simplifying the PCB layout for handheld thermometers, energy meters, and HVAC controllers that rely on a 4-digit or multi-segment 1.8V to 5V LCD display.
What non-volatile memory resources does PIC16F1934-I/PTVAO provide for parameter storage in a data logger?
The PIC16F1934-I/PTVAO includes 7KB of flash program memory, 256B of data EEPROM for non-volatile parameter and calibration storage, and 256B of RAM for runtime data. The on-chip EEPROM supports a minimum of 100,000 write cycles at operating temperatures from -40°C to 85°C, making it reliable for storing sensor calibration tables or configuration settings in battery-operated data loggers.
Which analog peripherals in PIC16F1934-I/PTVAO enable single-chip sensor measurement without external converters?
The PIC16F1934-I/PTVAO integrates a multi-channel ADC with up to 10-bit resolution for sensor input sampling and a DAC output for analog reference or signal generation. Combined with on-chip comparators and a voltage reference, these peripherals allow the 44-pin TQFP device to condition, convert, and display analog sensor data without any external ADC or DAC ICs, reducing BOM cost in standalone industrial measurement instruments.
