Frequently Asked Questions
What is the minimum supply voltage for PIC16LF18854-I/SO and how does it affect the clock frequency?
PIC16LF18854-I/SO operates from a minimum supply of 1.8V at up to 16 MHz, and can run at its full 32 MHz maximum clock when the supply is at least 2.3V. This voltage-frequency flexibility makes it ideal for battery-powered designs that throttle clock speed to conserve energy as battery voltage drops, extending operational lifetime in IoT sensors and wearable devices.
How many communication interfaces does PIC16LF18854-I/SO provide in the 28-pin SOIC package?
In the 28-pin SOIC package, PIC16LF18854-I/SO provides 2 SPI interfaces, 2 I2C (TWI) interfaces, and 1 EUSART (UART/SPI), all configurable via Peripheral Pin Select (PPS) for flexible pin mapping. This rich peripheral set enables connecting multiple sensors, displays, and communication modules simultaneously without requiring external I/O expanders.
What storage options does PIC16LF18854-I/SO offer for non-volatile configuration data?
PIC16LF18854-I/SO includes 256 bytes of on-chip EEPROM data memory alongside its program Flash, enabling persistent storage of calibration coefficients, device addresses, or user settings without external EEPROM ICs. The EEPROM endures at least 100,000 erase/write cycles with greater than 40-year data retention, suitable for storing parameters that change occasionally during product lifecycle.
For a low-power IoT sensor design, what advantages does PIC16LF18854-I/SO offer over a standard 5V PIC16?
PIC16LF18854-I/SO operates from 1.8V to 3.6V, making it directly compatible with common 3.3V IoT radio modules and 2-cell alkaline or single-cell Li-Ion battery supplies without a voltage regulator. Its 10-bit ADC with hardware computation (ADC2) enables averaging and threshold detection in hardware, reducing active CPU cycles and lowering average current consumption below 1 mA in duty-cycled applications.
