M95640-DFDW6TP IC EEPROM 64KBIT SPI 8TSSOP STMicroelectronics

 

DESCRIPTION

These electrically erasable programmable memory (EEPROM) devices are fabricated with STMicroelectronics’ High Endurance, Double Polysilicon, CMOS technology. This guarantees an endurance typically well above one hundred thousand Erase/Write cycles, with a data retention of 40 years. The memories are organised as 8K x 8 bits and 4K x 8 bits (M95640, M95320) and 2K x 8 bits and 1K x 8 bits (M95160, M95080), and operate down to 2.5 V (for the -W version of each device), and down to 1.8 V (for the -R version of each device).
