Product details

28 KB Flash in a 14-pin body — what fits

It runs at 32 MHz from an internal oscillator, so no external crystal is needed for most timing tasks.

14-TSSOP — rework and routing

The 14-TSSOP (0.173" body width, 4.40 mm) is a fine-pitch SOIC variant — 0.65 mm lead pitch, easy to hand-solder with a decent iron and flux, and forgiving under hot air if you need to lift it. The 11 I/O are on the perimeter, so a two-layer board routes cleanly. No thermal pad to worry about; the package dissipates through the leads.

ROHS3 compliant. If a second-source hedge matters, the PIC16LF1559-I/SS is a close functional peer in the same PIC 16F family, though in a 20-pin SSOP package — verify pin compatibility if you need a drop-in alternate.

Frequently asked questions

What is the flash memory size of PIC16F18126-I/ST?

The PIC16F18126-I/ST has 28 KB of Flash program memory (28K x 8). That's enough for moderate firmware — sensor fusion, LINbus node, or a small motor-control loop — without needing external storage.

How many I/O pins does PIC16F18126-I/ST have?

It provides 11 I/O lines in the 14-TSSOP package. With the 12-bit ADC muxed across 29 channels, you can read many analog inputs but only drive 11 digital outputs — plan the pin budget accordingly.
