This part comes in a 64-ball TFBGA (5x5 mm body) — fine-pitch, no exposed paddle. MSL 3 is typical for this class. Will it survive rework? Yes, with a decent preheat and a rework nozzle sized to the body. The small thermal mass reflows cleanly.
At 32 MHz the core draws in the low milliamps range; stop-mode current is typically under 2 µA with the RTC running.
Price directly influences sourcing decisions and budget planning.
Stock availability determines whether the part can be purchased now or requires a lead time.
Design engineers need full specs to validate fit and performance.
Buyers compare options to find the best fit or substitute in case of supply issues.
Distributor selection affects price, lead time, and shipping.
Pinout is critical for PCB layout and hardware integration.
