Real Time Clock Procurement Notes

Verify the specific ordering suffix AC3 against the manufacturer's official datasheet to ensure compatibility with required voltage levels and package variants. Confirm that the I2C address and pinout match the target design specifications. Check for RoHS compliance status and lead-free soldering requirements relevant to the assembly process. Ensure the 12-TFSOJ footprint aligns with the PCB layout constraints.

Real Time Clock Selection Notes

Select this component when a compact RTC with low current draw is required for I2C-based designs. The wide operating voltage range allows flexibility in power supply design. Consider the 12-TFSOJ package size for space-constrained applications. Verify that the industrial temperature range meets the environmental conditions of the end product. Ensure the system can support the I2C protocol speed supported by the device.

Real Time Clock Part Context
