Procurement Notes

Verify the specific suffix 'A' against official Renesas documentation to confirm exact revision or variant details, as standard listings may reference the base 90E32 model. Confirm availability status, as this series may be discontinued or subject to last-time buy notices. Ensure the 48-TQFP package matches your PCB footprint requirements. Check RoHS compliance status for environmental regulations.

Selection Notes

Select this component when designing three-phase metering solutions requiring integrated polyphase processing. Consider the 48-TQFP package size and the 2.8V to 3.6V supply voltage range during system architecture planning. Evaluate the 0.5% measurement error specification against required accuracy classes. Verify that the available input impedance options align with the connected current transformer or voltage divider networks.
