FM93C46LN

The On Semiconductor FM93C46LN is a 1024-bit (1Kbit) CMOS non-volatile EEPROM organized as a 64 x 16-bit array. It utilizes the MICROWIRE™ synchronous bus interface, compatible with many microcontrollers and microprocessors, featuring chip select (CS), clock (SK), data input (DI), and data output (DO) signals.

This EEPROM operates with a wide supply voltage range of 2.7V to 5.5V and has an operating temperature range of 0°C to 70°C. Key electrical characteristics include a typical active current of 200µA and a very low standby current of 0.1µA for the LZ version, making it suitable for low-power applications. It boasts 40 years of data retention and an endurance of 1,000,000 data changes.

The FM93C46LN is available in an 8-pin DIP package, designed for through-hole mounting. It supports a clock frequency of up to 250kHz and features a write cycle time of 15ms. The device simplifies design by not requiring an erase instruction before a write operation and includes self-timed write cycles with device status indication during programming.

This component is ideal for embedded systems requiring non-volatile data storage, such as configuration settings, calibration data, or small program storage. Its robust design and standard interface make it a reliable choice for industrial and consumer electronics.
