Backed by Y-IC supply assurance, technical guidance, and responsive support

Packaging

Supply formats include standard manufacturer Tape and Reel or Tray depending on order option

Package or case code indicated as 1330 by supplier listing

Lead finish is lead-free and RoHS compliant with halogen-free options in many lots

Package material is standard epoxy molding compound with copper leadframe as per Renesas norms

Pin configuration and pitch depend on the AFB package variant for this code. Check the datasheet package drawing for exact pin count, pitch, and land pattern

Moisture Sensitivity Level follows JEDEC classification. Follow the label on the reel or tray and the baking guidelines in the datasheet

Thermal characteristics such as θJA, θJC, and maximum power dissipation are defined in the datasheet. Plan PCB copper area and vias for heat spreading as recommended

Electrical characteristics such as operating voltage range, I/O levels, current consumption, and timing are defined in the datasheet. Verify against your system budget before design freeze

Lifecycle

As of our latest internal checks this Renesas device is active and widely used. Not flagged as near end of life

Direct, pin-compatible, or functionally similar alternatives can exist within the same Renesas family with different memory sizes, temperature grades, or packages

The exact cross reference depends on flash size, RAM, package type, temperature, and peripheral needs. Contact Y-IC sales on our website for a curated list tailored to your requirements and for second-source strategies
