It combines the read/write speed of SRAM with on-chip non-volatile storage, so it retains data through power loss without an external battery backup. This makes it a direct fit for industrial controllers, telecom line cards, and metering equipment where configuration logs or calibration constants must survive unplanned power cycles. For a 16-bit controller running at 20 MHz to 33 MHz, this typically allows zero-wait-state reads if the controller's memory interface timing closes within that window. At higher bus speeds (above 40 MHz) you will likely need a single wait state, so check the controller's tACC requirement against the 45 ns spec before committing the layout. ## No battery, no worry — the NVSRAM advantage Standard SRAM loses data when power drops, forcing designers to add a battery or supercapacitor and a power-fail detection circuit. The CY14B108N-ZSP45XI eliminates that: its internal non-volatile elements store the SRAM array on power-down and restore it on power-up, all within the same 45 ns access cycle. That saves board space, removes battery-replacement maintenance, and improves reliability in remote or sealed enclosures. It comes in a 54-TSOP II surface-mount package (10.16 mm body width). ## Supply range and write timing The write cycle time (word or page) is also 45 ns, so read and write cycles run at the same speed — no asymmetric penalty when updating configuration tables or logging data.","metaTitle":"Infineon CY14B108N-ZSP45XI NVSRAM, 8Mbit, 45 ns, 54-TSOP II","metaDescription":"Infineon CY14B108N-ZSP45XI 8Mbit NVSRAM, 45 ns access time, parallel interface, 2.7V-3.6V, -40°C to 85°C, 54-TSOP II.
