Microchip 64 kB Serial EEPROM 100 ns 8-Pin PDIP Serial-SPI 25LC640A-I/P

Microchip 25LC640A-I/P Serial EEPROM is a high-performance, non-volatile memory device featuring 64 kB capacity organized as 8K x 8 bits. It uses a Serial Peripheral Interface (SPI) for high-speed serial communication with a maximum clock frequency of 10 MHz, offering fast and efficient data access.

This EEPROM is housed in an 8-Pin PDIP package with through-hole pin mounting, making it compatible with a variety of circuit board assembly methods. It operates reliably over a broad temperature range from -40°C to 85°C, supporting industrial and automotive applications.

The device supports a minimum supply voltage of 2.5 volts up to a maximum of 5.5 volts, providing flexibility across different power levels. Its very low supply current of 5 mA ensures efficient power usage. With a maximum random access time of only 100 nanoseconds, the 25LC640A-I/P supports rapid read and write cycles.

Designed to meet the automotive standard AEC-Q100, this EEPROM guarantees robustness and long-term stability. It also features an exceptional data retention capability of 200 years, making it ideal for archival storage or critical data logging in embedded systems.

With physical dimensions of 9.4 mm in length and 6.35 mm in width, this compact EEPROM device is suited for space-constrained electronics requiring reliable serial memory. Its organization as 8K words of 8 bits each facilitates easy memory addressing and data management.
