The onsemi LE25S40FD-AH is a 4 Mbit NOR Flash memory component organized as 512K x 8 bits. This device operates via a Serial Peripheral Interface (SPI) bus, supporting a maximum clock frequency of 40 MHz. Manufactured using CMOS technology, it features a nominal supply voltage of 1.8V and a standby current of 10 µA. The LE25S40FD-AH offers robust endurance of 100,000 program/erase cycles and data retention exceeding 20 years. It supports both hardware and software write protection mechanisms. Packaged in an 8-lead Small Outline Package (SOP) with a 1.27 mm terminal pitch, this component is suitable for surface-mount applications. Its operational temperature range is from -40°C to +85°C. This memory is commonly employed in industrial control systems, consumer electronics, and automotive applications where reliable non-volatile storage is critical.
