Frequently Asked Questions
How low can the supply voltage go for the PIC16LF18875T-I/MV, and at what clock speed does it operate at minimum voltage?
The PIC16LF18875T-I/MV operates from a minimum supply of 1.8V at up to 16 MHz, making it suitable for single-cell lithium coin batteries that discharge down to 1.8V near end of life. At 3.3V or higher supply, the device scales up to its full 32 MHz clock rate for higher throughput tasks.
What integrated analog peripherals does the PIC16LF18875T-I/MV include that reduce external component count?
The PIC16LF18875T-I/MV includes both an ADC and DAC channels on-chip, eliminating the need for separate analog converter ICs in many designs. The built-in DAC allows direct generation of reference voltages or waveform signals up to the supply rail, saving board space and reducing BOM cost by 2 to 4 components in typical sensor interface circuits.
For a wearable medical sensor running from a 3V coin cell, how does the PIC16LF18875T-I/MV memory capacity hold up?
With 14KB of Flash, 1KB of RAM, and 256 bytes of EEPROM, the PIC16LF18875T-I/MV provides enough space for a BLE-bridge firmware image, a circular sample buffer, and persistent calibration coefficients. At 16 MHz from a 1.8V coin cell supply, the MCU can sustain 1 kHz ADC sampling with deep-sleep duty cycling, extending battery life beyond 6 months.
When is the PIC16LF18875T-I/MV preferable to the PIC16F18875 for industrial sensor applications?
The LF variant is preferred when the system voltage rail is 1.8V to 3.6V, such as in battery-backed or energy-harvested industrial sensors. The standard PIC16F18875 requires a minimum of 2.3V, so in designs where supply can dip below 2.3V—common in long-life deployments—the LF variant provides guaranteed operation down to 1.8V at 16 MHz without additional regulation.
