Product details

Memory sizing — 32 KB Flash with 512 B EEPROM

The 2 KB RAM handles a couple of UART buffers and a modest state machine — if your application needs a large frame buffer or a TCP/IP stack, step up to a part with more SRAM.

On the peripheral side you get I2C, SPI, UART/USART, and LINbus — enough for common sensor and actuator buses — plus 12 general-purpose I/O lines. The integrated 11-channel 12-bit ADC and dual 8-bit DAC cover basic analog front-end tasks without an external converter.

The 14-SOIC package (0.154" wide, 3.90 mm body) is a hand-solderable, hot-air-friendly footprint.

Frequently asked questions

Is PIC18F05Q41T-I/SL pin compatible with PIC18F05Q41?

Yes — the base product number PIC18F05Q41 is the same; the 'T' suffix indicates Tape & Reel packaging, and the '-I/SL' suffix denotes the industrial temperature grade and 14-SOIC package. The silicon and pinout are identical.

Can PIC18F05Q41T-I/SL replace PIC18F05Q41-I/SL?

Yes — the 'T' suffix only changes the shipping medium to Tape & Reel; the die, firmware, pinout, and temperature grade are identical. A direct drop-in replacement.
