Product details

The Microchip PIC18F05Q41-I/SL is an 8-bit PIC MCU running at 64 MHz, with 32 KB Flash program memory, 2 KB RAM, and 512 bytes of EEPROM on-chip.

Memory and analog integration — fewer external parts

With 32 KB Flash and 2 KB RAM, this part handles moderate firmware loads — sensor polling, control loops, communication stacks — without needing external memory. The 512-byte EEPROM stores calibration constants and configuration data that survive power loss, eliminating an external serial EEPROM. The 11-channel 12-bit ADC and dual 8-bit DAC cover analog sensor input and simple analog output generation, reducing the analog BOM count.

The 14-pin SOIC package (3.90 mm width) fits compact PCB layouts and is hand-solderable for prototyping.

Microchip lists the PIC18F05Q41-I/SL as Active. The part is ROHS3 compliant.

Frequently asked questions

Is PIC18F05Q41-I/SL equivalent to PIC18F05Q40?

The base product number is PIC18F05Q41. The PIC18F05Q40 is a different variant within the same family; the '41' suffix typically indicates additional features or memory. Check the Microchip datasheet for the exact delta between the two order codes.
