For a system running a 20 MHz to 25 MHz bus, this gives roughly one clock cycle of margin after accounting for PCB trace delay and output hold times. If the design uses a faster memory controller (e.g., 50 MHz), the 45 ns part may force a wait state insertion — verify against the controller's setup/hold requirements. The parallel interface is straightforward to connect to most 8-bit MCUs and FPGAs, with no serial protocol overhead. For BOM planning, this part can be qualified into new designs without an immediate obsolescence watch. The NVSRAM format is a proprietary Cypress technology, so if a second-source is needed, the closest functional alternative is a battery-backed SRAM or a serial FRAM — but neither is a drop-in replacement for the parallel NVSRAM footprint. ## Package and footprint — 48-ball FBGA The 0.8 mm ball pitch is common for memory BGAs; the footprint matches Cypress's standard 48-FBGA layout for this density. Decoupling with a 0.1 µF ceramic per supply pin, placed as close to the balls as the via pattern allows, keeps switching noise within spec.","metaTitle":"Cypress CY14B101LA-BA45XI NVSRAM, 1Mbit, 45 ns, Parallel","metaDescription":"Cypress CY14B101LA-BA45XI NVSRAM: 1Mbit, 45 ns access, parallel interface, 2.7 V supply, -40°C to 85°C.
