Technical Specifications

The S29GL256N11FFIIH operates at a supply voltage of 3.0V. The read access time is 110 ns. The erase cycle endurance is rated for 100,000 cycles per block. The operating temperature range is from -40°C to +85°C. The package is a 56-pin TSOP (Thin Small Outline Package). The memory array is organized into uniform 128KB blocks for erase operations. It features a parallel data interface and control signals for read, write, and erase operations. The device supports sector protection features to prevent accidental overwrites. Power consumption during read operations is typically low, making it suitable for battery-powered applications. The standby current is extremely low to minimize power drain when the device is not actively being used. The device is RoHS compliant and lead-free. The boot sector configuration allows flexibility in system boot-up procedures.
