Lifecycle

Current status: No public indication of near-term discontinuation based on available data

Alternatives: Consider RL78/I1C family variants with different Flash sizes, pin counts, or packages to match your needs (e.g., same RL78/I1C series with 32KB/128KB Flash or 64-/100-pin options). Exact cross-references depend on I/O count, ADC needs, and LCD requirements.

If you need exact equivalent or pin-compatible options, please contact our sales team via the Y-IC website for a tailored shortlist and lifecycle updates.
