Internal oscillator is on-chip, saving an external crystal for UART or I²C timing at moderate baud rates.
Connectivity and I/O – serial bus options
With 24 I/O pins in a 28-pin package, the pin-to-function ratio is efficient for compact designs.

Buyers need to check availability and cost for BOM planning and procurement decisions.
Engineers must validate fit, pinout, and electrical characteristics before design-in.
Sourcing buyers need alternatives if the part is scarce, obsolete, or too expensive.
Project timelines depend on delivery schedules; long lead times can cause delays.
Engineers and buyers need to know lifecycle status to avoid future supply issues.
Designers must confirm pin compatibility with PCB layout and peripheral connections.
