The CY14B101KA-ZS45XI is a 1 Mbit Non-Volatile SRAM from Infineon, organized as 128K x 8 bits. It combines the fast read/write cycles of an SRAM (45 ns access time) with automatic non-volatile storage on power loss, eliminating the battery, supervisor IC, and serial EEPROM that a standard SRAM backup scheme requires.
Submit an RFQ with your target quantity and delivery timeline; we will confirm availability and current pricing from our multi-source supply chain. The part ships in tray packaging, so confirm the tray count per reel or tube if your pick-and-place requires a specific format.
No — the product status is Active per Infineon's records. No PCN or EOL notice has been issued for this ordering code.
Pin-compatible NVSRAMs in the same 44-TSOP II footprint include other 1 Mbit parallel NVSRAMs from Infineon's CY14B101KA family (e.g., CY14B101KA-ZS45XIT for tape-and-reel). For a second-source option, look at the STMicroelectronics M48T35Y series (battery-backed SRAM) or the Cypress/Infineon FM28V100 series (F-RAM) — but verify the supply voltage and access time match your timing budget, as the interface and pinout differ.
