SPI Serial Flash Devices Tout Reduced Pin Count

The Serial Peripheral Interface (SPI) serial flash devices use a three-wire interface, which is said to result in a lower pin count for the ICs. Three devices make up the family: the 512-Kb SST45VF512, the 1-Mb SST45VF010, and the 2-Mb SST45VF020. Each device features low power consumption, in-system programmability and a small 8-pin SOIC package. Key features include single 2.7V to 3.6V read/write operation, a single interface architecture, 100,000 cycles endurance (typical) and greater than 100 years of data retention, an active current of 20 mA typical, and a typical standby current of 10 µA. Price ranges from $0.85 to $1.50.
