The Microchip Technology 25C640X-E-ST is an 8K x 8 serial EEPROM utilizing advanced CMOS technology. This component offers a substantial memory density of 65536 bits and operates synchronously via an SPI serial bus. Key features include a maximum clock frequency of 3.00000 MHz and a wide operating temperature range from -40.0°C to 125.0°C. Data retention exceeds 200 years, and the device is protected by 4KV ESD protection, with an endurance rating of 1 million write cycles. The PDSO8 package, a thin profile TSSOP with a 0.650mm terminal pitch, is suitable for surface mounting applications. This memory solution is commonly employed in industrial control, automotive systems, and consumer electronics where reliable non-volatile data storage is critical. The supply voltage range is 4.5V to 5.5V.
