Frequently Asked Questions
At what minimum supply voltage can the PIC16LF18855-I/SS operate reliably?
The PIC16LF18855-I/SS operates down to 1.8 V supply voltage at clock speeds up to 16 MHz, enabling direct use with single-cell lithium-ion and alkaline battery systems without a boost regulator. At the full 3.6 V supply it runs at up to 32 MHz for more compute-intensive tasks.
How does the on-chip EEPROM in PIC16LF18855-I/SS benefit embedded data logging designs?
The 256 bytes of on-chip EEPROM allow firmware to store calibration constants, device addresses, and configuration data without an external memory IC, saving board space and BOM cost. EEPROM cells are rated for 100,000 erase/write cycles and data retention exceeding 40 years, meeting the durability needs of industrial and medical applications.
Which sensor interface scenarios make PIC16LF18855-I/SS a better fit than a pure digital 8-bit MCU?
When a design includes analog sensors such as thermistors, pressure sensors, or light-dependent resistors, the integrated ADC on PIC16LF18855-I/SS eliminates the need for a separate ADC chip. With up to 24 analog input channels available in the 28-pin package, designers can directly digitize multiple sensor signals within one IC operating from 1.8 V to 3.6 V.
How does the SSOP-28 package of PIC16LF18855-I/SS compare to a standard DIP option for space-constrained PCBs?
The SSOP-28 package body measures approximately 10.2 mm x 5.3 mm with 0.65 mm pin pitch, occupying roughly 60% less board area than a comparable 28-pin 0.6-inch DIP package. This footprint reduction is critical in compact IoT modules, wearable devices, and industrial sensor boards where every square millimeter of PCB space matters.
