Frequently Asked Questions

How does nanoWatt XLP technology in PIC18F26K22-I/SS benefit battery-powered sensor designs?

PIC18F26K22-I/SS nanoWatt XLP technology reduces sleep mode current to below 100 nA, significantly extending battery life in applications that spend most time in standby. For a sensor node waking every 10 seconds to sample and transmit data, this sleep current reduction translates to years of operation from a single AA cell compared to devices with typical sleep currents of several microamperes.

What is the maximum clock frequency of PIC18F26K22-I/SS and at what supply voltage does it operate?

The PIC18F26K22-I/SS achieves a maximum clock frequency of 64 MHz, delivering approximately 16 MIPS of processing throughput. It operates over a supply voltage range of 2.3 V to 5.5 V, with full 64 MHz performance available from 3 V and above, and reduced 20 MHz operation supported at the 2.3 V minimum supply for ultra-low-voltage battery applications.

Which communication interfaces does PIC18F26K22-I/SS support for connecting peripherals?

The PIC18F26K22-I/SS integrates multiple serial communication peripherals including two MSSP modules that support SPI and I2C protocols, plus two EUSART modules for RS-232 and RS-485 compatible UART communication. This combination allows simultaneous connection to SPI sensors, I2C EEPROMs, and UART-based wireless modules in a single 28-pin SSOP device without external glue logic.

How does the 64 KB Flash of PIC18F26K22-I/SS compare to smaller PIC18 variants for firmware complexity?

The 64 KB Flash of PIC18F26K22-I/SS provides approximately 32,768 program words, supporting complex firmware including USB stacks, proprietary wireless protocols, and multi-task real-time operating systems. Smaller PIC18 variants with 32 KB or 16 KB of Flash constrain firmware size, making PIC18F26K22-I/SS the preferred choice when code size requirements exceed 20 KB or when over-the-air bootloader support is needed alongside application code.
