This makes it a strong fit for applications that log data, update firmware in the field, or wake from sleep to capture a sensor reading without waiting for a write cycle to complete.
The integrated 12-bit ADC with 16 channels covers analog sensor inputs without an external converter.
It is a current-production device, available through independent distribution.
Engineers need full electrical specs, pinout, and timing diagrams to verify fit.
Sourcing buyers need to find authorized distributors, check stock, and get quotes.
Price directly impacts BOM cost and project budget decisions.
Design engineers and buyers need to avoid obsolete parts and plan lifecycle support.
Layout engineers require accurate pin assignment for PCB design.
When stock is low or lead times long, a drop-in alternative saves redesign effort.
