Frequently Asked Questions
At what voltage and clock speed does PIC16F18325-I/JQ operate, and what are the implications for battery life?
PIC16F18325-I/JQ operates at a minimum of 2.3 V when running at 16 MHz, and can function at even lower supply voltages when the clock is reduced below 16 MHz. This allows direct use with a single lithium coin cell or two AA alkaline batteries without an LDO, extending battery life in sensor nodes by eliminating regulator quiescent current loss of typically 50 µA to 100 µA.
How much non-volatile memory does PIC16F18325-I/JQ provide and how is it split between Flash and EEPROM?
PIC16F18325-I/JQ provides 14 KB of Flash program memory for firmware storage and 256 bytes of EEPROM for non-volatile data retention without external SPI or I2C memory devices. Additionally, 1 KB of SRAM is available for runtime variable storage, which is sufficient for most 8-bit sensor acquisition and communication stacks running simple UART or SPI protocols.
Which embedded peripherals in PIC16F18325-I/JQ reduce external component count in analog sensor designs?
PIC16F18325-I/JQ integrates an ADC with multiple input channels for direct analog sensor reading, plus at least 1 DAC channel for voltage reference or signal generation, eliminating the need for a standalone ADC chip. The PIC16 core also includes hardware UART, SPI, and I2C interfaces, meaning a complete sensor node with wired communication can be built with the MCU and fewer than 5 passive components on a board as small as 5 mm × 5 mm.
When is PIC16F18325-I/JQ a practical alternative to PIC16F18345 in a new design?
PIC16F18325-I/JQ is a preferred choice over PIC16F18345 when the application requires only 14 KB Flash and fewer I/O pins, as the 16-pin UQFN package costs less and occupies a smaller PCB area of approximately 3 mm × 3 mm. If more than 14 KB Flash, additional timers, or 20 or more GPIO pins are needed, upgrading to PIC16F18345 in a 28-pin SSOP is more appropriate, while PIC16F18325 remains the lower-cost solution for simpler control tasks.
