Memory IC Procurement Notes

Verify the specific suffix 'TR' confirms the tape and reel packaging configuration required for automated assembly processes. Ensure the operating temperature range meets the environmental specifications of the target application board. Confirm RoHS compliance status matches regulatory requirements for the destination market before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 32-bit wide memory interface is required for high-speed data processing applications. The 143 MHz speed grade offers a balance between performance and power consumption for industrial environments. Consider the 90-ball BGA footprint constraints during PCB layout design to ensure adequate clearance and thermal management for the surface mount package.
