Chip lifecycle / Product types / Derivative product

Derivative product

Silicon programme, one of the Hub's ten product types. Each type runs only the lifecycle stages and gates its kind of change needs.

What it is

Silicon programmeWork that creates or changes a die, from a new platform to a fix in the metal layers.

A new orderable device built from a qualified platform. It differs from its parent in feature set, channel count, memory size, integration or performance grade, reuses the platform's architecture and IP, and needs a full mask set.

Typical triggers

A market or lead-customer request that the platform can meet with a bounded design change
A cost-reduced or feature-reduced version of a released part
A new memory size, channel count or peripheral mix on an existing platform

Examples

A reduced feature derivativeA smaller version of a released chip with some blocks removed, on the same node and architecture.
A higher channel count variantMore instances of an existing interface on the same platform, sold as a new part in the family.
A memory size variantA microcontroller derivative with a different memory size and peripheral set.

Examples are generic: they describe a kind of work, not any company's product.
