Frequently Asked Questions
What is the maximum clock frequency of the PIC18F13K22-I/SO, and at what minimum supply voltage does it operate?
The PIC18F13K22-I/SO reaches a maximum clock frequency of 64 MHz at its nominal supply voltage, and it continues to operate at 20 MHz from as low as 2.3 V, supporting low-power and battery-powered applications. This flexibility allows designers to trade off performance for energy efficiency in sleep-wake duty-cycle systems.
How much non-volatile memory does the PIC18F13K22-I/SO provide for data logging applications?
The PIC18F13K22-I/SO includes 8 KB of flash program memory and 256 bytes of data EEPROM for persistent parameter or log storage without external memory ICs. The 256 bytes of RAM support runtime variable storage and data buffering, making it adequate for compact sensor logging firmware running at up to 64 MHz.
Why might an engineer choose the PIC18F13K22-I/SO over a PIC16-series MCU for the same application?
The PIC18 core in the PIC18F13K22-I/SO offers a richer instruction set, higher clock speed up to 64 MHz, and a larger address space than PIC16 devices, allowing more complex firmware with fewer instruction cycles. The 8 KB flash and 256 bytes EEPROM also provide more code and data storage than typical PIC16 entry-level parts, which usually top out at 3.5 KB to 7 KB flash and 20 MHz maximum clock.
Is the PIC18F13K22-I/SO drop-in compatible with other 20-pin SOIC Microchip MCUs?
The PIC18F13K22-I/SO uses the standard 20-pin SOIC footprint, sharing physical pinout compatibility with other PIC18F 20-pin family members such as the PIC18F14K22. Firmware migration requires re-evaluation of peripheral registers and clock settings, but the PCB layout and 5 mm body width of the SOIC-20 package remain interchangeable across compatible PIC18 variants.
