The SST25VF040B-50-4I-SAE-T is a 4 Mbit serial flash memory featuring a four-wire, SPI-compatible interface. It operates from a single 2.7V to 3.6V supply and supports a high-speed clock frequency of up to 50 MHz. This device is specified for the industrial temperature range of -40°C to +85°C and offers a minimum endurance of 10,000 erase/write cycles. Key features include flexible erase capabilities with 4-Kbyte sectors, low power consumption with a typical standby current of 5 µA, and software write-protection. Its low pin-count 8-lead SOIC package makes it ideal for applications where board space and system cost are critical factors.
