onsemi Memory FM93C66LVMT8

The FM93C66LVMT8 is a 4096-bit CMOS non-volatile EEPROM organized as a 256 x 16-bit array, featuring a MICROWIRE interface that is compatible with various microcontrollers and microprocessors. It supports seven instructions for Read, Write, Erase, and Write Enable/Disable operations. The device operates within a voltage range of 2.7V to 5.5V and has a typical active current of 200µA, with standby currents as low as 0.1µA for the LZ version, making it suitable for low-power applications. The FM93C66LVMT8 is designed for high reliability and endurance, with a data retention period of up to 40 years and an endurance of 1,000,000 data changes. It is available in multiple package types, including 8-pin SO and 8-pin TSSOP, catering to space-constrained designs. The device does not require an erase instruction before writing, and it features self-timed write cycles, enhancing its usability in various applications.
