Engineering Selection Recommendations

All three parts—R5F564MFHDLK#21, R5F564MFCDLK#21, and R5F564MFGDLK#21—maintain Active product status with Renesas Electronics Corporation, ensuring long-term availability and manufacturing support. All parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for embedded applications.

Selection between these parts is based on inventory availability and supply chain logistics rather than functional or electrical differentiation. Each part carries identical electrical specifications, memory architecture, peripheral integration, and environmental operating ranges. PCB layout, firmware, and system integration remain unchanged across all three part numbers.

Frequently Asked Questions (FAQ)

Q: Can R5F564MFCDLK#21 or R5F564MFGDLK#21 be used as direct replacements for R5F564MFHDLK#21?

A: Yes. All three parts are parametrically equivalent across all electrical, memory, connectivity, and environmental specifications. No design modifications, PCB rework, or firmware changes are required for substitution.
