Microcontrollers Procurement Notes

Verify that the ordering suffix 'T' corresponds to tape-and-reel packaging and 'SS' indicates the SSOP-28 package. Confirm the '-I' suffix denotes the industrial temperature range of -40°C to +85°C. Ensure compatibility with In-Circuit Serial Programming requirements before procurement.

Microcontrollers Selection Notes

Select this component when 8 KB of program memory and 256 bytes of EEPROM are sufficient for the application logic. Choose this part over larger variants like the PIC18F25K22 if pin count and memory size constraints require a smaller footprint. Verify that the 2.3V minimum operating voltage aligns with the system power design.

Microcontrollers Part Context

This device belongs to the PIC18(L)F2X/4XK22 family, which shares identical peripheral sets across members. Differences between family members are limited to program memory size, data memory capacity, I/O port counts, and specific voltage ranges. The PIC18F23K22 represents the entry-level configuration within the 28-pin subset of this family.

Microcontrollers Replacement Considerations

PIC18LF23K22T-I/SS offers the same functionality with a lower 1.8V to 3.6V operating voltage range. PIC18F24K22T-I/SS provides increased memory resources while maintaining the same package and pinout.
