The CY7C199CN-12VXAT is a 256Kbit asynchronous SRAM from Infineon Technologies, organized as 32K x 8 bits with a 12 ns access time.
Infineon lists the CY7C199CN-12VXAT as Obsolete. No official successor or second-source is recorded on this order code. For a BOM that already carries this footprint and supply rail, the 12 ns speed grade and industrial temperature range are the binding constraints on any replacement candidate.
The CY7C199CN-12VXAT is obsolete per Infineon's lifecycle status. It is sourced to order through independent distribution — submit an RFQ for current availability and pricing. No stock-holding claim is made; each lot is confirmed at quote time.
