Additional Details

The S29GL256P90TFIR2 operates at a specific supply voltage, typically 3.0V. The device is commonly available in a 56-pin TSOP (Thin Small Outline Package) or similar package. The operating temperature range is typically -40°C to +85°C. The endurance rating, which specifies the number of program/erase cycles the device can withstand, is an important consideration for applications with frequent data updates. The device also includes features such as hardware and software write protection to prevent accidental data corruption. Detailed electrical characteristics, timing diagrams, and other specifications are available in the product datasheet from Infineon Technologies.
