Frequently Asked Questions
What is the flash and RAM size of PIC18F25K22-E/ML and how does it compare to similar PIC18 devices?
PIC18F25K22-E/ML provides 32 KB of program flash and 1.536 KB of data RAM. Compared to PIC18F24K22 which has 16 KB flash, the PIC18F25K22 offers double the code space in the same 28-pin VQFN-28 footprint, making it a pin-compatible upgrade for firmware that has outgrown the smaller variant without requiring a PCB redesign.
How low is the sleep current of PIC18F25K22-E/ML and what battery life does that enable?
PIC18F25K22-E/ML draws as little as 20 nA in deep sleep mode using XLP technology. With a 225 mAh CR2032 coin cell, this corresponds to over 100 years of theoretical sleep time, meaning the device's practical lifetime is limited by the battery's shelf life of approximately 10 years, not by active sleep drain.
Does PIC18F25K22-E/ML support SPI and I2C communication for connecting external sensors?
Yes, PIC18F25K22-E/ML includes 2 MSSP (Master Synchronous Serial Port) modules, each configurable as either SPI or I2C master or slave at clock frequencies up to 10 MHz for SPI and 400 kHz for I2C fast mode. This allows the MCU to communicate simultaneously with, for example, an SPI flash memory and an I2C temperature sensor on separate buses.
For a 3.3 V sensor hub design needing analog inputs, how many ADC channels does PIC18F25K22-E/ML provide?
PIC18F25K22-E/ML provides an 11-channel 10-bit ADC, capable of measuring 1024 discrete levels across the reference voltage range. At a 3.3 V supply with an internal or external 3.3 V reference, the ADC resolution is approximately 3.2 mV per LSB, which is sufficient for temperature, pressure, and light sensors in a 3.3 V-powered hub running at up to 64 MHz.
