CYPT16B256-133FZMB

Infineon’s radiation tolerant, the CYRS16B and CYPT16B, serial NOR Flash family offers the industry’s highest performance, small footprint memory devices that are QML-V equivalent qualified

Our radiation tolerant NOR flash memories are low pin count, low power and offer flexibility, reliability and performance well beyond ordinary serial flash devices.  The industry standard QSPI interface is high performance and simple to use with broad ecosystem support.
